    Do metric nuts loosen vibration?
    Made with fine-pitch threads, vibration is less likely to loosen these metric nuts than those with coarse-pitch threads since the threads sit closer together. Also called jam nuts, they are roughly half the height of standard hex nuts, so they’re good for applications with low clearance.

    How do you tighten metric nuts?
    To tighten metric nuts, turn them to the left. Once fastened, they resist loosening from counterclockwise motion. These nuts have good chemical resistance and may be mildly magnetic, comparable in strength to Grade 5 steel and as resistant to chemicals and salt water as 316 stainless steel.
