Do these come with the hex socket drill bit?

Asked by Em May 17, 2020
4
Answers

The box says it does, but for whatever reason, in the box I bought, it didn't. I suspect that's a quality control issue. Nonetheless, I'm very impressed with the screws. I used a hex socket from a drill kit I already owned.

When attaching 2x4 to 4x4 post using these screws, should I make leading drilling holes?

I always drill a pilot hole, makes the bolts screw in better. Just don't drill all the length of the bolt.

Will these work for attaching a wood header board to the side of a shed for a roof

Asked by Robert February 12, 2016
1
Answer

Yes they will work for that. The box says they can be used for deck headers, so using it to attach a header to your shed for adding an additional roof would work as well. According to the box, the screws come with a lifetime warranty for corrosion resistance if installed correctly. And people use them all the time for other outdoor projects like fences, decks, and even kids wooden play sets.

Fastenmaster Timberlocks are the best way to go for deck building. These take away far less wood than lag bolts. I had a deck destroyed by a huge tree. Some 2x12s broke at midspan but the Fastermasters held at the posts.

I bought these to replace the screws the builder had used to hold some decorative outdoor woodwork in place, and were now disintegrating. These screws are excellent quality, and should never need replaced. I’ll be buying more as the old screws continue to fail.
