This Würth #8 x 5/8" truss head machine screw is a compact 8-32 fine thread fastener for mounting cabinet knobs, pulls, and decorative hardware where panel depth is shallow or hardware backing is thin. The extra-wide truss head distributes clamping load over a larger bearing surface than a standard pan head, and the combination Phillips/slotted drive keeps it compatible with the most common bits on the bench or at the job site.
At 5/8", this is one of the shorter lengths in the 8-32 machine screw range, and that is the point. Thin drawer fronts, narrow stile sections, shallow-backed knobs, and hardware that sits close to the panel face all benefit from a shorter screw that reaches the hardware thread without bottoming out or passing through the front face. It is a natural choice for flat cabinet doors, thin-profile drawer fronts, and cases where the standard 1" or longer screw leaves too much unengaged thread or risks showing through the face. Cabinet shops and installers who work with a range of door thicknesses tend to keep both short and long 8-32 screws on hand; the 5/8" handles the thinner stock.
The truss head carries a wider footprint than a pan or flat head, making it a practical choice when the hardware mounting hole is slightly oversized or when the bearing surface behind the hardware is limited. It sits low after seating, with no sharp edge that would press into a finish surface. The combination Phillips/slotted recess means a #2 Phillips driver handles power-tool installation while a flat-blade works for hand-tightening or field service where a Phillips bit is not available. Neither drive is exotic, so the screw moves fast in any shop or on any job site.
An 8-32 machine screw serves one primary job in the cabinet and woodworking trade: attaching knobs, pulls, cup pulls, and bar handles to door faces and drawer fronts. The 8-32 thread is the industry default for North American cabinet hardware, so this screw drops into the pre-tapped holes on standard hardware without any thread matching or adapter. Cabinet shops running high-volume finishing, millwork operations installing hardware across a large project, and contractors hanging production-built cabinetry all go through these in quantity. The 1000-piece box supports that pace. The zinc finish is for interior, dry environments; this screw is not suited to outdoor hardware or wet-area applications.
The truss head has a wider bearing diameter and a lower profile than a pan head. When the hardware mounting hole is larger than the screw shank, the wider head spans it cleanly. The lower profile also leaves a neater appearance when the head is visible inside a cabinet or behind a pull.
Yes. The 8-32 thread is the North American standard for cabinet hardware, so it is compatible with virtually all knobs and pulls that accept a standard mounting screw. Always confirm the thread specification on any imported or metric hardware before ordering.
The combination recess accepts a #2 Phillips bit or a standard flat-blade bit. Either works in the same head without a separate screw version.
Match screw length to the combined thickness of the panel and hardware backing. For thin drawer fronts, flat-profile doors, or hardware with a shallow internal thread, the 5/8" length keeps the screw engaged without passing through the face. If the door or drawer front is thicker, a longer length in this family will likely be a better fit.
No. The zinc finish is rated for dry interior use. For exterior hardware or high-humidity environments, a stainless steel or coated fastener with appropriate corrosion resistance is the right call.
When thin panels and shallow hardware call for a compact fastener with a wide bearing head, this 5/8" zinc truss head machine screw keeps the hardware seated cleanly, the head low, and the installation moving at production speed.
