Frequently Asked Questions

What's the difference between hex head and cup head bolts?

Hex head bolts have a six-sided head that can be gripped and tightened with a spanner or socket, giving more torque than a cup head, which is better suited where the domed head needs to sit flush and smooth.

M10, M12, or M16 — which diameter do I need?

Diameter should match your structural connection requirements — larger diameters carry more load; check with your builder or engineer for your specific application.

What length bolt should I choose?

Bolt length should be long enough to pass fully through your timber section plus the nut and washer — measure your timber thickness before ordering.

Are these bolts trade quality?

Yes, our hex head bolts are hot dip galvanised, high-strength, and trade-quality, suited to decking, fencing, and general construction projects.
