Frequently Asked Questions
What is a cup head bolt used for?
The domed head sits flush and smooth on the exposed face, commonly used for bolting timber connections like posts, beams, and fencing where a neat, snag-free finish is wanted.
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 suitable for coastal areas?
Hot dip galvanised offers strong general corrosion resistance for most applications; for coastal or marine environments, a stainless steel option may be preferred for longer-term performance.
