Customer Reviews

Rated 3.5 out of 5 by 2 reviewers.
Rated 2.0 out of 5.0 by Room for improvement Could really benefit from a Torx drive head. Out of a small box one was a useless screw with no threads. I would only recommend it because I do not know of a different option. Driving these through Hardi trim then siding and finally into the framing wore out a few drive bits, phillips just isn't the best for torque. September 6, 2014
Rated 5.0 out of 5.0 by Good product pulls rock board into place nicely Good product for the money holds rock board nicely in place February 17, 2012
