3/8" threaded stem casters for light-duty carts, racks, fixtures, and mobile equipment. Commonly used as replacements for wire shelving, utility carts, and institutional equipment where a compact threaded mounting interface is required.
Threaded stems install into tapped plates, inserts, or compatible equipment legs and are typically secured with a nut for positive retention. Stem length and thread engagement must be verified to ensure adequate holding strength.
If you are adding threaded stems to wood legs or panels, use a properly sized tee nut or insert to provide metal threads and prevent pull-out. For 3/8" tee nuts: Shop 3/8" tee nuts.
