The Quickscrews M4 x 30 mm truss head machine screw is a fine-thread fastener for attaching knobs, pulls, and decorative hardware to cabinet doors and drawer fronts. The 30 mm length suits most standard door and drawer-front thicknesses where a shorter screw would fall short of full engagement and a longer one would protrude.
Cabinet hardware screws need to pass through the door or drawer front and thread fully into the hardware post. At 30 mm, this screw clears typical 3/4-inch (19 mm) door stock with enough thread engagement remaining for a secure, rattle-free connection. It is the right call for standard overlay and inset door fronts in frameless and face-frame cabinetry, and for drawer fronts in the same thickness range. Installers fitting hardware on thicker custom fronts or stacked material should confirm the combined thickness before selecting a length from this family.
The truss head is wider and lower in profile than a standard pan head, which spreads clamping load across a larger footprint at the hardware base. That broad bearing surface keeps the hardware seated flat and reduces the chance of the head pulling into or dishing soft base materials over time. Fine thread is the correct choice for machine-threaded hardware posts: it produces more thread contact per inch of engagement, which holds the hardware tighter and resists backing out as the cabinet is used daily. The zinc finish handles the climate-controlled conditions of a finished kitchen or bath without issue.
Cabinet installers stocking a hardware kit for a kitchen or bath renovation will find 100 pieces a practical quantity for a standard job. Designers and homeowners sourcing replacement screws for existing hardware can match this M4 fine-thread specification against most European-made and many North American decorative hardware lines. Cabinet shops running production will appreciate having a reliable, consistent-length screw in a combo-drive format that works with either a #2 Phillips or flat-blade driver without a bit change.
M4 is a common metric thread for European-made hardware and is widely used in imported decorative cabinet hardware. North American hardware more often uses the 8-32 thread standard. Check the threading on your specific hardware before ordering to confirm compatibility.
No. The truss head is a non-countersunk profile designed to bear flat against the surface. It seats against the hardware base or the back face of the door without any countersink preparation.
A #2 Phillips bit drives this screw. The combination recess also accepts a flat-blade driver, so either tool works without any adapters.
The zinc finish is rated for dry, indoor use. It is not the right choice for exterior hardware, bathroom hardware exposed to direct water, or any application with prolonged moisture contact.
Length selection depends on the combined thickness of the material the screw passes through. The 30 mm suits standard 3/4-inch door and drawer fronts. The longer options in this family are sized for thicker fronts or stacked material where more thread engagement is needed.
Get the screw length correct and the hardware mounts flat, stays tight, and looks finished from day one. The M4 x 30 mm is the starting point for most standard cabinet door and drawer-front installations.
