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 80 kgf (3.5 mm) to 1 400 kgf (14 mm); divide total load by number of links—safety factor 4:1.

Q3: Can I use the 4 mm for a key-ring?
A3: Yes—5 mm gate clears standard split-rings; 13 g weight is pocket-invisible.

Q4: Will the gate unscrew under vibration?
A4: No—CNC threads stay tight; hand-torque plus ¼ turn with 19 mm spanner for max load.

Q5: Are spare 316 versions available?
A5: Yes—316 material on request, MOQ 500 pcs, 15 % price adder.

Q6: Do you offer test certificates?
