M3 Hex Nuts Black Stainless Steel DIN934 Blackened Finish Nut Fasteners and Fixings (Pack of 10

STAINLESS STEEL CORE WITH BLACKENED FINISH – CORROSION RESISTANT & VISUALLY DISCREET Manufactured from stainless steel for excellent rust and corrosion resistance, then surface-treated to a deep matt black finish. Unlike black-coated mild steel nuts that lose their corrosion protection the moment the coating is scratched at install, these nuts retain their corrosion resistance throughout their service life. Ideal for visible installations on vehicles, motorcycles, classic car restorations, and any project where black hardware needs to genuinely last — not just look good for six months before rusting. DIN 934 STANDARD HEX NUT – RELIABLE METRIC FASTENING Precision-manufactured to the DIN 934 standard, these full-height hexagon nuts deliver consistent, reliable clamping force across a wide range of fastening tasks. The standardised hex profile means they work with all common metric spanners and sockets, while the full thread engagement provides the holding strength expected of a standard finished hex nut — a dependable, no-surprises fastener for trade and DIY use alike. PACK OF 10 M3 BLACK HEX NUTS – READY FOR AUTOMOTIVE, ENGINEERING & DIY USE Each pack contains 10 individual M3 black hex nuts with M3 x 0.5mm metric coarse thread, taking a 5.5mm spanner. A practical quantity for vehicle bodywork and chassis fixings, exhaust system assembly, motorcycle restoration, engine and gearbox mounts, machinery assembly, agricultural equipment, garden machinery repairs, and any DIY or trade project requiring corrosion-resistant black fasteners in a discreet matt finish. BLACKENED FINISH PROTECTS APPEARANCE & BLENDS INTO DARK ASSEMBLIES The blackened surface treatment delivers a clean, low-reflectivity matt black appearance that blends discreetly into dark bodywork, frames, brackets, and finished mechanical assemblies. Because the corrosion resistance comes from the stainless steel itself rather than the surface coating, a minor scuff or scratch during installation will not lead to rust bleeding from the fastener — particularly important on visible bodywork, motorcycle frames, and finished mechanical assemblies. UNIVERSAL M3 THREAD – COMPATIBLE WITH ALL STANDARD M3 BOLTS & STUDDING With a standard M3 x 0.5mm right-hand coarse pitch thread, these hex nuts are universally compatible with all M3 metric bolts, hex bolts, machine screws, threaded studs, and threaded rod across all major brands. Pairs perfectly with stainless steel hex bolts, button head socket screws, and threaded studding for a complete corrosion-resistant black fastening solution.
