ThruLOK vs. Through-Bolts

In this short comparison video, see how much time is saved installing a ThruLOK vs. a carriage or through-bolt.

ThruLOK Through Bolt Replacement

ThruLOK is a multi-purpose structural wood-to-wood fastener that replaces carriage or through bolts. It is perfect for specific applications such as multi-ply beams, girder trusses, deck posts and many places where a traditional carriage or through-bolt is used.

Applications

The ThruLOK system combines the strength of a through-bolted connection with the speed of a LOK fastener with no predrilling required. It can be used for applications including:

  • Multi-ply beams
  • Deck posts
  • Carrying beams and more.

Carriage and Through-Bolt Replacement

  • ThruLOKs replace traditional carriage and through-bolts in applications ranging from 4½”– 9 ½”.
  • Its three-part assembly includes a screw, featuring the patent-pending Paddle Point™, engineered washer, and LOK-Nut.

Features

  • Installs with an 18 volt cordless drill
  • No drill bits or wrenches required
  • Galvanized coating meets IRC ACQ corrosion requirement
  • Lifetime performance guarantee

Code-Compliant Connections

ThruLOK is code-compliant when attaching decking handrail posts and carrying beams.

ThruLOK is tested and supported by engineering data that conforms to the most current ICC standards. It is also approved for use in ACQ or treated lumber.
