Timberfast Winged Self Drilling Screws – Countersunk BZP

Timberfast Winged Self Drilling Screws – Countersunk BZP

Timberfast® light-section self-drilling screws manufactured from case-hardened steel with a zinc plated Cr3 finish, designed for fixing timber to suitable light-gauge steel sections.

Each screw features a self-drilling point with wings that create clearance through the timber before reaching the steel. The wings are designed to break away on contact with the metal, allowing the screw threads to engage.

The countersunk head incorporates ribs to assist with countersinking into suitable timber, helping achieve a flush fixing.
