Micro Lock Nut DIN 439B

SKU: MF08 Categories: ,

Micro Lock Nuts, created to DIN standard 439B are standard nuts with a reduced height in comparison to a Hexagon full nut.

Otherwise known as Half Nuts, these fasteners are commonly used with any male fastener with the same thread diameter and pitch. Commonly used to mate a stack or single part together.

They can be installed or removed using standard spanners or socket tools.

It is important to consider that the tensile strength of the nut should not be more than that of the bolt or mating component as this can cause thread ‘stripping’.

Available from stock in steel grade 8, A2 and A4 stainless steel, brass and other materials such as aluminium or titanium.

Standard sizes from M2 to M3 with larger diameters also available.
