Drywall Screws


Description :
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.



  • 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.
  • Less prone to getting pulled through the wood due to Bugle Head.
  • 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.

  • 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.

How to Install :

  • For the specified anchor size, select carbide or core drill bit with nominal diameter as listed below in Table.
  • Drill hole to depth listed below.
  • 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.


Suitable for :
