This Würth #8 x 7/8" truss head machine screw is built for attaching cabinet knobs, pulls, and decorative hardware where minimal panel thickness or a low-profile fastener is the priority. The 8-32 fine thread is the North American cabinet hardware standard, ensuring a reliable fit with virtually any knob or pull in production or one-at-a-time installation work.
Most cabinet hardware screws are sold in 1 inch or longer, which works well for standard 3/4-inch panels with room to spare. The 7/8-inch length fits the situations where that extra thread engagement is not available or not wanted: thin drawer fronts, overlay doors on thin-wall frameless boxes, or hardware with a deep base that already consumes some of the available panel depth. The truss head's wide bearing flange keeps the hardware pulled flat against the face without needing a recessed countersink, which matters when the hardware base is flat or when countersinking is not practical.
The truss head sits above the surface with a broad, low dome that spreads clamping force evenly across the hardware mounting plate. This is the right head choice when the hardware back plate or mounting boss needs full-face contact rather than a countersunk pocket. Fine thread on an 8-32 body means the pitch is matched to the pre-tapped threads found in standard cabinet knobs and pulls across every major hardware brand. The zinc plating is a standard interior finish, appropriate for the dry conditions inside cabinet doors and drawer fronts. These screws are for indoor cabinetry; if the application involves a wet or exterior environment, a corrosion-resistant finish is the right call instead.
Cabinet installers and finish carpenters who stock a range of hardware screw lengths keep 7/8-inch on hand for thin-profile situations that come up regularly on kitchen and bath jobs. Hardware specifiers sourcing for custom furniture or commercial millwork projects sometimes need a shorter screw to match a specific panel thickness or hardware depth. For shop production, a box of 100 covers a focused hardware run without over-ordering for a single job.
When the panel is thin, the hardware base is deep, or a protruding screw tip inside the cabinet is a problem, 7/8 inch gives you full thread engagement with less material penetration. A 1 inch screw in the same situation may poke through or bottom out before the hardware seats.
The truss head has a wider, flatter bearing flange than a standard pan head. That extra width distributes clamping load across a larger area of the hardware base, which helps keep flat-back hardware pulled evenly against the door or drawer face.
Yes. The 8-32 thread is the North American standard for decorative cabinet hardware, so it is compatible with knobs and pulls from virtually every hardware manufacturer that follows that standard.
Yes. The combination recess accepts a #2 Phillips driver or a flat-blade driver in the same head, so either works depending on what is on hand.
No. The zinc finish is rated for dry indoor conditions. Exterior applications or high-humidity environments call for a screw with a corrosion-resistant coating rated for that exposure.
When a 1 inch screw is one thread too many for the panel in front of you, the Würth 7/8-inch 8-32 truss head machine screw gives you the same standard thread and broad bearing surface in a length that fits the job without modification.
