Metallics WDS4B – Frequently Asked Questions

1) Will the Metallics WDS4B #8 drywall screw drill its own hole through metal studs, or do I need to pre-drill?
No pre-drilling. The WDS4B is a Type BSD self-drilling and tapping screw with a drill point, so it cuts through the stud flange as it goes. Metallics rates drill time at 2.5 seconds through a 1 mm thick plate.
2) What gauge metal stud will a #8 x 1-1/4 in. Metallics WDS self-drilling screw go through?
The WDS4B is specified for panel thickness in the 0.350 to 0.100 in. range, which covers the light to medium gauge steel framing used in commercial drywall and for electrical, plumbing and HVAC metal-to-metal work. It is a metal-to-metal fastener, not a wood screw.
3) Can I use Metallics WDS4B screws on a federally funded or Buy American project?
No. The WDS4B is reported as not Buy American compliant and not ARRA compliant, with multiple countries of origin. If your contract carries a domestic sourcing clause, you need a domestically manufactured self-drilling screw instead.
4) What driver bit do I need for Metallics WDS4B wafer head screws?
A #2 Phillips bit. The recess is a Phillips drive measuring 0.176 to 0.189 in. diameter at 0.255 in. depth, so a #2 seats fully. Three power bits ship with the order.
5) Why use a wafer head screw instead of a bugle head for hanging panels on metal framing?
A wafer head spreads load over a wider, flatter bearing surface, which is what you want when fastening thin sheet or furring to steel rather than countersinking into gypsum face paper. The WDS4B head measures 0.359 to 0.38 in. across with a head thickness of 0.025 to 0.035 in., so it sits low. Bear in mind there is no single industry standard for wafer head dimensions, so those figures are a guide.
6) Will Metallics WDS4B screws snap when driven with a high-torque screw gun?
They are rated to 42 lb-in minimum torsional strength and heat treated to Rockwell C32-40, which is what lets the point cut steel without the shank twisting off. Set your gun clutch and let the drill point do the work rather than leaning on it.
7) Are Metallics WDS4B screws suitable for exterior or damp locations?
These are carbon steel with a zinc finish, drawn from AISI 1016 to 1024 steel. Zinc plating is an interior-duty coating, so keep them to dry interior framing and mechanical rough-in work. For wet or exterior exposure, specify a stainless or coated exterior self-drilling screw instead.
8) What is the minimum order quantity on Metallics WDS4B drywall screws?
10,000 each, supplied in a box. That is a bulk production quantity aimed at contractors running a full job or MRO stock, not a counter pack. The box is listed at 70 lbs with carton dimensions of 9 x 9 x 6.13 in.
9) What thread does the Metallics WDS4B #8 screw have, and will it hold in thin sheet steel?
18 threads per inch, UNF, to the SAE J78 2013 self-drilling tapping screw standard. The fine pitch is what gives you engagement in thin steel flange, where a coarse drywall thread would strip.
10) Does Metallics offer the WDS series in lengths other than 1-1/4 in.?
Yes. The WDS wafer head self-drilling family runs in other diameters, lengths and pack quantities by request; the WDS4B is the #8 by 1-1/4 in. configuration.
