Self-drilling screws feature a drill-shaped point that enables them to drill their own pilot holes in materials such as sheet metal, wood, and plastics without requiring pre-drilling.
Modified Truss Head screws have a wider, lower-profile head structure which offers a larger surface area to secure metal components without tearing or warping the surrounding sheet metal.
Yes. Stainless steel self-drilling screws are highly resistant to oxidation, corrosion, and rust, making them ideal for outdoor installations, marine applications, and humid environments.
Phillips drive has a standard cross shape suitable for common tools. Square drive offers a deeper, tighter contact fit with the driver bit, which minimizes cam-out and slippage under high torque.
No pre-drilling is necessary as the screw tip acts as a drill bit. However, depending on the hardness of the material, a matching countersunk indentation may help the screw head sit perfectly flush.
