Truss head self drilling screw-1 inch

Product Description

The #8 x 1 inch self-drilling screw with a modified truss head is a high-performance fastener. It is engineered for efficiency and reliability in demanding construction and assembly tasks.

This screw combines a #2 drill point with self-tapping threads. It allows it to drill, tap, and fasten in a single operation. This significantly reduces labor and installation time compared to traditional screws.

The defining feature is the modified truss head, which has a low, wide profile. This design provides a large bearing surface for excellent holding power. It also creates a sleek, finished appearance, making it ideal for applications where a snag-free, flush surface is desired.

This head style combines the protective function of a flat washer with a low profile aesthetic.

This screw is a type of TEK screw, an industry-standard term for a self-drilling fastener. It is most commonly manufactured from zinc-plated carbon steel. This offers a great balance of strength and cost-effectiveness with good corrosion resistance for interior use.

Whether installing metal lath for stucco, assembling HVAC ductwork, or securing steel stud framing, this screw provides a reliable and professional solution.

What is the difference between a Modified Truss Head and a standard Truss Head?

The design of the modified truss head is a key question.

A standard truss head has a wide, low profile. However, the modified version has an even wider and lower profile. This extremely low profile makes it perfect for applications where minimal clearance above the head is required. It is also ideal when a very flat surface is needed to avoid snagging on clothing or materials. The modified truss head allows for better concealment.

How does a self-drilling screw work, and what’s the advantage?

This is the core function of the screw.

Unlike a standard screw that needs a pre-drilled pilot hole, a self-drilling screw has a drill point at its tip. As the screw is driven in, this point drills the hole. The threads immediately follow to create a tight, secure hold in the material.

This eliminates a separate step, saving time and tooling costs. These screws are described as having a self-drilling point enabling it to drill its own hole in thin sheet metal, heavier gauge metals, and other materials.

What materials can I fasten with a #8 x 1 inch self-drilling screw?

This size is incredibly versatile. It is designed for light to medium-duty metal fastening applications.

Common uses include attaching metal lath to wood or steel studs for stucco and plaster applications. It is used for securing HVAC ductwork, ducts, vents, and components to structural supports.

It is used for fastening electrical boxes, conduit straps, and metal framing members. It is suitable for general metal-to-metal and metal-to-wood projects, such as attaching brackets. It is also used for steel stud framing, including fastening studs to track.

What is the correct driver bit to use?

These screws feature a Phillips drive, which is a widely used cross-shaped drive system.

For this #8 size screw, you should use a #2 Phillips bit. Using the correct bit size is crucial to prevent stripping the screw head during installation. Some similar fasteners may feature a square drive, but the Phillips drive is standard for this type.

What sizes and packaging options are available?

This screw is typically available in various package quantities to suit different project scales.
