Metallics DWSR1M 6 x 1 in. Bugle Head Square Drywall Screws - Steel Black Phosphate - Coarse Threads - Each

No, not reliably. The DWSR1M has a sharp point and coarse threads, which is the wood framing combination. Light gauge steel studs call for a fine thread (high low or S point) drywall screw that cuts rather than wedges. Using a coarse sharp point screw on steel studs tends to spin the stud or strip out.

A #1 square (Robertson) bit. The recess is a square drive sized 0.090 to 0.106 inch wide and 0.055 to 0.071 inch deep, and Metallics calls out a #1 driver. If your crew is running Phillips #2 bits on a collated gun, you will need to swap bits before you start.

No. Black phosphate is a dry interior finish with minimal corrosion resistance, and these screws are supplied with that finish on steel. Keep them inside for drywall on wood framing. For exterior sheathing, soffits, or anywhere that sees moisture, use a coated or galvanized exterior screw instead, or the screw heads will rust and bleed through your finish.

The square recess on the DWSR1M resists cam-out, so the bit stays seated when you are driving overhead or at an angle and you get fewer torn paper faces from a slipped bit. Phillips is still the more common drywall head and is what most collated systems and spare bits are set up for. If you are hand driving with a drill or impact, square drive is the easier of the two to control.

That is what the bugle head is for. The head on this screw measures 0.315 to 0.347 inch across with a head height of only 0.020 to 0.031 inch, so the curved underside compresses the paper and seats just below the surface for an easy mud coat instead of punching through. Set your screw gun depth so the head dimples the board rather than breaking the face.

These ship 1,000 screws per jar, and 1,000 is the order minimum. A full jar weighs 3.47 lbs. Other sizes and quantities of the DWSR series are available by request.

The DWSR1M is AISI 1018 steel heat treated to Rockwell C45-64, which is the normal case hardness range for drywall screws. That is hard enough to drive into wood framing without stripping the recess, but it also means the screw is brittle in shear, so these are a fastener for hanging board, not for structural or load bearing connections.

No. The DWSR1M is listed as not Buy American compliant and not ARRA compliant, with country of origin recorded as multiple. If your contract carries a domestic sourcing clause, this is not the screw to spec.

8 to 10 threads per inch, UNC coarse spacing. The wide pitch is what pulls the screw into wood fast and gives it grip in soft framing lumber. Drywall screw dimensions are not governed by a single industry standard, so Metallics publishes these as a guide and slight deviations are normal.
