Key specifications

Choosing the right option

Choose the thread form first: the nut must match the bolt in thread form, diameter and pitch. Length is measured from under the head to the end of the bolt. For the bolt on its own: see Hobson Metric Hex Bolt, Class 8.8, Plain, M6 to M36 x 16 to 300mm.

Plain (uncoated) steel has no corrosion protection beyond a light oil film, and it rusts quickly once moisture reaches it. Keep plain parts for dry indoor use, machinery and assemblies that get painted, oiled or enclosed. Outdoors or in damp areas, a hot dip galvanised or 316 stainless alternative is the better choice.

Class 8.8 is a high tensile, medium-carbon steel class, with the minimum tensile strength shown against each size. It suits machinery, structural-style frames and general engineering work. For load-critical, structural or lifting joints, confirm the fastener against the engineer's specification. Fasteners are not lifting rated unless marked.
