1. Descriptions:
Phillips truss head sheet metal screws with a self tapping thread patern that forms its own threads in the material it is being screwed into and is mainly used for attatching two pieces of metal together but also works great in wood and plexiglass because of the coarse thread
The low profile of the truss head gives a very clean appearance as well as offering a much larger than most surface area that is perfect for applications where there is a risk of a screw head pulling through a pilot hole and are commonly used in RV restoration
Made from stainless steel grade 18-8 which offers a high level of chemical and corrosion resistance that will out perform and out last all zinc plated fasteners for years with out the need to perform costly and time consuming maintenance; 18-8 stainless steel truss head sheet metal screws are a better choice than 410 self drilling screws in out door applications that will be visible because unlike 410 stainless with a high iron content these screws have a low iron content and will not rust or turn red
stainless steel sheet metal screws offer the corrosion resistance and strength that makes them the best choice for an application that is exposed to a wet or damp enviroment and will withstand the test of time

3. Features:
• Can be used in place of a pan head to cover larger diameter
clearance holes in pieces requiring extra play during assembly.
• A truss head screw has a relatively large diameter head, and an
especially low profile protruding above the surface of the material
to be fastened; the top surface is slightly domed
• Also known as mushroom head, oven head, or stove head
• Length is measured from under the head to the end of the fastener
A self-tapping screw is a screw that can tap its own hole as it is driven into the material.
Some self-tapping screws are also self-drilling, which means that, in addition to the tap-like flute in the leading threads, there is also a preliminary drill-like fluted tip that looks much like the tip of a center drill.
4. Applications:
Wafer head self-tapping screws are used for connecting thin metal plate (steel, saws, etc.) The first connection is to make a hole, and then put the self-tapping screws into the plate. Since the self-tapping screw thread is made with high hardness, so the sharp point can attack a threaded bottom. It is connected internally threaded to form a connection. The Self Tapping Metal Screws are widely used in machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, equipment, instruments and so on....
