Rated 5.0 out of 5.0 by Great solution for re-anchoring a misaligned mudsill We got these Tapcons to fix a problem with a 2x4 wooden mudsill that had been pushed in by a tree that grew outside the garage and eventually got so big that the trunk started to push the garage wall inwards. After we removed the tree we still had a problem of the mudsill being out of alignment by about 1 1/4" so we needed something long and strong that would re-anchor it in place. After using a hydraulic bottle jack wedged with a 4x4 against our tractor's rear tire to get the mudsill pushed back into alignment, we installed the Tapcon to keep it securely back in place. Reading the Tapcon instructions, they recommend using an 3/8" ANSI drill bit however when I measured the tip on our 3/8" masonry drill bit, it was wider than the 3/8" diameter of the Tapcon bolt and I was concerned that the bolt would not grip if I used a 3/8" masonry bit. As an alternative, I used a 3/8" Lip & Spur wood bit to drill into the wood so I could get at the concrete pad below. I then used a 9/32" masonry bit to get to the necessary depth in the concrete and followed this up with a 5/16" masonry bit. If you're doing something like this, I also recommend having something available to blow the concrete dust out of the bottom of the hole otherwise the bolt won't go all the way in as the dust gets compressed in the bottom of the hole. We used a drinking straw on the end of our compressed air fitting however a can of compressed air would also do as long as you can get the air down to the bottom of the hole in the concrete with some type of directional nozzle. With the holes drilled and the concrete dust blown out, the Tapcon bolt was reasonably easy to screw in using a 1/2" socket and ratchet. I cinched it down snug with little effort and there was no sign that the grip in the hole wasn't strong. We also put some Tapcons in a dividing wall in the garage that only had nails into the concrete and after I mastered installing the first one, the next one took about 10 mins to drill and install from start to finish. According to the Tapcon brochure, at 2 1/2" of depth (about what you end up with when installing into concrete through a 2 x 4 wooden mudsill), the bolt has around 6,000 lbs of shear strength so it should be fine here in earthquake country.

Rated 4.0 out of 5.0 by Got the job done! These Tapcon bolts are big ones and must generally be purchased online - there isn't much need to stock these at the local HD. But I needed 3/8" bolts to install a couple of driveway post lights - the bolts were used for the base into concrete. The only thing was, these are 3/8" at the smooth top end, but wider at the threads. So I had to have the holes in my post base enlarged a couple of drill bit sizes to allow the Tapcon bolts to go through. But once that was done, everything was perfect. Once installed in the concrete these post lights aren't going anywhere. January 27, 2015
Rated 5.0 out of 5.0 by Quick and Easy to Use When vertical support is as important as horizontal support, this is the fastener to use. The installation is very easy: drill; clean; install. Just as easy as that. be sure you have cleaned out the hole of concrete dust. Any material left behind may hamper the holding ability of the fastener. For the larger fasteners (1/4" and larger), I install them with an impact gun. This allows for a quicker set, and heats up the fastener to allow the coating to bond to the material. July 22, 2014
Rated 5.0 out of 5.0 by Great product, easy to use I bought these to anchor the base of a small home climbing wall into the concrete pad of my garage. The product was easy to install and I appreciate the fact that they are removable, unlike other products, should I ever decide to take the wall down. February 13, 2014
