Review on 🔧 Enhancing Efficiency with Z Threaded Hex Flanged Internal Threads by Reginald Holman

If you use them in pine or other softwood you will find that they are easy and painless to use as long as you don't drive them in hard enough to split the wood. If you want to install them in hardwood, they may break during installation. I used them to install eight anchors in a solid wood countertop. I slowly used a 10mm allen key with hand tools. Two pulled out about 16 inches before they were flush. (I drilled the holes to 1/2" and spent enough time screwing in and then unscrewing the inserts to reduce the overall friction.) I was able to snap off the rest of the ring with pliers and leave the threads stuffed. to the table I finally settled on an approach that seemed to work better: I started the anchor with a socket head and then threaded the bolt all the way into the anchor, I would then use the socket to turn the bolt by turning the anchor .Once the anchor was in I broke the bolt out with a quick hit of the wrench handle on the bolt.Note that this approach will result in the bolt binding and a slower attempt to unscrew the bolt will result in loosening the anchor pulls back too. I suppose there is also a theoretical point where the anchor can break, but I haven't come across that. A quick hit to break the bolt h prying it out seems to work fine. (I've tried this on my last two anchors and both have worked well.) In conclusion, if you can slip through, don't use them. If you're working with softwood, it should work just fine. When working with hardwood, be careful. (Context: I'm not a woodworker. It's possible I missed another trick.)
