Bremick Roofing Screws 6.2mm x 50mm

The Bremick 6.2mm x 50mm roofing screw is the most common length for fastening metal roofing sheets to timber battens and steel purlins. The hex head drives with a 5/16 nutsetter, the timber and steel drill point cuts its own hole, and the B8 coating protects the exposed head from corrosion. It is sold in packs of 100 and 1000, so a small repair and a full roof run are both covered.

What You Need To Complete The Job

For a longer fixing into thick timber use the 6.2mm x 65mm roofing screw, and for a short trim fixing the 6.2mm x 25mm version. Where the battens themselves go down, use roofing batten screws 12g x 40mm. Browse the full Screws range and the Metal Roofing range for the complete system.

Frequently Asked Questions

What steel thickness can it drill?

The drill point handles timber or steel up to 1.6mm thick, which covers the steel purlins and battens used in metal roofing systems. Heavier structural steel needs a heavier drill point screw.

Why is 50mm the standard length?

At 50mm the screw passes through the sheet crest and into the batten or purlin with enough thread engagement to hold under wind load, without being so long that it is awkward in thin timber. That is why it is the everyday roofing sheet fixing.

What pack size is right for a house roof?

A typical house roof uses several hundred sheet fixings, so the 1000 pack is the practical size for a full re-roof. The 100 pack suits a small shed, a repair or topping up a box.

Can these screws be used for polycarbonate sheeting?

Polycarbonate needs a screw with a cutting wing and an oversized sealing washer to allow the sheet to expand and contract, so use a dedicated polycarbonate fixing screw for that job instead. See the Screws range for the polycarbonate options.
