This Würth M4 x 25mm truss head machine screw is built for attaching knobs, pulls, and decorative hardware to cabinet doors and drawer fronts where the fastener needs to span a modest material thickness and still engage the hardware post fully. The Phillips/slotted combination drive and zinc finish make it a practical stock item for cabinet shops and installers working through varied hardware specifications.
At 25mm, this screw bridges a gap that shorter hardware screws cannot. Standard cabinet doors and drawer fronts often run 3/4 inch (19mm) thick, and some installations add a second laminated layer, a decorative insert, or a thicker slab-style front. A 25mm screw passes through that material and into a standard knob or pull post with enough thread engagement to hold securely without bottoming out inside a short hardware barrel. It is also the right reach for pulls mounted on doors where the screw has to clear a face frame or an overlay edge before it enters the hardware. Shops that install a range of hardware styles will find the 25mm length handles the middle tier of door and drawer thicknesses that a standard 1-inch screw undershoots and a longer screw overshoots.
The truss head sits flat against the back face of the door or drawer front, spreading the load over a wider footprint than a pan head would. That matters when driving into finished wood or a laminated surface where a smaller head could pull through or leave a visible impression. The M4 fine thread is the standard metric pitch for cabinet hardware in European-specification knobs and pulls, so the screw drops into existing hardware without any thread-matching uncertainty. Zinc plating keeps the screw corrosion-resistant in the controlled indoor environments where cabinet hardware lives.
Designers and cabinet shops specifying European-standard hardware will find this screw fits the metric hardware ecosystem without a conversion search. Installers working through a kitchen or bath renovation who carry a mixed bag of hardware can keep a box of these on hand to cover the moderately thick door and drawer fronts that come up on most residential jobs. The combination Phillips/slotted drive means the screw is usable even when a dedicated #2 bit is buried in a tool bag, cutting down on the small delays that stack up over a full installation day.
This screw uses the M4 metric thread, which is common on European-specification cabinet knobs, pulls, and decorative hardware. It threads into any hardware post tapped to the M4 standard.
The truss head has a wider, flatter bearing surface than a pan head, which distributes clamping force over more of the door or drawer back face. This helps prevent the head from pulling through or denting finished surfaces during installation.
Yes. The combination recess accepts a #2 Phillips bit or a flat-blade bit. Either will seat and drive the screw without needing a specialty tool.
The zinc finish is suited for dry indoor environments. For installations in high-humidity areas like outdoor kitchens or marine cabinetry, a screw with a heavier corrosion-resistant coating would be the better choice.
Yes. Machine screws thread into pre-tapped holes, and a blunt point aligns cleanly with the existing threads rather than forcing a new path. It reduces the chance of cross-threading, which is especially useful when installing delicate hardware with softer threaded inserts.
When the door thickness calls for a 25mm reach and the hardware runs M4 metric, this Würth truss head machine screw removes the guesswork and keeps the installation moving.
