Bremick Hex Head Screw 12g x 20mm Self Driller

The Bremick 12g x 20mm hex head self-drilling screw is a metal fastener without a sealing washer, supplied in a box of 500. The hex head drives with a standard nutsetter, the self-drilling point cuts its own hole in light steel, and the B8 coating gives a hard, corrosion-resistant finish. Because there is no sealing washer, it is the right pick where a plain metal to metal fixing is needed rather than a weatherproof seal.

Frequently Asked Questions

Why would I choose a screw without a seal?

A plain self-drilling screw suits metal to metal fixing where a watertight washer is not needed, such as brackets, clips and steel connections. Where the fixing will be exposed to weather, choose the version with an EPDM sealing washer.

What steel thickness can it drill?

The self-drilling point handles light gauge steel, the thickness you typically fix in brackets, straps and steel framing. For thicker steel, step up to a screw with a heavier drill point or pre-drill the hole.

What drive does it need?

The hex head takes a 5/16 inch (M8) hex nutsetter, the standard drive on roofing and metal fasteners. It gives a positive grip so the screw drives without cam-out.

Is B8 coating good for exterior work?

B8 is a hard, abrasion and scratch resistant alloy, significantly more durable than plain zinc or galvanised finishes. It holds up well outdoors, though for severe coastal exposure check the application against the coating specification.
