All measurements indicate the wheel diameter by the tread width.
The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.
W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.
Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.
Complete swivel casters
Complete 5″ swivel shopping cart casters on the universal 1/2″-13 threaded stem. Genuine P&H forks with USA-made P&H wheels, plus lock-nut kits and front and rear sets. One caster or a full fleet, shipped from Mansfield, Texas.
These are complete swivel casters on 1/2″-13 threaded stems. Measure stem length (7/8″, 1″, or 1-1/8″) from the top of the swivel to the end of the thread. Fork still good? Shop wheels only.













Not sure which stem length your cart takes? Call 844-439-4335 or send a photo of the old caster with a tape on the stem and we will match it.
The universal North American standard is a 1/2″-13 threaded stem. Stem length is the variable: 7/8″ is the most common on carts built since 2000, with 1″ and 1-1/8″ on some frames. Measure from the top of the swivel plate to the end of the thread. The thread size, not the length, is what makes it universal.
Standard grocery and retail carts run swivel casters at the front and rigid forks at the rear. The threaded-stem casters on this page are the front swivel positions. Rear rigid positions normally take a wheel-only replacement, which is on the wheels page.
Yes on carts built since 2000. Those brands share the 1/2″-13 stem, 5″ wheel, and 5/16″ bore, so a 5″ swivel caster with the correct stem length drops in. Imported plastic carts, European carts such as Wanzl, and pre-2000 frames vary, so measure the old stem first or send us a photo.
The P&H casters here are the genuine parts the cart manufacturers install, with the patented USA-made P&H wheel on an imported zinc-plated swivel fork. Tiles marked Industry Standard are the most commonly specified replacement families for U.S. retail fleets. Tiles without the OEM chip are universal-fit alternatives that match the same 1/2″-13 stem and 5″ wheel.
The kit listings include the complete swivel caster plus the lock nut for the threaded stem, so one SKU covers the position. Single casters and 2-packs marked "lock nut included" on the tile also ship with the nut. Check the tile meta line before ordering.

Cart casters thread into a socket in the frame. All of these use 1/2-13 thread; measure the thread length on the old caster from the top of the swivel race, then pick 7/8 in or 1 in to match. A stem that is too long bottoms out before the swivel seats.
