About this DIN 985 nut

This is a nut made to DIN 985, in Aluminium Alloy, supplied anodised, with an M8 thread. Every dimension is stated against the standard named above; where a tolerance class matters to your design, ask us and we will confirm it in writing before you order.

A nut is the closing half of a bolted joint. Its property class is chosen to match the bolt it is paired with — a class 8 nut for a grade 8.8 bolt, so the thread strips before the bolt breaks. Used wherever a bolt or stud has to be tightened from the far side, and for locking and positioning duties on machinery and steelwork.

DIN 985 is the same part as ISO ISO 10511, GB/T GB/T 889.1. Check the head geometry, the key size and the tolerances before substituting one for another — those do differ between systems.

Aluminium alloy is roughly one third the weight of steel with excellent corrosion resistance and conductivity. Use it for lightweight assemblies and check for galvanic corrosion against steel or stainless parts.

Sold by the piece, so one is a valid order. Stock lines leave our warehouse within 24–48 hours of cleared payment, and freight is calculated at checkout from the packed weight and the destination.
