Review on High-Performance Star Drive Lag Screw for Construction by Darrell Shreves

Revainrating 5 out of 5

They work great but require a pilot hole.

I used these instead of the good old reliable screws because they are advertised as not requiring pilot drilling. I have found that this is not the case. The sprocket works pretty well, but so do the hex heads on the old bolts.

Pros
  • Absolutely amazing!
Cons
  • Slightly snapped
