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 a bolt and nut set: see Hobson Metric Hex Bolt and Nut, Class 8.8, Plain, M6 to M36 x 16 to 300mm.

Plain steel carries no protective coating apart from a light oil film, which is why it rusts quickly if it gets wet. That makes it a good fit for dry indoor work, machinery, and assemblies that are painted, oiled or enclosed after fitting. For anything outdoors or damp, choose a hot dip galvanised or 316 stainless option instead.

Property class 8.8 is high tensile, medium-carbon steel. It is the common step up from class 4.6 for machinery, frames and equipment, and the minimum tensile strength is shown against each size. For load-critical, structural or lifting joints, confirm the fastener against the engineer's specification. Fasteners are not lifting rated unless marked.
