Save time, money and labor costs! HeadLok eliminates the need to predrill and hand-ratchet in 3/8 in. galvanized lag screws in wood-to-wood projects. HeadLoks aggressive threading and sharp gimlet point allows it to zip right into wood or OSB without pre-drilling. Plus, the wafer head eliminates the need for washers and offers increased pull through strength. Perfect for deck framing, stair stringers, fencing, cabinets, and more! Sizes are perfect for virtually any dimensional wood-to-wood project.

  • Nationally code compliant. Stronger design shear values than 3/8 in. lag screws
  • No pre-drilling. Zip right in
  • Patented spider drive virtually eliminates cam-out
  • Guaranteed corrosion resistance for the life of the project. ACQ approved
  • Free spider driver bit in every package
  • American made

Rated 5 out of 5 by 2 reviewers.
Rated 5 out of 5 by Great! Hard to believe these are as strong as a 3/8 lag and are so easy to use. They do a great job of pulling the joint tight as well. May 20, 2014
Rated 5 out of 5 by Great sturdy product. I used these to screw 4x6 cedar boards together to make a raised bed. It was very easy to screw these in without predrilling even! Didn't have any trouble at all on this project. November 17, 2011
