Description
Hex Nut M3, ISO 4032, Stainless Steel A2 — BOLTON SKU 63717.
About the Hex Nut M3 ISO 4032 Stainless
ISO 4032 specifies style 1 hexagon nuts in product grades A and B, and this nut hex m3 iso4032 ss item is the M3 size within that standard. The thread is M3 with the coarse 0.5 mm pitch. Published ISO 4032 dimensions for M3 give a width across flats of 5.5 mm, a width across corners of at least 6.01 mm and a nut height of up to 2.4 mm, so it is driven with a standard 5.5 mm spanner or socket. The material is A2 austenitic stainless steel, the chromium-nickel group covered by ISO 3506-2 for stainless steel nuts. A2 resists atmospheric and mild chemical corrosion without plating, so there is no coating to wear through at the bearing face during assembly and re-assembly. Property class marking and any material certification are confirmed at quotation rather than assumed on this page.

Typical applications
M3 hexagon nuts are used to secure M3 machine screws and studs in electronic enclosures, bracketry, panel assemblies and light structural fixings. The A2 stainless material suits indoor, sheltered and general outdoor assemblies where a zinc-plated carbon steel nut would corrode over time. At only 5.5 mm across flats the nut works in confined spaces such as standoff stacks, cable-gland plates and instrument chassis.
