Key specifications

Choosing the finish

A hot dip galvanised finish is a heavy zinc coating made for outdoor and long-term exposure, including structural steelwork, roofing and fencing.

In coastal splash zones and within about 1 km of the sea, 316 stainless is generally the better choice.

A hot dip galvanised nut is tapped oversize after galvanising to allow for the coating, so match it with galvanised bolts. A clean, dry-to-touch lubricant on the nut threads helps when tightening.

What the class means

These are Class 8.

Fasteners are not lifting rated unless marked.

Choosing the right option

Match the nut to the bolt, stud or rod: thread form, diameter and pitch must all agree. Sizes are the nominal thread diameter in millimetres; compare the pitch with your bolt.
