MySit 4pcs Stem Casters M8x25 with Brake Lock | 2 Inch Heavy Duty PU Rubber Swivel Castor Wheel Shopping Trolley - Threaded Stem Bolt with Nuts (CasterBrake50_8x25N)

These casters have a metric 8mm-1.25 threaded post. For my application I had to cut the posts shorter and chase the threads with a 5/16”-18 die to recut the posts to the right size since what I was installing them on had bosses with 5/16"-18 tapped holes. This modification may not be suitable for your application depending on what you are doing since it does damage the threads. These are good quality casters for the price.UPDATE: Customer service by the company is excellent. There was an issue with the product description which was inaccurate. When this was brought to their attention they promptly corrected the product title.

Decent quality, but be aware installation can be a bit tricky. The threaded shank (8mm-1.25) has a 14mm hex at the base, but it sits in a recess. To install these casters, you will need a THIN wrench (approximately 1/8" maximum thickness) to be able to thread them all the way in. You will need a 14mm (9/16" also works) tappet wrench or similar for installation. A regular open end wrench is too thick to work.Also, be aware the pivot bearing is NOT sealed, so this could eventually cause problems in a shop environment.

YGWYPF - You get what you pay for. So make adjustments. These are nice casters but clearly not intended to be carrying a lot of weight. For my 45 lb Central Pneumatic 1.5 HP 6 Gallon 150psi compressor, these casters represent Nirvana compared to the rubber-bolted feet that came on the compressor.But there's a hitch. The stationary nut welded in place to the each caster's bolt assembly...in it's original state...left little working room for all but the narrowest of wrenches when tightening the caster assembly to the base of (e.g.) a 6 gallon compressor.I've read where others experienced the same problem. I found a simple solution. To assure you have more room/leverage to tighten each caster to your compressor, see if you don't have 4 nuts exactly the same size as the one welded to the caster bolt. I did. I then simply screwed the new nut onto the bolt all the way to the bottom, as a spacer, aligning the two nuts as closely as possible to give you plenty of room to get them very tight against the housing. You can get a very snug fit, especially if you have a nut and lock washer combo threaded onto the caster bolt from the inside. A 14mm open-end wrench seemed the best match for these dual nuts to tighten the whole thing down. But it worked perfectly.And the casters are terrific so far! The casters make the compressor very easy to move and position. And while locking all 4 wheels won't feel as stable as the heavy rubber feet of the original, they work for in-place positioning.Hope all this helps.

If you’re looking for a great alternative to castors “designed” for Marshall or Blackstar cabs these are it.They fit perfectly.In the case of the Marshall 1936 cab without feet they can be installed without the use of the included nuts. Just as simple as screwing them in. I used the nuts anyway.With the Blackstar the nut was necessary as a spacer so that the brake leaver would clear the rubber feet and spin freely.With both I found it easiest to install with the brake engaged allowing me to hand tighten them. There’s no need to tighten them more than hand tight, especially in the case of the Blackstar who’s castor receiver is plastic.Get these and never worry your amp will dance away if you leave them on. That’s why they have brakes!

Described as advertised, these are rolling good even on my rug(very low pile loop rug) I used these stem casters to replace feet that were on an storage ottoman. Now when I need to move the ottoman with pounds of items in it I don't have to lift it, just roll it aside. For those of you who don't know what size bolt you have to replace screw in furniture feet with this stem caster you should make life easier buy purchasing a bolt/nut measure.

I purchased these locking casters to insert on the legs of this inexpensive table I found at Habitat for Humanity. I wanted to increase the height of the table as well as make it mobile. These wheels allowed me to do both. I plan on using it for a table for two as well as extra counter space in a tiny house. I’m very happy with the MySit 2 Casters purchase.

These casters have been amazing. I bought these to replace the crappy plastic casters on my oil radiator. Without wheels the thing is impossible to move around while its running. These casters are really well built and sturdy and have made this winter so much more convenient. I will buy these again if I ever need casters for anything else.

Description said casters are rated for 150kg/3pcs. Which would make for 200kg/4pcs. Well above my table saw 80kgs. I move the table saw a maximum of 2 meters, a few times per month, on a flat OSB floor. One caster already failed. The stem is not bent. The caster cannot swivel 360° anymore, forcing the table saw into a diagonal motion.
