Frequently Asked Questions
What size threaded stem do these casters use? ›
CasterHQ's TPR threaded stem casters use a standard 1/2″-13 UNC thread, the most common stem size in the caster industry. This fits most wire shelving units, food service racks, and industrial equipment.
How do I install a threaded stem caster? ›
Simply screw the threaded stem clockwise into the threaded socket on your equipment leg. Hand-tighten, then snug with a wrench. No drilling, bolts, or top plate required.
Can I use threaded stem casters on wire shelving? ›
Yes. Most commercial wire shelving units use 1/2″ threaded sockets that accept these casters directly. Gray TPR wheels are the best choice for non-marking, quiet rolling.
