Metallics WDW4M – Frequently Asked Questions

1) Do the Metallics WDW4M drywall screws come in a box of 1000, or can I buy them individually?
The WDW4M ships as a box of 1000 screws. The order minimum is 1000 pieces, packed in a box, so this is a bulk buy rather than a handful at the counter. The box weighs 6.22 lbs.
2) Will a wafer head screw sit flush enough to run conduit strap or a bracket over it?
That's the point of the wafer head. The head measures 0.426 to 0.446 in. across with a head height of only 0.082 to 0.098 in., so it keeps a low profile while spreading load over a large bearing surface. Handy where something has to mount over the fastener rather than a countersunk bugle head pulling through thin material.
3) Are sharp point drywall screws right for steel studs, or do I need self-drilling?
The WDW4M is a sharp point, self-piercing and self-tapping screw. Sharp point works in wood framing and light gauge steel stud where the tip can pierce the metal on its own. Heavier gauge steel is where you move to a drill point screw instead, because a sharp point will just spin and walk.
4) What driver bit do I need for these wafer head Phillips drywall screws?
A #2 Phillips bit. The WDW4M uses a Phillips drive, and a free power bit is included in the box, so you are not hunting for one on the first day of the job.
5) What size screw is the Metallics WDW4M?
It's a #8 diameter by 1-1/4 in. long screw with a UNF thread. That length is the common pick for single layer board over framing, giving enough embedment past the panel without blowing through the back of light material.
6) How tough are these screws? I keep snapping heads off with an impact driver.
The WDW4M is heat treated to Rockwell C28-38 with a minimum torsional rating of 45 Kg/cm, made from AISI 1018 to 1022 steel. That said, torque-limiting matters more than the screw: a screw gun with a depth-sensitive nose is the right tool for board work, not a full-power impact.
7) Are zinc plated drywall screws OK for exterior or damp locations?
These are steel with a zinc finish, which is a light corrosion coating meant for dry interior work. For exterior, wet, or treated lumber applications, zinc plating is not enough and you want a hot dip galvanized or stainless fastener instead.
8) Do these Metallics screws qualify for a Buy American or ARRA job?
No. The WDW4M is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic sourcing requirements, you will need a different fastener.
9) Is this screw only for drywall, or can electrical and mechanical trades use it?
Metallics lists the WDW4M for the electrical, plumbing, heating and air conditioning trades. Electricians use wafer head sharp point screws for mounting brackets, straps, and light fixtures to framing, not just for hanging board.
10) Can I get this WDW series screw in a different length or pack quantity?
The WDW series runs other diameters and lengths beyond the 8 x 1-1/4 in. WDW4M, and other quantities are available by request. Also worth knowing: there is no single industry standard for self-piercing screw dimensions, so the head and point figures published for these are a guide and small deviations happen batch to batch.
