BokWin4Pcs M12 Adjustable Leg Leveler Feet, 2.2" Dia. Base Heavy Duty Non-Skid Leveling Screw Leg, Carbon Steel Shockproof Self Leveling Feet for Furniture, Workbench, Machine (Orange)

These are very good, but the travel is a bit short; no problem if you're close to begin with. If you have something fairly heavy, you can smear the soft pads right off of the feet. This is no fault of the feet. The pads can be easily reinstalled. With weight, they grip on concrete like they're glued down. Perhaps it's best that you don't drag your bench with these installed. My bench is about 600 lbs. I would definitely get these again. You will need M12 flanged inserts if you're going into wood with the studs.

My bench grinder is mounted on it’s own stand and had a lot of vibration. This product eliminated 90% of the problem! Would definitely buy again!

Needs to have another nut and washer added to be an effective leveling pad.

These are well made feet but not really levelers. Extra hardware is required to make them levelers. Rubber bottoms were cupped, not flat.

Used these on a mobile base for a heavy table saw. Worked great

Feet seem sturdy but 4 nuts were missing, so now I need to leave the house, deal with traffic and try to track down a metric nut😡

Note: to make these adjustable feet - you will need to purchase 1 12mm nut for each foot...as it only comes with 2 nuts (three are needed).Really happy with quality on these

I used 8 Of these to set up a 1,200# machine. I added extra nuts and washers, but still good for the price and leveled the lathe. They look pretty good too.
