Collection: Self Tapping Screws Undercut Zinc

Undercut Self Tapping Screws Overview

Hardened countersunk self tapping undercut screws (also called hinge screws) from our high performance screw range. These Phillips No2 drive screws are designed to drill and tap their own hole as they are screwed into wood, plastic or thin to medium gauge steel creating their own precisely fitted threads.

The countersunk head on self tapping undercut screws is cut away mid point to give a flat bottom as opposed to a full taper. This allows the screw to sit flush in a thin countersunk metal plate, usually a hinge or bracket. The reduced head thickness allows a flush fit in the component without bottoming out on the substrate. Also available in stainless steel for maximum corrosion protection.
