The BMN-M25 is the black variant of ABB’s MN-type polyamide lock nuts and mates with matching M25 x 1.5 male threads to secure fittings in conduit and protection applications. It has a 32 mm wrench size and a height of 6.0 mm, creating a compact locking element for space-constrained installations. The nut is made from polyamide 6. In ABB catalogs, BMN-M25 is listed alongside the gray GMN-M25 as part of the MN family of hexagonal lock nuts, confirming its threading and color. Use this part to securely lock M25-threaded connections within PMA fittings and conduit systems.
