Good value
Seem good quality and a good price to and do exactly what they should, you need a powerful drill to put these in and one with a side handle as they go in very tight and the drill can easily kick back on you.

Would not use again.
Tried two bolts. Both broke when being tightened. Feel very light would not use again.
