Waterproof Snap Buttons
304 & 316 Stainless Steel — Marine, Outdoor, Industrial
Rust-Proof · Saltwater-Tested · Wholesale from Turkey
Snap Fasteners That Survive the Elements
Standard brass or zinc-alloy snap buttons fail quickly in marine, outdoor, or industrial wash environments. Salt corrodes, chlorine pits, repeated humidity dulls finishes within months. Waterproof snap buttons made from 304-grade stainless steel resist all of this — with a typical service life of 10+ years even in continuous outdoor exposure. Ata Buttons supplies marine cover manufacturers, outdoor apparel brands, and technical workwear producers across Europe, USA, and Asia.
- Salt-spray test (ASTM B117): 1,000+ hours without significant corrosion
- Cycle test: 10,000+ open/close cycles in laboratory conditions
- UV exposure: No finish degradation after 5 years equivalent UV
- Industrial wash: Survives 100+ commercial laundry cycles at 90°C

Frequently Asked Questions
Can I use brass snap buttons outdoors?
Yes for short-term and dry climates. Solid brass with lacquer coating works well for outdoor fashion and light marine use (1-3 years). For permanent outdoor exposure, saltwater, or wet-cycle laundry, switch to 304 stainless steel — the lifespan difference is 10x.
Are these compatible with DOT (Common Sense) fasteners?
Yes — we manufacture DOT-compatible stainless steel snap buttons that mate with existing systems on boats and trailers. Specify "DOT-compatible" at order; we provide the matching stud/post sizes.
What is the MOQ for stainless steel snap buttons?
5,000 pcs per style/size for grade 304. Grade 316 has slightly higher MOQ (10,000 pcs) due to specialty raw material sourcing. Free sample kit in 3 days — includes 304 and 316 samples for comparison.
Do you offer painted or PVD finishes on stainless steel?
Yes — black PVD, gunmetal, gold PVD, and powder-coat colors are all available on stainless steel. PVD is preferred for marine/outdoor because it bonds molecularly and won't peel like paint. Painted finishes are an economical option for light-duty outdoor use.
