Product Overview

Save time, money and labor costs! ThruLok is the first fastener engineered to make a code compliant connection for your 4x4 decking posts and notched carrying beams without pre-drilling! ThruLok is over 15 times faster than the traditional method of installing posts and the only tool required is an 18 Volt drill. No need to predrill, hammer in a 1/2 in. carriage or through-bolt, and hand wrench the nut to tighten on the back. ThruLok zips right in and has a patent-pending encapsulating nut that self tightens on the end saving time and labor.

  • Manufactured in three lengths: 6 1/4 in. - 4x4 to 2x rim
  • Costs significantly less per piece than 1/2 in. galvanized carriage or through bolts, washers and nuts. Save even more money.
  • ThruLok comes preassembled eliminating the need to find different components.
  • Guaranteed corrosion resistance for the life of the project. ACQ approved
  • Free 5/16 in, magnetic hex drive bit in every pack
  • American made

Rated 5.0 out of 5 by 4 reviewers.
Rated 5.0 out of 5.0 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
Rated 5.0 out of 5.0 by The new standard for deck construction Use these for your decking projects and you'll never go back. Easy and sturdy for building decks... October 18, 2016
Rated 5.0 out of 5.0 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 5.0 out of 5.0 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
