Coarse Or Fine Thread Philips Drive Bugle Head Drywall Screws 18 - 8 3.5 X 50mm DIN18182
1. Descriptions:
Drywall Screw is a specialized self-tapping screw with a
cylindrical shaft. These screws almost always have a Phillips Bulge
Head rather than a slotted head, which provides additional control
for installers. In addition of a standard drill, installers also
use a tool known as a drywall dimpler, which has an adjustable nose
to install a drywall screw without tearing the paper on each sheet.
A standard drywall screw can be
readily identified by its black finish. This black coloring comes
from a phosphate mineral coating that is applied to these screws.
This coating helps to minimize rusting and corrosion as the screws
are exposed to wet joint compound or paint.
We are factory to produce many kinds of screws for more than 15 years, every month we can ship 15-20 containers to the world market....
