Small White Truss Head Wafer Head Machine Screws With Sharp Point #
8 X 1/2 Modified
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....
