Titanium Steel 316L PVD 18K Gold Lobster Clasp
The 316L PVD 18K gold lobster clasp is a precision jewelry finding for professional jewelers, accessories makers and OEM/ODM clients. Manufactured from marine-grade 316L stainless steel — the same alloy used in surgical instruments — and coated by Physical Vapor Deposition (PVD) with an 18K gold finish, it delivers exceptional corrosion resistance, long-lasting color retention and a mirror-bright look that rivals solid gold findings at a fraction of the cost.
The spring-loaded gate operates with a smooth, positive snap action for secure everyday closure while remaining easy to operate one-handed. Its compact profile and top-mounted jump-ring loop are compatible with box, cable, rolo, rope and snake chains. 316L steel withstands sweat, seawater, perfume and chlorine, making it the preferred choice for waterproof, sports and sensitive-skin jewelry lines.
