This Würth #8-32 truss head machine screw is built for mounting cabinet knobs, pulls, and decorative hardware to door and drawer fronts where extra material thickness calls for a longer reach. The 8-32 thread is the North American standard for cabinet hardware, making this screw a direct fit for virtually any knob or pull without thread-matching guesswork.
Standard knob and pull machine screws run 1 inch to 1-1/4 inches for single-layer 3/4-inch stock. The 1-5/8 inch length covers situations where that standard falls short: a thick slab drawer front, a furniture-style door with applied molding, a double-layer panel, or a retrofit where the original shorter screw no longer reaches the hardware thread. Cabinet shops specifying hardware on doors over 1 inch thick will find this length eliminates the need to source custom hardware or use washers to close a gap.
The truss head carries a wider diameter than a pan or flat head, spreading the clamping load across a larger footprint beneath the hardware mounting plate. That matters when hardware backplates have oversized clearance holes or when repeated removal and reinstallation have slightly enlarged the opening. The Phillips/Slotted recess accepts a #2 Phillips bit for powered installation and a flat-blade for hand-tightening or field adjustments, so the same screw works whether a drill driver or a simple screwdriver is on hand.
Cabinet shops building furniture-style or thick-profile cabinetry keep this length stocked alongside standard 1-inch and 1-1/4-inch screws to handle the occasional deeper installation without a separate order. Hardware specifiers and designers working on thick slab doors or layered panel designs will want to confirm length requirements before the installer arrives on site. Homeowners replacing hardware on older or thicker cabinet doors often find the standard short screw supplied with new hardware does not reach, and this length resolves that without modification.
8-32 is the North American industry standard thread for decorative cabinet hardware. Nearly all knobs, pulls, cup pulls, and bar handles sold for cabinet use are tapped to this thread, so an 8-32 screw fits without confirming the hardware brand or thread separately.
No. The blunt point and machine thread are designed for pre-tapped holes or for through-hole installations tightened with a nut on the back side. To mount hardware to wood panels, drill a clearance hole first and use a nut or threaded insert behind the panel.
Use the 1-5/8 inch length when the door or drawer front is thicker than standard 3/4-inch stock, when hardware mounts through a double-layer panel, or when applied molding adds material depth between the hardware and the panel face. The screw needs enough thread exposed past the back face to fully engage the hardware thread.
The combination recess accepts either a #2 Phillips bit or a flat-blade bit. A #2 Phillips is the faster choice for powered installation; a flat-blade works for hand adjustment or when a Phillips driver is not available.
Zinc-plated screws are a standard choice for interior cabinet hardware installation. The screw shank is not visible once hardware is mounted, so the zinc finish does not need to match the decorative finish on the knob or pull.
Stocking the 1-5/8 inch length alongside your standard hardware screws means thick-door and double-panel jobs get finished on the first trip, without hunting for the right fastener mid-install.
