What it is
The Fischer FTRC locking nut is a nut with an M12 metric thread, a thickness of 8 mm, a 19 mm tightening spanner size and a recommended installation torque of 20 N·m, designed to ensure stable fixing within support systems. It is supplied in packs of 50 pieces.
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 mechanical fixing of structures and components to walls, ceilings and floors, for erecting steelwork and structural carpentry and for supporting pipework and ductwork.
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.
