About this DIN 439 nut

This is a nut made to DIN 439, in 304 Stainless Steel, at strength class A2-035, supplied plain, with an M2 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 439 is the same part as ISO ISO 4035, GB/T GB/T 6172.1, GOST GOST 5916-70. Check the head geometry, the key size and the tolerances before substituting one for another — those do differ between systems.

304 (EN 1.4301, A2) ist die universelle austenitische Edelstahlsorte: gut beständig gegen Süßwasser, Lebensmittelsäuren und atmosphärische Korrosion, im geglühten Zustand unmagnetisch. Sie ist die Standardwahl für Befestigungen im Innenbereich und im allgemeinen Außenbereich bei geringer Chloridbelastung.
