The Quickscrews M4 x 45mm truss head machine screw is built for attaching cabinet knobs, pulls, and decorative hardware through thick drawer fronts, stacked panels, or any application where a shorter machine screw falls short. The combination Phillips/slotted drive and wide truss head give installers flexibility on the driver and a broad bearing surface at the face.
Most cabinet hardware installs call for a 25mm or 32mm machine screw, but some jobs demand more reach. A thick slab drawer front, a layered panel with backing, or a pull mounted through decorative overlay material can easily push the required screw length past what a 30mm or 35mm screw can handle. The 45mm length bridges that gap, threading fully into the hardware receiver while the truss head clamps the assembly firmly at the face. It is also useful when a designer specifies extra thread engagement for heavier bar handles or cup pulls that see repeated load cycles.
The truss head on this screw sits lower than a standard pan head while spreading clamping force over a wider footprint. That combination keeps the back of the panel clean and reduces the chance of the head telegraphing through thin face material. The M4 fine thread is the correct specification for the threaded posts built into most North American and European decorative hardware, and the blunt point seats squarely in those receivers without any tendency to wander. Zinc plating provides the corrosion resistance appropriate for dry interior environments — kitchen and bath cabinetry, furniture, and built-ins where the screw stays out of sight behind the door or drawer front.
Cabinet installers hanging hardware on thick shaker-style or slab drawer fronts keep a box of 45mm machine screws on the cart for exactly the moments when a shorter screw bottoms out before the hardware seats. Designers specifying oversized pulls or long bar handles on layered panel constructions will often call out the longer length in their hardware spec to ensure full thread engagement. Shops that assemble custom furniture with recessed hardware pockets or decorative overlay fronts find the 45mm length handles the geometry that shorter screws cannot. Packed 100 to a box, this SKU supplies enough for a typical kitchen run or a multi-piece furniture project without carrying excess inventory.
When mounting hardware through a thick drawer front, a layered panel, or a decorative overlay, a shorter screw may not reach the threaded receiver inside the hardware. The 45mm length provides the extra reach to seat fully and clamp the hardware securely.
No. The truss head bears flat against the surface — it is not a countersunk head and does not require a countersink hole. It sits on top of the panel or hardware base and clamps from above.
Yes. The combination recess accepts a #2 Phillips driver or a flat-blade driver in the same head, so either bit works for installation.
M4 is a common metric thread used in European-style hardware and some North American decorative hardware lines. Always confirm the thread specification in the hardware's installation instructions before ordering, since 8-32 UNC is the other widely used cabinet hardware thread and the two are not interchangeable.
The zinc finish is rated for dry interior environments. For outdoor or high-humidity installations, a stainless steel or coated screw is the better choice.
When the job calls for hardware mounting through material that shorter screws cannot bridge, the Quickscrews M4 x 45mm truss head machine screw delivers the length, thread engagement, and driver flexibility to keep the install moving cleanly.
