Manufactured from high-quality marine-grade 316 stainless steel, the NX SeaPro bolt snaps offer exceptional strength with outstanding resistance to corrosion and rust, even in harsh salt-water environments. The swivelling base allows smooth, effortless operation, reducing line twist and making clipping and unclipping fast and reliable. Large snap sizes are specifically designed for equipment, such as backup lights, long regulator hoses, canister lights, SPGs, and other critical accessories. These large snaps truly excel in cold-water diving, where thick gloves can make fine manipulation difficult. Their generous size and positive action ensure dependable handling when precision and reliability matter most.
