Threaded Stem Casters (3/8″ & 1/2″) Up to 350 lbs

Threaded Stem Casters

COMPACT MOUNT • MECHANICAL RETENTION • OEM USE

Threaded stem casters are specified where plate mounting is not practical and a compact, mechanically retained connection is required. These casters thread directly into tapped holes, inserts, or equipment legs and are secured with a nut for positive retention.

Commonly used on carts, fixtures, mobile equipment, and OEM assemblies, threaded stem casters offer secure alignment, serviceability, and optional height adjustment.

Available Threaded Stem Sizes

1/2" Threaded Stem Casters Heavy-duty threaded interface · common OEM standard 3/8" Threaded Stem Casters Compact stem size · light to medium-duty equipment

Typical Configuration Envelope

Threaded stem casters with 3/8 inch and 1/2 inch threaded stems, swivel and brake options, and wheel diameters from 3 to 5 inches.

Common Stem Sizes: 3/8" and 1/2" (thread pitch varies by series)
Wheel Diameters: Typically 3"–5"
Load Capacity: Up to 350 lbs per caster (model dependent)
Mounting: Threaded stem with nut for secure retention
Options: Swivel, brake, and total-lock configurations
Environments: Institutional · industrial · medical · laboratory

Selection tip: Verify stem diameter, thread pitch, usable thread length, and load per caster. Threaded stems provide stronger retention than press-fit stems when alignment and durability matter.

Selection Guidance

When to specify a threaded stem caster

Limited space prevents plate mounting
Equipment legs or frames have threaded inserts
Positive mechanical retention is required
Occasional height adjustment is needed

Threaded stem vs grip ring stem

Threaded stems provide positive mechanical engagement and consistent alignment. Grip ring stems install faster but rely on tube tolerances for holding strength.
