FAQ
Q1: Will 304 SS really never rust?
A1: 304 resists most salt-air; choose 316 for continuous immersion—polish yearly to keep the shine.
Q2: What safe working load (SWL)?
A2: From 40 kgf (4 mm) to 450 kgf (14 mm); divide total load by number of hooks—safety factor 4:1.
Q3: Can I use the 4 mm for a key-ring?
A3: Yes—9 mm gate clears standard split-rings; 8 g weight is pocket-invisible.
Q4: Will the gate unlock under vibration?
A4: No—spring-lock mechanism stays closed; tested 24 h vibration 50–500 Hz, zero release.
Q5: Are spare 316 versions available?
A5: Yes—316 upgrade on request, MOQ 500 pcs, 20 % price adder.
Q6: Do you offer test certificates?
A6: Mill certificate for 304/316 SS, salt-spray report, and proof-load certificate supplied free on request.
