Key specifications

Selecting the right option

Select your Hobson hex nut to match the bolt thread form, diameter and property class. For vibration-prone applications, consider a nyloc (polymer insert) nut. Heavy hex and structural nuts are available for high-load flange and structural connections. Finish options include zinc plated, hot-dip galvanised, stainless and nylon. Call AIMS if you're unsure about pairing for a specific standard or load requirement.
