This Würth #8 x 1-3/8 inch truss head machine screw is built for attaching cabinet knobs and pulls where a standard-length screw comes up short. The 8-32 thread is the North American cabinet-hardware standard, so it fits virtually any knob, pull, or bar handle without guesswork. A Phillips/slotted combination drive means installation works with whichever bit is on hand, and the zinc finish suits dry indoor cabinetry work.
Most cabinet hardware ships with 1 inch machine screws, which work well through a single layer of 3/4 inch material. When the door or drawer front is thicker, built up with a secondary panel, or backed with a reinforcement plate, that length runs out of thread before the hardware seats. The 1-3/8 inch length closes that gap. It threads fully through the panel and into the hardware post without bottoming out or pulling the fastener into a bind. For shops building slab fronts from double-layer stock, frameless doors with solid-wood overlays, or any installation where the measured stack exceeds an inch, this length is the direct answer.
The truss head sits flat against the cabinet interior or mounting surface and spreads its clamping load over a wide footprint. That broad bearing surface matters when the mounting hole in the cabinet panel is slightly oversized or when the hardware backing plate has a large clearance hole. There is no countersink required, and the head will not pull through typical panel materials under normal hardware-mounting loads. The zinc-plated steel construction is appropriate for interior cabinetry in standard indoor conditions. This screw is for dry, inside-the-cabinet work.
Keeping a box of 1-3/8 inch 8-32 screws on hand solves a specific, recurring problem: a knob or pull that cannot be fully seated with the screws that came in the hardware bag. For a cabinet shop running production, having the right length already in stock eliminates the mid-install scramble. For a contractor or finish carpenter, the 1000-piece box covers an entire kitchen run without reordering. The Phillips/slotted drive means any installer with a standard bit set can complete the job.
When cabinet doors or drawer fronts exceed a standard 3/4 inch thickness, either from built-up construction or added backing, a 1 inch screw may not fully engage the hardware post. The 1-3/8 inch length provides the additional reach to thread completely through thicker stock and seat the hardware securely.
Yes. The 8-32 thread is the North American cabinet-hardware industry standard. Knobs, pulls, cup pulls, bar handles, and bin pulls from virtually all major hardware brands use 8-32 machine screws as their mounting fastener.
A truss head is extra-wide and low-profile, providing more bearing surface than a pan head. That wider footprint distributes clamping load over a larger area, which is useful when the clearance hole in the panel or mounting plate is larger than the screw shank.
The combination recess accepts either a #2 Phillips bit or a flat-blade driver. Most installers drive these with a #2 Phillips. The flat-blade slot is there as a backup if the Phillips driver is not available or if access is limited.
No. The zinc finish on this screw is rated for indoor, dry environments. For exterior hardware mounting or any installation exposed to moisture, a stainless or coated fastener is the right choice.
When hardware specs call for more reach than a standard machine screw provides, the Würth #8 x 1-3/8 inch truss head is the straightforward solution, packed 1000 to the box so production shops and working installers stay stocked through an entire project.
