Pins stay on the hook. Tailgates stay shut.
HardwareMFG builds 9/16″ locknut and 7/16″ hair-cotter latch kits in the Midwest for tailgate latching and ramp retention. Roll-threaded J-hooks with weld-on tubes, spring, and nut. Custom and standard sizes.
Traditional hairpin J-hooks shed pins on rough roads, snag clothing and arms, and jam when the top takes an impact or a boot. Import wire often runs nominal 7/16″ or 1/2″. A production trailer should not ship with that fight built in.
Why it holds
Threaded rod and locknut stay put on rough roads. The tailgate is not supposed to flop open in transit.
The locknut kit drops the sharp cotter that catches sleeves and skin.
Impact or a boot used as a step is less likely to jam the hook so someone has to hammer it loose.
9/16″ wire vs common import 7/16–1/2″. Yellow zinc dichromate. Two un-plated tube diameters (CA-875-2, CA-1125-1.5) for frame and tailgate fit.
Pick the assembly that matches your print. Each kit ships hook, spring, and weld-on tubes together, not a loose J-bolt from a fastener house. Custom and standard sizes.
