Bought this allen locking hitch pin to go along with the allen bike rack. Was suppost to be an anti-wobble locking pin, but did not keep it from wobbleing. The bike rack still moved and moved back and forth and mangled the latch for our pop-up camper and was unable to get the tongue of camper off ball on truck. Only made it out of my driveway for that to happen. Nightmare...Bike rack garbage along with locking hitch pin.Returned all products. And then $400.00 later to get pop-up camper fixed since could not be towed, had to have a service call come to us.
