The zinc plated Wedge anchors have very low resistance to rust so outdoor applications are not recommended. We recommend using the hot dipped galvanized Wedge anchors for outdoor applications.

Rated 4.5 out of 5 by 4 reviewers.
Rated 5.0 out of 5.0 by Secured Gazebo posts into concrete. I used (8) Red Head 1/2 in. X 3-3/4 in.concrete anchors to secure 4 Brown Roth 10' X 12' gazebo posts and was so impressed by their strength and ease of installation. I highly recommend this brand of fastener. April 20, 2016
Rated 4.0 out of 5.0 by good for what I needed Anchored a husky 60 gal compressor with four of these. Took awhile to drill out the concrete, but they were easy to install with some rubber anti vibration blocks. The compressor isn't going anywhere now. June 28, 2016
Rated 5.0 out of 5.0 by very impressed Bolted down my gun safe with 4 of these. Very easy to use and the security check that I performed has me convinced that they will deter every thief except those with a crane. The only drawback is that the studs sit up higher than I'd like after installation. I am going to have to take a grinder with a cut-off wheel to get the bolt hole covers back on. March 17, 2014
Rated 4.0 out of 5.0 by Good Product Bought a bunch of these to install some pallet racking and they are very sturdy. June 11, 2013
