The nylon grips the bolt thread and resists vibration that would loosen a plain nut over time. Simfix stocks nyloc nuts to DIN 985 and the taller DIN 982 in A2 (304) and A4 (316), from M2 to M36, plus flange and domed versions.\u003c\/p\u003e\u003ch3\u003eWhat is a dome nut used for?\u003c\/h3\u003e\u003cp\u003eA dome nut, made to DIN 1587, has a rounded cap that fully covers the end of the bolt thread. It gives a clean, snag-free finish on exposed threads and protects the thread tip. Simfix stocks dome nuts in A2 (304) from M3 to M30 and A4 (316) from M3 to M36, plus domed nyloc nuts (DIN 986) in A2.\u003c\/p\u003e\u003ch3\u003eWhat size nut fits an M8 bolt?\u003c\/h3\u003e\u003cp\u003eAn M8 bolt takes an M8 nut; the number is the nominal thread diameter in millimetres, which matches across bolts, set screws and nuts of the same size. Standard metric nuts have a coarse thread, so check the pitch if your bolt has a fine thread. Simfix stocks M8 full, thin, nyloc, dome, flange, wing and castle nuts in both A2 (304) and A4 (316).\u003c\/p\u003e\u003ch3\u003eShould I use A2 or A4 nuts?\u003c\/h3\u003e\u003cp\u003eUse A2 (304) nuts for everyday indoor and general outdoor use. Use A4 (316) nuts near the coast, around pools or anywhere salt or chlorine is present, since A4 contains molybdenum, which resists chloride pitting that A2 does not. Match the nut grade to the bolt.\u003c\/p\u003e\u003cp\u003eSizes, grades and pack quantities vary by product type.
