It’s a good vise clamp… Only complaint is the box arrived torn & was missing some bolts.
It is ok for med to light duty.
Use bolts under 1/2" dia.(3/8ths or 7/16")and long enough to pass thru both the vise and bench top and leaving 3/4" thread exposed to allow for washer and nut (or nylon-loc nut)
your kidding right--nothings made in the USA-we gave all that work away to foreign hands
