Value Collection A210012 Hex Nut M3x0.50 Ss Din 439B 50pk

Product Description

The VALUE COLLECTION A210012 is an M3 x 0.50 hex nut manufactured from 18-8 austenitic stainless steel, conforming to DIN 439B standards. This thin hex nut features a right-hand thread pattern and an uncoated finish, making it well suited for general fastening applications where corrosion resistance is a priority. At 5.5 mm across the flats and 1.8 mm in height, it fits standard M3 threaded fasteners. Machinists, maintenance technicians, and assembly professionals use this nut in light-duty clamping, jam-nut, and lock-nut configurations across a wide range of mechanical assemblies.

This nut is commonly used in light industrial, commercial, and general maintenance settings where metric fasteners are required. Its stainless steel construction resists rust and mild chemical exposure, making it appropriate for indoor and moderately exposed outdoor environments. The DIN 439B profile designates it as a thin or half-height hex nut, often selected as a jam nut to lock a standard hex nut in place or in applications with limited vertical clearance. This listing includes a package quantity of 50 nuts.

Compatibility

Designed for use with M3 x 0.50 metric threaded bolts, screws, and studs in assemblies requiring a DIN 439B thin hex nut profile.

Installation Notes

Installation is performed by hand or with a standard 5.5 mm open-end or box wrench. When used as a jam nut, tighten the primary nut to the required position first, then torque the jam nut against it while holding the primary nut stationary. Do not exceed the fastener or mating component load rating. Stainless steel fasteners can be prone to galling — apply an appropriate anti-seize compound when assembling in high-friction or high-torque applications.
