Metallics WDW2B 8 x 3/4 in. Wafer Head Phillips Sharp Point Drywall Screws - Steel Zinc - Each

The WDW2B ships as a box of 10,000 screws, and that is also the order minimum (10,000 each). It is a bulk fastener line, not a contractor pack, so plan it as a stocking buy for an electrical or mechanical crew rather than a single job pickup. The boxed quantity weighs 45.98 lbs.

The WDW2B is a self-piercing and tapping sharp point screw, so it pierces and forms its own thread in light gauge steel studs and track without a pilot hole. For heavier structural steel a self-drilling (drill point) screw is the right call instead. The 3/4 in. length suits single layer board on light gauge framing, where you only need enough thread past the stud face to hold.

No. The WDW2B is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic sourcing requirement, this fastener will not satisfy it and you need a domestically produced screw.

A wafer head sits low and spreads load over a large bearing surface, which is why these are used to fasten sheet goods, straps, brackets and clips rather than just to dimple paper face board. Head width runs 0.426 to 0.446 in. with a head height of 0.082 to 0.098 in. If you need the head to pull fully below the paper for taping, a bugle head drywall screw is the better pick.

A #2 Phillips. Three power bits come in the box with the screws, so a crew can start driving without sourcing bits separately. Recommended driving torque is 45 Kg/cm minimum, so a standard screwgun or impact driver with a clutch handles them fine.

The WDW2B is steel with a zinc finish, which is an interior-duty coating. Use it for dry interior work such as framing accessories, strap and bracket mounting, and board fastening. For exterior exposure, wet locations, or contact with treated lumber, specify a coated or stainless fastener instead.

The screws are made from AISI 1018 to 1022 steel, case hardened to Rockwell C28-38, and rated to 45 Kg/cm minimum torque. That hardness range is what lets the sharp point tap its own thread in light gauge steel without the tip rolling over, while keeping enough core toughness to resist snapping at the shank.

Metallics lists the WDW2B for the electrical, plumbing, heating and air conditioning trades. In practice that means mounting straps, hangers, clips, plates and sheet goods to light gauge steel studs and track, where the low profile wafer head keeps clearance tight behind board or equipment.

The WDW series is offered in other sizes and quantities by request; the WDW2B specifically is the #8 x 3/4 in. configuration. One caution when matching sizes: there is no single industry standard for self-piercing screw dimensions, so the published head and length figures are a guide and small deviations can occur.
