Rated 5 out of 5 by 3 reviewers.
Rated 5 out of 5 by Great product. Quick easy and painless installation. Best replacement for carriage bolts. Saved so much time not pre-drilling 16 connections. Had a harder time finding them in stock. April 29, 2014
Rated 5 out of 5 by way better than any carriage bolt ever I used these for my deck posts and they saved me so much time. they also look great. I would use them agaiun in a heartbeat. April 23, 2012
Rated 5 out of 5 by Great product in every way I needed to bolt a deck/porch beam to four support posts. The cost of the Thru-lok bolts was comparable to what I would have paid for lag/carriage bolts (and washers/nuts). I was able to bolt up all four posts in less time than it would have take taken to pre-drill the bolt holes. I'll never use anything else again. September 28, 2012
