Log home builders first used this innovative timber screw to anchor one log to the next, but deck builders, landscapers, contractors, and others needing an easy driving, heavy duty fastener have quickly adopted it as their own. Extra deep threads maximize holding power in softwoods, while the diameter of the hex drive head is small enough to “bury” itself yet large enough to provide plenty of clamping force. Each timber screw has about 2" of thread. Select a screw that is approximately 2" longer than the thickness of the material you are fastening through for best results. A slippery black epoxy coating provides the corrosion resistance to pass a tough 25 cycle Kesternich corrosion test with less than 15% red rust. Use of these screws in Redwood or Western Red Cedar is likely to result in discoloration. 5/16 Hex Head. Made in the USA.

About Me Avid Do-It-Yourselfer
I used the 6 and 4 inch Timberloks to attach a partial replacement of a white oak threshold. I wound up driving them through 4 inches of pre-drilled holes in the replacement oak and about 2 inches into the remnant of the existing white oak threshold. I used beeswax for lubrication and the hex head made it very easy to drive the screws home. I used a Festool C12 drill and it was strong enough.
Excellent Timber Screw
By Mike

I've built two outdoor structures (a pole-type firewood storage shed and an outdoor shower) using heavy timber - both rough cut and pressure treated lumber - and these screws are the right fastener for the job! They're very strong, have superb gripping power and do not chip or rust. You really need a 1/2 hp drill for installing these. They're a bit pricey, but nothing works better for fastening timbers, posts, or heavy full-dimensioned rough cut lumber. I wouldn't use anything else!
