What it is
The Fischer MU-SL R lock nut is a self-locking stainless steel nut with an M12 thread, made in compliance with UNI 8835 and DIN 7967 standards to ensure secure locking against loosening caused by vibration. The pack contains 100 pieces, suitable for repetitive work and series supply.
A nut is the female threaded fastener that, screwed onto a screw, bolt or threaded rod, completes the fixing; the category also includes lock nuts, self-locking nuts and coupling nuts.
What it is for
Used for anchoring shelves, brackets and structures to walls, for chemical anchoring, where the load or edge distance rules out a mechanical anchor and for structural fixings, where the fixing is load-bearing and must be calculated.
How to use it
Choose a nut with the same diameter, pitch and material as the screw or rod, zinc-plated with zinc-plated and stainless with stainless. Start the first few threads by hand to avoid damaging them, then tighten with a spanner or socket of the correct size, fitting a washer where needed. Where there is vibration, use a self-locking nut or a lock nut.
