Thin Material Fastening & Blind Fastening Solutions in 1

Threaded Rivet Nuts Solve Thin Material & Blind Fastening Problems

When looking for fastening solutions for applications in thin materials where there is access from only one side of the working material, also known as a “blind” application, threaded rivet nuts can be the fasteners you are looking for. Threaded rivet nuts, also called blind threaded rivets, blind rivet nuts and threaded inserts, have the ability to provide permanent load-bearing threads in thin materials. Rivet nuts are ideal for tubing, extrusion, and similar applications.

  • Made from aluminum, brass, steel or stainless steelThread-Rivet-Nut-Group
  • Use in place of tapped holes, weld nuts, rivets, self-drilling & tapping screws
  • Only need access from “front” side of the workpiece
  • Provide strong permanent metal threads in metal or plastic materials
  • Can be installed in materials as thin as 0.020″ / 0.50mm
  • Help promote thinner and lighter product designs

Threaded Rivet Nut Classifications

Threaded rivets nuts can be classified into two basic groups – Standard Thread Rivet Nuts & Heavy-Duty Threaded Rivet Nuts

Standard Rivet Nuts: Are designed for most standard blind fastening applications that require permanently installed threads.

  • Available in unified and metric thread sizes #6-32 to 1/2″-16 and M4 thru M10

Heavy-Duty Rivet Nuts: Are designed for more demanding, high-performance blind fastening applications that require permanently installed threads. Heavy-duty rivet nuts feature heavy-duty head and sidewalls.

  • Available in unified and metric thread sizes #4-40 to 1/2″-13 and M3 thru M12

New Blind Rivet Lines

Blind rivets are designed for fastening materials together when you only have access to one side of the part or structure. Important factors you need to take into consideration when choosing the rivet for your next job include: grip range, shear strength & tensile strength.

  • Grip Range: the minimum and maximum thickness that the rivet is intended to hold together once installed.
  • Shear Strength: the maximum load that can typically be applied to the rivet that can be supported prior to failure and fracture.
  • Tensile Strength: the maximum tension applied load that can typically be applied to the rivet prior to failure and fracture.

My old bike

When I was young, I bought my first bicycle from a friend at the end of the block. It had been sitting in their backyard for a few months, and I don’t think I could describe all the things that were wrong with it.  To add to my dilemma, I didn’t have a tool box or wrench set to my name, and my Dad was in the habit of keeping his tool boxes locked, or hidden in the garage. Before the summer was over, I learned to repair almost anything on that ten dollar bicycle with a hammer, a pair of vice-grip pliers, and a large screw driver that I borrowed from Dad’s tool box when he wasn’t looking. I wasn’t very efficient, but at least I could change a flat tire, or adjust the seat and handlebars.

Unfortunately, the professional repair technician is often faced with the same dilemma when he is in the field. How often does a technician or contractor roll up on a job, and have the wrong tools and inadequate fasteners to complete a project efficiently, and with equipment that will stand the test of time?

As manufacturing moves away from one-size-fits-all approaches to the products they manufacturer, and becomes more segmented, specialty fasteners are becoming more common place. In the same way a contractor wants to have the right tool for the job, projects are becoming increasingly tied to having the right fastener as well as the right tools.

Rivets

Marson blind rivets are a perfect example of an older fastening device that has been redesigned for today’s construction industry. Standard rivets used in metal fabrication are short pieces of steel which are put through holes in two pieces of metal, and then both sides of the steel bar are pounded over into mushroom-shaped heads. The joint is reliable, and the metals pull themselves together.  However, when only one side of the material is available, a blind rivet is the perfect adaptation of this device.

A blind rivet features a hollow, soft metal sleeve with a stiffer shaft inserted into the center. The rivet is pushed into the holes in the fasteners and then anchored in place with a specialized tool. Once the blind rivet seats itself, the center shaft snaps off, leaving a strong metal-to-metal joint that is unaffected by vibration.  Some of these fasteners feature threaded rivets. Once the rivet is fastened in place, a machine screw or stove bolt can be inserted. This fastener is the perfect solution when a threaded hole is needed in a piece of sheet metal.

Torx plus security screw

The Torx head fastener is one of the most innovative products in the last 20 years, and now Torx head fasteners are used in manufacturing and assembly plants around the world. This fastener is perfectly suited as a security fastener, and with a small change, Torx pin head security screws allow technicians to install equipment in public places with assurance that neither their fasteners, nor their equipment will not be tampered with.

How To Measure a Blind Rivet

One of the most common questions we’re asked is, “How do you measure a rivet?”

Let’s use a common code description and break it down, we’ll use ABL6-8A as our example.

The first letter “A” indicates the rivet material. For instance, “A” for aluminum, “S” for steel, “C” for copper and “SS” for stainless steel.

The second letter tells us the head style, “B” for button head, “C” for countersunk.

If there’s a third letter in the description, it’ll be an “L” for large flange head.

The first number in the description is for body diameter, in 32nds.

The second number indicates maximum grip length in 16ths. Grip Range is the “working range” that the rivet can handle to meet the strengths designated in the IFI 114 Standards. Grip Range is not actual length. As a general rule, you would want to subtract 1/8″ off the length of the barrel for the barrel to be able to expand and lock the material together. So using your math skills and reducing 8/16″ to 1/2″ and subtracting 1/8″ you would have a grip range of 3/8″ and your rivet would have a size of 6-8.

The final letter is the mandrel (nail or stem} material. “A” for aluminum, “S” for stainless steel, “B” for brass, “C” for copper. No letter indicates a steel mandrel.

How a Blind Rivet Works?

blind rivetA blind rivet consists of two parts, a hollow, cylindrical body with a flared head and a solid-rod mandrel with a bulbed head that resembles a nail.

The body of the blind rivet is inserted in a hole in the materials to be joined or the blind rivet is placed into an installation tool, and then inserted into the application.

Activate the tool by squeezing the trigger in an air/hydraulic tool or the handles in a manual tool. The tool pulls the mandrel, drawing the mandrel head into the blind end of the rivet body. This action forms an upset head on the rivet body and securely clamps the application materials together.

The mandrel then reaches its predetermined break-load and will snap, with the spent portion of the mandrel breaking away and being removed from the “set” blind rivet.

Blind rivets are available in a range of body styles such as open, closed-end, and multi-grip, with head styles in button, countersunk and large flange and in materials such as aluminum, steel, copper, plastic and stainless steel.

Fast, easy-to-use blind rivets offer speed of assembly, consistent mechanical performance, and excellent installed appearance, making blind riveting a reliable and economical assembly method.

5 Tips for Using Blind Rivets Effectively

Fastening with blind rivets can be a cost-efficient method for fastening… some tips are

 

#1. The shear and tensile strength of the blind rivet selected and the number of blind rivets used in the application should equal or exceed the joint strength requirements.

#2. The blind rivet body material should be compatible with the materials to be joined to resist galvanic corrosion that may result in a reduction of joint strength. If dissimilar materials are widely separated on the galvanic chart, it is advisable to separate them with a dielectric material such as paint or other coatings.

#3. The total thickness of materials to be joined must be considered. Select the rivet “grip range” which includes the total thickness of materials to be joined.

#4. Use recommended hole sizes for each blind rivet. An undersized hole will not allow insertion of rivet body and an oversize hole may cause rivet failure, joint failure and could adversely affect rivet shear and tensile strengths.

#5. Various head styles are offered to accommodate different assembly needs. The most popular is the button head, whose lower-profile head is twice the diameter of the rivet body. This provides an adequate bearing surface for nearly all applications. The large flange rivet provides a greater bearing surface for fastening soft or brittle facing materials. The countersunk head rivet is available for applications where a flush appearance is required.

What are Rivet Nuts?

Rivet nuts are simple and reliable fasteners with internal threads that can be installed into thin materials such as panel, tube, extrusions, castings, plastics, and many other materials providing strong load-bearing threads. Once installed, the fastener remains captive to which a mating component can be attached using standard hardware.

Rivet nuts offer many benefits over nuts, bolts, weld nuts, self-tapping screws, and pressed inserts, primarily their faster assembly and lower installation costs. Rivet nuts are assembled “blind” from one side only, ideal for assembly of box, tube, extrusions, or closed sections. Rivet nut installation is very efficient by using easy-to-operate, inexpensive, lightweight hand tools or handheld powerful air/hydraulic setting tools. Rivet nuts install into a wide range of material thicknesses due to their wide grip range tolerance.

A rivet nut is applied strictly as a mechanical fastener with minimal deformation of the work-piece and no damage to pre-painted surface coatings. Installation is environmentally friendly and produces no harmful gasses, heat, dust or electromagnetic fields to affect workers.
