Rated 5.0 out of 5 by 3 reviewers.
Rated 5.0 out of 5.0 by Very User Friendly...worked like a charm! We purchased these wood screws to use in a Boy Scout Eagle Project. I was worried we would need to pre-drill holes--we were using multiple layers of 6x6 pre-treated lumber for a planter/sustainability project. The lumber was incredibly wet after 15 days of straight rain! The screws were fine on their own. We were able to use a drill to seat them perfectly -- Scouts had no issues getting them in straight - it's a hex head so no stripping. Just make sure you have the correct size hex attachment for your drill -- the drill bit does not come with the screws. June 7, 2016
Rated 5.0 out of 5.0 by wow, talk about a time saver! I had been using lag screws and spikes. Staff at a competitor store didn't know what I was talking about when I asked about these screws. I wasted two days drilling and cutting timbers for my retaining wall. I knew this product was available, so I went to Home depot. The staff knew exactly were the screws where. These screws are amazing. No predrilling. These screws plowed right thru 6 X 6 timbers. I'll be picking more today. Returning lag screws and spikes November 2, 2015
Rated 5.0 out of 5.0 by Works Great!!! I built an 80' 6"x6" timber wall that is 5' high at its peak. 6x6 posts were placed 5' apart with the horizontal timber placed behind it. The Timberlok 10" screws were used to hold everything in place. Worked great with the screws going in with a heavy duty 18volt battery operated drill. I have already recommended Timberlok to a fri HD who is building a similar wall January 26, 2016
