Assembly Screw — Funnel Head Countersunk | Pack of 1000

A self-countersinking assembly screw engineered for structural carcase construction in board materials.

Manufactured to a 4mm diameter with a zinc coating, this funnel head screw eliminates the need for pre-countersinking — the head geometry draws flush into the material under torque. The hi/lo thread profile delivers a high-torque, vibration-resistant fix suited to plywood, MDF, and chipboard. Precision manufactured in Taiwan to consistent dimensional tolerances.
