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.
