Product Characteristic & Use

Wafer head self drilling screw features a sharp point and cutting threads that provide excellent retention in wood, composites, plastics, and soft metals. They are made of grade 304 Stainless Steel, which is corrosion and rust-resistant.

Modified Truss Head Screws feature an oversized domed head with a flange, similar to an integral washer. Modified Truss Head Screws have a 100-degree undercut which creates a larger area beneath the screw’s head for a larger bearing surface.

Phillips Modified Truss Head Sheet Metal Screws (also known as Lath Screws) features a Phillips drive and a notched type 17 point at the tip to aid in chip removal during thread cutting.

1. Larger head provides a larger bearing surface area for attaching metal lath.
2. Low profile head meets installation requirements for attaching metal lath to wood or steel.
3. Available with Type 17 or #3 self-drilling point.
4. Type 17 points for fast starts and minimized splitting.
5. #3 self-drilling point penetrates steel up to .142″ thick.
