A carriage bolt is used to fasten metal to metal, wood to wood, and wood to metal. The head of a carriage bolt is round with a square neck under the head. The square neck functions as a locking device when inserted into a pre-drilled hole, designed to keep the head from turning as a nut is tightened. Carriage bolts can be manufactured from low and medium carbon steel, as well as stainless steel.

Tanner Bolt & Nut Corp. features seven types of security fasteners with unique drive configurations, each available in different head styles and materials. Security fasteners are cap screws, machine screws, self-drilling screws, concrete screws, sheet metal screws, nuts, or bolts manufactured with a tamper-proof or tamper-resistant drive or head style. Installation tools are available.

Hex bolts, also known as hexagonal head bolts, are threaded machine bolts used with a nut or in a tapped hole. As the name suggests, hex head bolts are hexagonal heads (6 sides) made from grade 2 galvanized steel, 316/304 stainless steel, and grade 5 zinc plated steel.

Hex head bolts are designed to secure objects within or against other objects for a non-loosening hold. Applications for a hex bolt include fastening steel to steel, wood to wood, and other materials found on construction for

Fastening materials to metal is commonplace on the job site.

However, this means that you’ll need a special type of screw to get the job done: Self-drilling screws for metal. 

We’ll cover what you need to know about self-drilling screws for metal below. But first, let’s talk about the differences between screws for metal and other materials.

Self-drilling screws, like the name suggests, are screws that drill their own holes, the installer doesn’t need to drill a pilot hole. Self-drilling screws are sometimes confused with self-tapping screws. A self-tapping screw is a sheet metal screw. The difference is self-tapping screws are installed into pre-punched or pre-drilled holes. 

Self-drilling screws should be installed using a variable speed screw gun, (not an impact driver) like the DeWALT DCF622M2 RPMs are critical when driving

Self-tapping screws are a common type of fastener used on the job site that can make your life easier. When used correctly, they can save you time and a potential headache when fastening materials.

At Tanner, we offer nothing but the best products to our customers. From simple screws to security hardware, everything we sell is top-notch quality. 

That includes our wide range of expansion anchors.

We’re not just talking about any expansion anchors here, though. These are Power-Stud®+ Wedge Expansion Anchors from Dewalt engineered by Powers Fasteners®. These anchors are fully-threaded, torque-controlled, and designed for consistent performance in both cracked and uncracked concrete. 

Self-tapping screws and self-drilling screws are two of the most common types of fasteners. Both types of screws are heavily used in general construction, especially when it comes to metal fastening.

However, the differences between self-drilling screws and self-tapping screws can sometimes fly under the radar. 

Let’s dive into self-drilling screws and self-tapping screws, how they work, and their individual use cases. 

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
