For rust prevention measures in heavy salt damage areas.
Introducing a highly corrosion-resistant.
D-Lock Bolt with a unique top coat added to hot-dip zinc-tin alloy plating.
Highly corrosion resistant D-Lock with unique top coating added to hot-dip zinc-tin alloy plating is now available.
We independently performed a 5,000-hour salt spray test and a combined cycle test (150 cycles), assuming the use in a salt-damaged area, and verified the performance.
Please use it for rust prevention measures in salt-damaged areas.
