Product Overview
High-Quality Snap Hook Shackle – Stainless-Steel Egg-Shape Spring Hook – Model ZB6205 Series
RICHWITS ZB6205 gives you an “egg” profile that delivers higher strength with less weight—ideal for marine, pet, handbag and hammock hardware.
Precision-investment-cast from 316 marine stainless, then mirror-polished and electropolished for lifetime immunity to salt-spray, chlorine and tropical humidity.
Egg-shaped basket spreads load evenly; spring gate closes with 4 kgf preload yet opens under 12 kgf pull—one-hand friendly, even underwater.
Five sizes (40–100 mm) cover working-load limits from 80 kgf to 500 kgf—perfect for shade sails, pet leads, diving belts, handbag straps or heavy-duty hammock suspension.

FAQ
Q1: Will 316 SS really never rust in seawater?
A1: Correct—2-3 % Mo gives lifetime immunity to chlorides; rinse with fresh water after each voyage to keep the mirror shine.
Q2: What safe working load (SWL) per egg hook?
