You're mid-job, the nut's about to back out, and you've got a handful of mixed-up fasteners from the last batch. Stop. These are M5 nyloc nuts in 316 stainless steel, sealed pack of eight. What the pack says is what's in it — no bin-mixing, no 'is this 304 or 316?' guesswork. The nylon insert grips your bolt so vibration doesn't undo six hours of work. Grab the pack, get back to the job
