1. Self Drilling Self Tapping Screws
Self drilling self tapping screws differ in the purpose where it is being used. Self
drilling screws are similar to metal screws with threads but in addition it has a
drill like tip, and then the thread starts to the top. This goes into the metal sheets
and hard objects like a drill which eliminates the need for doing a pilot hole. The
self drilling screws are very efficient in hard substrate applications from roofing to
assembly line.
Whereas self tapping screw is where it can find its way inside the meta l or hard
object as it is turned in its place. There is a small drill like point in the front and
then as it advances into the metal it can cut its own thread. This is made by
creating a groove running all the way from bottom to the top. This thread drills
through the material causing the screw to move inside the metal or hard surface.
More Stylish Shades Are Available From the Solid Polycarbonate Sheets Range
Polycarbonate sheets are made of thermoplastic polymers and can be worked,
moulded and thermoformed. They are preferred over glass sheets because they
can prevent UV rays from passing. They also have strong resistance and are 200
times stronger than common glass. For this reason they are preferred as roofs on
top of the building for entertainment venue where light is needed to pass. These
solid polycarbonate sheets are so light that they weigh almost half of the glass for
the same volume. When it is used as walls or roofs, the advantage it gives is the
thermal insulation. It is a bad thermal conductor so keeps the heat away from

2. passing across while at the same time gives light. The use of self drilling self
tapping screws during the installation of these sheets makes the roofing even
more durable.Visit site
