     TONEJI CO., Ltd announces new innovative coating technology. The all-new Super Coat SST5000 applied on TONEJI's D-LOCK bolts on top of their hot-dip zinc-tin alloy plating is now available. SST5000 cleared a 5,000-hour salt spray test and a combined cyclic test (150 cycles), with minimized white rust and no red rust. This new coating is ideal for rust prevention measures in salt-damaged areas.
