Chipboard Screw Countersunk with Nibs | 4.2 x 57mm — Zinc | Pack of 1000
A high-thread chipboard screw engineered for reliable fastening in cabinet carcass construction without pre-drilling.
Manufactured in Taiwan to consistent dimensional tolerances, this countersunk screw features a nibs profile beneath the head that seats flush into chipboard and MDF without splitting. The zinc coating provides corrosion resistance suited to dry interior cabinetry environments. Its self-threading design cuts cleanly into particleboard, making it the standard choice for flat-pack and site-assembled cabinet builds.
