A nylon insert lock nut (nyloc) resists loosening under vibration: the threads cut into a nylon collar that grips the mating screw. In stainless steel, the catalog carries 18-8 / A2 and 316 / A4 grades, standard NM and thin NTM patterns, and mil-spec MS17830 and MS21083 series, across unified coarse, fine, and metric threads. Every record below carries a live source link, so the price and the spec can be checked against the seller's own page.
