3 Common Screw Types at a Glance – Machine, Sheet Metal, and Cap Screws

Machine ScrewsMachine Screws

  •  Fully threaded shank
  • Usually used with a nut

  • Typically smaller than the average screw

  • Designed to be fastened to an existing tapped hole

Machine screws, also sometimes referred to as machine bolts, are normally smaller than the average screw. They usually range in sizes up to ¾ of an inch (19.05 mm), but can still come in larger variations. Typically machine screws are designed to be fastened to an existing tapped hole on a metal surface, usually in conjunction with a corresponding nut. The main differentiating characteristics of machine screws are: overall size, shape of head, slot type, length, material, and thread type.

The two main drive types associated with machine screws are slotted (flat head) and Phillips. There are also a number of specialized drives that they can come in, these are typically associated with tamper-resistant screws. Some of these drive types include, torx – six pointed, spanner, and trident to name a few. The shape of the head will determine how the machine screw lies once it’s fastened in place. Round and Pan heads will protrude from a flat surface, while flat head machine screws are designed for holes that are countersunk so that they lay flush with the surface.

Machine screws are always threaded the entire length of its shank. Threading on a machine screw is very important because the corresponding holes that they are being fastened into are typically tapped for a specific size and type of screw thread. The two main characteristics of threads are size of the outer diameter of the threads and pitch, the distance between each thread. Machine screw can be made to have either clockwise (right-handed) or counter-clockwise (left-handed) thread.

Sheet Metal ScrewsSheet Metal Screws

  • Fully threaded shank

  • Very versatile fastener, can be used in metal, wood, and plastics

  • Most are self-tapping screws and only require a pre-drilled hole, some come with self-drilling tips

  • Specially hardened, sharp threads that allow it to cut into material and form its own internal thread

Sheet metal screws have a fully threaded shank with sharp threads and tip that allow them to cut through metal, wood, plastic, and various other materials. The size of sheet metal screws are commonly shown as a series of three numbers, these numbers represent the diameter, thread count, and length of fastener. A sheet metal screw listed as 4-32 x 1-½” has a diameter size of 4, 32 threads per inch, and a length of 1-½”.

There are two basic types of sheet metal screws, self-tapping screws and self-drilling screws. Self-tapping screws have a sharp tip that is designed to cut through metal, but the metal must be pre-drilled before these screws can be used. Self-drilling screws have a drill point tip that can easily cut through metal without a pre-drilled hole.

The head of sheet metal screws can come in a number of different styles. Pan or round head screw will have heads that extend above the surface of the material after being installed. Flat or oval countersunk screws will be flush with the top of the material after being installed. These screws can come with a Phillips, flat, or combo drive.

Sheet metal screws made out of carbon steel are the most common and typically the most economical. These screws are prone to rust and corrosion when exposed to moisture or chemicals, so they should typically only be used indoors. Galvanized or stainless steel screws are designed to resist rust and corrosion, but tend to cost more than the standard steel screws. Sheet metal screws may be coated with zinc or nickel to modify their appearance.

Cap ScrewsCap Screws

  • Normally used without a nut

  • Available in both English and metric sizes

  • Fasten machine parts – home appliances / consumer electronic devices

  • Large head, diameter is larger than threaded portion

Cap screws have a large head and a cylindrical shaft with external threads. The head has a larger diameter than the threaded portion, this provides a positive mechanical stop when tightening the screw. Cap screws are tightened directly into a threaded or tapped hole, usually without a nut. A cap screw can generate a high amount of clamping force when tightened.

Commonly used cap screw heads styles include: hex head, socket head, and button head. Cap screws are typically  manufactured out of carbon steel, stainless steel, and metal alloys. The choice of type and size of of cap screw for a particular application mostly depends on the forces required to adequately secure the mechanical connection.

How do I Choose the Correct Self-Drilling and Self-Tapping Screws??

Self-Drilling Screws

Self-Drilling Screws operate on the same principles as drill bits and other cutting tools. This means that the way in which these screws are used affects their performance as much how they are designed.

Two important factors to consider when selecting a self-drilling screw are, material thickness and types of materials to be joined.

Screw Suitability

Optimal Cutting Parameters by Screw Size

 

 

 

 

 

 

Key Design Features to Consider when Selecting a Suitable Self-Drilling Fastener

  • Drill Flute

    • The length of the drill flute determines the metal thickness that can be drilled. Drill flutes allow the drilled material to exit the hole. If the drill flute becomes completely imbedded in the material, the drill chips will clog the flute and cause the cutting action to cease. If this occurs, the heat from the drill chips could cause the drill point to become over-heated and fail.

  • Point Length

    • The drill point is the unthreaded section from the drill point to the first thread. This length must be long enough to completely drill through the material before the threads engage. If the threads engage too early, they can cause the fastener to bind and break.

  • Screw Wings

    • It is necessary to use fasteners with wings when fastening wood, over ½” thick, to metal. The wings will ream a clearance hole and keep the threads from engaging too early. If the threads engage too early, this could cause a separation of the fastened material from the base material (jacking). Once the wings hit the metal material, they will break off allowing the threads to engage.

 

Self-Tapping Screws

Self-tapping screws can tap its own hole as it is being driven into it. They can come with a sharp, piercing tip or a flat, blunt tip. Sharp tipped self-tapping screws are designed for drilling their own hole in soft materials. The flat tipped self-tapping screws will need a pilot hole drilled before being installed. Some self-tapping screws are also self-drilling screws. These screws have a drill-like flute tip that looks like the tip of a center drill, along with the tap-like flute in the leading threads. These screws are very efficient in hard substrate applications.

How the Self-Tapping Ability is Created

  • Hard Substrates – Metal or Hard Plastics

    • Often created by cutting a gap in the continuity of the thread on the screw, this generates a flute and cutting edge similar to those on a tap.

  • Soft Substrates – Wood or Soft Plastics

    • The self-tapping ability can come simply from a tip that tapers to a gimlet point (no flute is needed), the point forms the hole by displacement of the surrounding material rather than any chip forming drilling / cutting / evacuating action.

  • Selection of cut is based on the material and finish required.
  • Double Cut burs have teeth that provide excellent stock removal on hard materials. They reduce bounce and chatter, offer excellent operator control, and produce a fine surface finish
  • Non Ferrous burs are recommended for soft materials that tends to load and pack in the flutes. These burs have open, aggressive cutting edges that allow easy chip flow and minimal clogging.
  • When using carbide burs, start at lower speeds and increase speed until the desired result is achieved.
  • When placing the carbide bur into the die grinder, it should be inserted into the collet as far as possible to minimize overhang.
  • Carbide burs should be feathered into the cut with even pressure to avoid digging into the material.
  • Do not apply excessive pressure, it can slow the spindle and chip cutting edges. Let the bur do the cutting.
  • Never encapsulate the bur in the cut.
  • Carbide burs, if used properly, will outperform HSS burs by 50:1.

Rollgliss R350 Rescue and Positioning Kit

One of the most versatile and efficient rescue and descent system on the market today is the Rollgliss R350 Rescue and Positioning Kit. The Rollgliss R350 system provides quick, safe, and effortless operation with state of the art technology and design. The R350 is pre-rigged, so it is ready to be quickly installed right out of the bag. But what makes this system so unique is that it is completely customizable by adding optional pulleys. With these optional pulleys the user can change the hauling ratio from 2:1 to 5:1 for added versatility and safety. The Rollgliss R350 is used to rescue an individual by either raising or lowering the victim to the ground or next level. To use the R350 system, it first needs to be anchored above the victim with the self locking / self closing carabiner equipped with the system. After anchoring, the rescuer can lower themselves down and attach to the fallen victim. Once attached, the rescuer gently raises them both up to relieve the pressure from the victim’s SRL or Lanyard in order to detach them from it. After safely being detached from their fall protection gear the rescuer can either lower or raise them both to a safe working location. Along with its rescue and descent abilities, the Rollgliss R350 can also be used for personal riding or work positioning applications. For these applications the user will typically need a Full Body Harness, boatswain’s chair or workseat, independent personal fall protection system, and of course the Rollgliss R350 Rescue and Positioning System.

DBI Sala Rollgliss R550 Rescue and Descent Kit

When rescuing a fallen worker the last thing you want to do is complicate the situation. The DBI Sala Rollgliss R550 Rescue and Descent Kit helps keep things simple. The R550 is the lightest, most compact, and easy to use design on the market. It offers the choice of rescue, evacuation, or the versatility of assisted rescue with lifting capabilities. This system can be used for a secure, automatic rescue and descent for cell phone towers, aerial lifts, cranes, wind towers, buildings, and much more. You can also choose between two different models: one with a rescue wheel or one without the rescue wheel (for descent applications only).

The DBI Sala Rollgliss R550 Rescue and Descent System is great to use in emergency escape situations. First secure the R550 to an anchor point. After anchoring, connect the snap hook to dorsal or front d-ring of harness and then you can descend safely down to the ground. In an assisted rescue situation secure the R550 to an anchor point. Once in position above the victim, securely attach the snap hook to the victims harness. Then gently raise the fallen victim so they can be unhooked from their fall protection gear. After they are unhooked, descend them safely to the ground. In situations where the victim is out of reach, you will need to perform a pick-off rescue. Secure the Rollgliss R550 to an anchor point and lower a second rescuer down to the victim. When they are in position the second rescuer can now securely attach themselves to the fallen victim. Once securely attached, they can be raised to safely unhook the victim from their fall protection gear. Once unhooked the rescuer and victim can safely descend down to the ground. The Rollgliss R550 Rescue and Descent System can also be used in custom rescue situations like an angled descent. The R550 system will need to be securely anchored on or near the ground. The rope will now need to be run through a pulley above the victim. Once attached to the rope, the victim can gently be raised so they can unhook from their fall protection gear. After being unhooked they can safely be lower to the ground, away from the structure.
