Black Stainless Steel Dome Nuts DIN1587 Blackened Finish Nut Fasteners and Fixings (Pack of 10) (M3 / 3mm)

A2 304 STAINLESS STEEL WITH BLACKENED FINISH – CORROSION RESISTANT & VISUALLY ELEGANT Manufactured from A2 304 stainless steel for genuine rust and corrosion resistance, then treated to a deep matt black finish. Unlike black-coated mild steel dome nuts that rust within months once the coating is scratched, these retain full corrosion resistance for life — making them ideal for visible decorative fixings, classic vehicle restoration, and any project where black hardware must genuinely last. DIN 1587 ACORN DOME DESIGN – DECORATIVE FINISH & THREAD PROTECTION Precision-manufactured to the DIN 1587 standard, these closed-end "acorn" dome nuts feature a smooth rounded dome that fully encloses the bolt thread end. Delivers a clean decorative finish on visible hardware while protecting thread ends from damage, snags, and injury risk — particularly important on handrails, garden furniture, children's equipment, and any installation where finger contact is likely. PACK OF 10 M3 BLACK DOME NUTS – READY FOR DECORATIVE & FUNCTIONAL FIXINGS Each pack contains 10 individual M3 black dome nuts with M3 x 0.5mm metric coarse thread. A practical quantity for decorative bolt finishing on furniture, handrails, railings, gates and garden structures, vehicle bodywork and chassis fixings, motorcycle restoration projects, bed frame assembly, signage and architectural metalwork, and any application requiring a clean black finish over an exposed bolt end. DECORATIVE & SAFETY-FIRST FINISH – COVERS SHARP THREAD ENDS The closed dome design hides the cut end of any bolt or threaded stud — eliminating snag hazards on clothing, skin, or pets, while delivering a professional finished appearance. Particularly valuable in family environments (cot frames, garden swings, playground equipment), exposed handrail terminations, decorative metalwork, and any visible installation where the alternative — a raw cut thread end — would look unfinished or be a snagging risk. The black finish coordinates beautifully with modern black hardware, dark furniture, motorcycle frames, and architectural metalwork. UNIVERSAL M3 THREAD – COMPATIBLE WITH ALL STANDARD M3 BOLTS & STUDDING With a standard M3 x 0.5mm right-hand coarse pitch thread, these dome 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 A2 304 stainless steel hex bolts, button head socket screws, and threaded studding for a complete corrosion-resistant black fastening solution with a clean decorative finish.
