Review on 20 Stainless Steel Standoff Screws - 1/2 X 1-3/16-Inch Mounting Hardware For Acrylic, Glass & Pictures - Lantee Product Review by Ricky Brooks

The quality of these are not very good. There were six pieces that seemed to have a flaw in manufacturing. Some were incredibly lopsided on on side, almost like they got pinched in the machine. Otherwise had very ragged bottoms. Some of the screw tops would not sit flush or uneven so the plastic spacer would disappear in the middle. A couple of them also had small cracks.I would not order again
