This Würth #10 x 2-1/2 inch washer head installation screw is designed for cabinet installation, face frame attachment to boxes, and fastening through layered stock where reach matters. The Phillips/square combination drive and coarse thread make it a workhorse for shops and installers who drive screws all day.
The 2-1/2 inch length is well matched to situations where you are driving through one layer of material and threading into a second. Attaching a cabinet box to a wall cleat, fastening through a face frame into a deeper panel, or pulling together two pieces of 3/4-inch sheet goods — these are the jobs where this length lands cleanly without bottoming out or leaving thread exposed. The washer head sits flush against the surface without requiring a countersink operation, which keeps installation moving on jobs where appearance at the fastener is secondary to speed and strength.
The Phillips/square combination recess is designed to hold the screw on a correctly sized bit for one-handed placement, which matters when you are reaching into a cabinet box or driving overhead. Coarse thread provides strong pull-out resistance in the wood-based substrates common in cabinetry: plywood, particleboard, MDF, and solid lumber. The zinc finish is for indoor work in dry environments. For exterior or pressure-treated applications, a coating rated for those conditions is the right call.
Cabinet installers putting boxes on walls, shops assembling and hanging face frames, and finish carpenters fastening through multiple layers are the natural buyers here. The 1,500-count box suits crews that go through installation screws in volume and do not want to stop mid-job to restock. The combination drive is especially practical in environments where both Phillips and square bits are in rotation — no need to change bits or hunt for the right one when the driver is already in your hand.
No. The washer head is a non-countersunk head that bears against the surface, so no countersink is needed. It will sit proud of the surface by the height of the head.
The combination recess accepts a #2 Phillips bit or a #2 square bit. Either works in the same head, so you can use whichever is already loaded in your driver.
The zinc finish is rated for dry indoor environments. For exterior applications or pressure-treated lumber, choose a screw with a coating rated for those conditions.
The sharp point self-starts in softwoods, plywood, and sheet goods reliably. In dense hardwoods, a pilot hole helps prevent splitting and makes driving easier.
Installation screws are general-purpose wood screws with a head and thread combination suited to cabinet and millwork installation — attaching boxes, frames, and components where a broad bearing head and strong pull-out resistance matter.
When the work calls for driving through one layer and pulling firmly into a second, the 2-1/2 inch length gives you the reach to make that connection cleanly — and a box of 1,500 means you will not run short on a full-day install.
