Chipboard Screw Countersunk with Nibs | 4.2 x 40mm — Zinc (1000-Pack)
$37.28
A high-thread chipboard screw engineered for reliable fastening in cabinet carcass construction without pre-drilling.
Zinc-coated for corrosion resistance, this countersunk screw features nibs beneath the head that seat flush into chipboard and MDF, preventing surface tear-out. The self-tapping thread cuts cleanly into particleboard and melamine-faced board, delivering consistent pull-out resistance across repeated assembly cycles. Suited to production cabinetry environments where speed and repeatability matter.
