This Würth #8 x 1-1/2 inch truss head machine screw is built for attaching knobs, pulls, and decorative hardware to cabinet doors and drawer fronts. The 8-32 thread is the North American standard for cabinet hardware, so it fits virtually every knob and pull on the market. The 1-1/2 inch length suits thicker drawer fronts, overlay doors, and installations where the hardware mounting post extends deeper into the substrate.
Most cabinet hardware screws run 1 inch or shorter, but some installations call for more thread engagement. The 1-1/2 inch length is well suited to thicker-than-standard drawer fronts, doors with applied molding behind the hardware, or any installation where the knob or pull has a longer shank that requires additional length to reach the tapped hole fully. It also gives a little extra reach when a small spacer or backing plate sits between the door and the hardware base. If you are unsure about length, measure from the back face of the hardware base to the far side of the door or drawer front and choose the screw that fills that distance snugly.
The truss head sits low and spans a wide diameter, which keeps the bearing surface in contact with the back plate of the hardware rather than digging in. That matters when the back plate has a large clearance hole or when the hardware material is softer and prone to dimpling under a narrower head. The combination drive in this screw accepts both a #2 Phillips bit and a flat-blade driver. In a production setting, most installers reach for the Phillips; in a service call or retrofit where bit selection is limited, the slotted option covers the gap. Neither drive requires special tooling beyond what most shops and installers already carry.
This screw is the right choice for any interior cabinet or furniture hardware installation that calls for an 8-32 machine screw. Kitchen and bath cabinet hardware, bedroom and office furniture pulls, media cabinet handles, and built-in millwork knobs are all typical fits. The zinc finish holds up well in dry, climate-controlled interiors. For outdoor furniture or high-humidity environments like pool houses or unconditioned garages, a stainless or coated screw would be a better match.
If your hardware is threaded for 8-32, yes. That is the dominant thread standard for North American cabinet hardware, so most knobs and pulls from any manufacturer are tapped to accept it.
The 1-1/2 inch length suits installations where the hardware shank is long, the door or drawer front is thicker than standard, or a spacer sits between the hardware base and the door face. For typical 3/4-inch doors with standard hardware, a shorter screw often works. When in doubt, measure the required engagement depth before ordering.
It accepts a #2 Phillips bit or a standard flat-blade driver. Both work in the same recess, so there is no need to switch bits if your driver is already loaded with one of those styles.
No. This is a machine screw with a blunt point and machine threads. It requires a pre-tapped hole or a threaded hardware base to install. It will not self-start or thread into wood on its own.
The zinc finish is rated for dry indoor use. For exterior or high-humidity applications, choose a stainless steel machine screw with the same 8-32 thread.
When the length, thread, and head geometry match the job, hardware goes on fast and stays put. This 1-1/2 inch 8-32 truss head screw covers the installations where a standard short screw falls just short, without overreaching into territory that needs a specialty fastener.
