3/8" Threaded Stem Casters

Diameter: 2, 2-1/2, 3 inTread: 13/16, 7/8, 1 inCapacity: up to 350 lbStem: threaded
3/8-16 threaded stem casters fit smaller tapped holes on light carts, display fixtures, and institutional equipment. 2 to 3 inch wheels with narrow 13/16 to 1 inch treads keep overall height low while carrying about 80 to 350 lb. Hard rubber, TPR, and polyurethane compounds cover finished floors and light shop use. Verify thread pitch and stem length against the existing nut plate before bulk ordering.

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.

Selection and compatibility guidance

How threaded stem mounting works

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.

Installing into wood (tee nut option)

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.

Wheel material options
  • TPR / TPE: Quiet rolling and floor protection; better over small debris and cords
  • Polyurethane: Higher load capacity; improved durability and reduced flat-spotting
  • Rubber: Cushioned ride and good traction; verify capacity and rolling resistance
Typical construction features (model dependent)
  • Ball-bearing swivel raceway for smooth rotation
  • Zinc-plated finish for corrosion resistance
  • Axle hardware varies by model (rivet, nut/bolt, or staked)
  • NSF-certified models available where required
Common applications
  • Wire shelving and utility racks
  • Institutional and food service carts
  • Retail displays and light fixtures
  • Office and light-duty equipment stands
What to confirm before ordering
  • Thread size (commonly 3/8"-16, but verify)
  • Stem length and required thread engagement
  • Overall height constraints
  • Wheel material for floor type and environment
  • Brake requirement (if equipment must stay fixed)
