This Würth #8 x 1/2" truss head machine screw is built for attaching cabinet knobs, pulls, and decorative hardware to doors and drawer fronts where a low-profile head and shallow installation depth are the priority. The 8-32 thread is the North American cabinet-hardware standard, so it mates directly with the threaded bases of virtually all knobs and pulls without adapters or sizing guesswork.
At 1/2", this screw is sized for installations where minimal through-panel depth is available, such as thin drawer fronts, overlay doors with limited clearance, or hardware plates that sit close to the face surface. The short shank threads fully into a standard knob or pull base without bottoming out in shallow-set hardware, making it a practical choice when a longer screw would over-penetrate or interfere with interior components. It also suits hardware backing plates and mounting clips that call for a short fastener to avoid breaking through the panel face.
The truss head on this screw has a wider-than-standard diameter with a low, flat-top profile. That geometry distributes clamping load across a larger footprint than a pan or flat head of the same gauge, which helps the screw pull hardware plates snug against the surface without concentrating stress at the fastener hole. The combination Phillips/Slotted drive means a #2 Phillips bit handles the bulk of production driving, while the slotted option is there when only a flat-blade driver is available for touch-up or field adjustment. The zinc finish is appropriate for dry interior environments including cabinet interiors, frameless and face-frame boxes, and furniture applications.
The 8-32 thread standard is used across nearly every North American knob and pull manufacturer, so this screw slots into standard hardware without thread-matching or re-tapping. Shops running hardware installation on multiple boxes will find the 1000-piece count supports a full project run without mid-job restocking. For contractors and installers working with varied drawer-front thicknesses, the 1/2" length pairs cleanly with hardware designed for thin-panel applications, eliminating the need to keep multiple lengths on hand for shallow installs.
The 8-32 designation — #8 gauge at 32 threads per inch — is the thread specification adopted across virtually all North American cabinet hardware manufacturers for knobs and pulls. Because it is consistent across brands, a single screw size fits most standard knobs and pulls without needing to match threads to individual hardware lines.
A truss head has a larger-diameter bearing surface and a lower profile than a pan head at the same gauge. The wider footprint distributes clamping force over more area when pulling hardware against a door or drawer face, which can be useful where hardware plates have oversized or slotted mounting holes.
Yes. The drive accepts a #2 Phillips bit for powered or hand installation. The slotted recess is also present in the same head for use when a flat-blade driver is the only option available.
The zinc finish on this screw is intended for dry indoor environments. For exterior hardware mounting, a screw with a heavier corrosion-resistant coating is the better choice.
Machine screws require a pre-tapped hole or nut to engage threads. Standard cabinet knobs and pulls have pre-tapped bases that accept 8-32 screws directly, so no separate nut is needed for most hardware installations.
When the install calls for a short machine screw that threads into standard cabinet hardware without over-penetrating thin stock, the Würth 1/2" 8-32 truss head in zinc delivers a reliable, hardware-compatible fit for the job.
