Review on Ultimate Strength and Durability: Aobbmok Solid Steel Plated Collars - Unmatched Performance for Serious Lifters by Sean Garrison

Two weeks after purchasing a new hand truck, the thrust washer fell off the axle and was lost. For several months I had to steer carefully to keep the left wheel from slipping off the axle. I finally bought this set of stem clamps and everything is solved. They're easy to install and hopefully a lot more reliable than previous press washers.
