3 Inch Heavy Duty Stem Casters Swivel Wheels with Brake - 3/8" -16 x 1-1/2" (Stem Diameter 3/8", Stem Length 1-1/2"),Set of 4 with Locking Threaded Stem Caster Wheels - Load 600lbs

Solid casters that thread into metal shelving unit designed for wheels. These are well built and roll smoothly and easily. Brakes are secure and keep shelves secure. They look great too! I would buy again.

This is the cheapest place to find Castor wheels that can withhold weight on Amazon or anywhere else especially if buying them both. Thread is longer than most so it's more secure used for silver metal shelving very easy to install. Definitely recommend to anybody that wants to make something easily movable

Great casters!!..Perfect fit to our steel tool cabinet..Very good quality!!..good ease of movement & rollabillity,easy installment,Greatvalue for the money,Five Star Seller*****

Seem as listed in ad showed up in good condition. Roll easy and locks work

Work better than the stock casters on my shop stool, a little higher and roll better on rougher surfaces.

Why did you pick this product vs others?:After looking at several hardware stores and making many purchases I finally got the perfect size caster for my dolly cart. It also included the bolt and tool to tight en which others didn’t. Very pleased

Measure carefully and you can't go wrong. The wheels fit perfectly but measuring my BBQ Smokers down tube took skill. To the millimeter. Original manufacturer doesn't sell to the public. They said to kiss off! Luckily this company gave accurate measurements so ordering though time consuming, ended very well for me. Better than new wheels.

These are excellent. While it is a smaller wheel - they work perfectly with the "wire shelving racks"
