MIDWEST FASTENER CORP 36703 Tube Linch Pins 3PK

3/8-inch tube linch pins for farm and trailer use

This three-pack supplies replacement linch pins sized at 3/8-inch diameter for securing wheels, gates or implements on agricultural and light-trailer equipment. The pins are built for repetitive insertion and removal in outdoor conditions. They suit owners who need a small quantity of spares for routine maintenance.

Simple drop-in installation with spring-loaded ring

Each pin inserts through the axle or clevis hole and locks by snapping the attached ring over the shaft end; no tools are required beyond hand pressure. The main failure point is a bent pin body or a weakened ring spring caused by forcing the pin into a misaligned or corroded hole. Inspect the ring tension before every use and discard any pin that does not snap closed positively.

Verify hole diameter and usable length before

Confirm that the mating hole measures 3/8-inch so the pin seats without excessive play or binding. Check that the distance from the hole centre to the shaft end allows the ring to clear and lock fully. Ensure the shaft material is sound enough to hold the pin under side loads typical of trailer or implement connections.
