Truss head screws are generally weaker than any other type of screws, but they are preferred in applications requiring low clearance above the head. They can also be modified to reduce the clearance even further, while also increasing the surface of bearing.
Despite being comparatively low strength, they can still be used for metal-to-metal fastening. They can be drilled, tapped and fastened, all in one swift motion, saving the time and effort that you would have had to put in otherwise. They can be removed with the phillip head screwdriver. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant.
Truss head self-drilling screws for framing must be able to cut through heavy duty metal studs. They have special heads designed to decrease driving torque but have exceptional holding strength. They are capable of driving through metals of up to 0.125 inches thick with an RPM rate of 1500. They come in a variety of metals to fit the operation and application.
Regardless of if the material to be drilled is metal lathe or heavy gauge metal (between 12 to 20 gauge), self-drilling screws can easily connect and frame a structure.
