DRYWALL SCREW
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.
FEATURES
APPLICATIONS
INSTALLATION GUIDE
The primary benefit offered by drywall screws is their Bugle Head. This means that the entire screw lies flush with the surface of the sheet, creating a smooth and even finish.
This type of head also helps prevent the drywall screw from breaking the paper surface, a common problem with nails.
Drives fast and efficient.
The black head adds to the decorative appeal.
Fairly thin, so they are less likely to split the wood.
Threaded through entire length thereby maximizing gripping power.
Good Corrosion resistance due to black phosphate coating.
Easy to install and remove.
Head does not sink into the wood easily as does with other wood screws.
Precise cutting edges to improve drill performance with less effort.
Relatively Cheap.
At least 3 times the pull-out strength of nails.
Less prone to getting pulled through the wood due to Bugle Head.
Original and primary application is to stitch Drywall to wood studs. Also used in many interior wood and fixture fastening applications.
Used to rapidly attach drywall to metal studs for commercial buildings.
Used where flat surface required after drill.
Used where already pre-drilled holes are prepared for fitting.
For the specified anchor size, select carbide or core drill bit with nominal diameter as listed below in Table.
Essentially clean holes with brush and blower.
Remove debris with hole cleaning pump, compressed air or with a brush.
If the holes are wet or flooded, clean hole with brush.
Insert Capsule into hole.
Spin in Welfast Stud as per required anchorage depth using a rotary hammer drill.
Allow adhesive to cure for the time as listed below.
When cured, tighten nut applying the necessary tightening torque.
Drill hole to depth listed below.
