122PCS 1/4'' 5/16'' Furniture Threaded Inserts Nuts Screw,Wood Assortment Tool Kit

These thigs work pretty well! Yeah they arent stainless but unless you are in an extreme environment who cares! Used them on a butcher block top to make a workbench. I did this so I could remove the top and reattach without worrying about blowing out the holes if I need to break it down. I used a 3/8" drill but and a depth control collar on my drill to make sure they went in the right depth. I know others mentioned using either slightly smaller or bigger, after doing some trials 3/8 worked best for me, much smaller and they didnt want to catch a thread, bigger and you risk stripping out the hole. I did make a smaller pilot hole for the larger bit so it didnt drift and it worked great! Driving them in with the supplied hex key worked well, if you have hex bit aoxkets might be a bit easier on your hand. I would recommend these again to someone who is future proofing a project!

These are 3/4” long, 1/4 20 thread insert nuts. Drill a 5/16” hole, drive in the nut using the allan wrench provided, and ready to use. Good inset nuts

You get 90 pieces of 1/4-20 Threaded Inserts for Wood for $29 is a decent deal . And it comes with the wrench to install. The inserts are fully threaded unlike many you see on the market and they offer a choice! I checked the inside threading, ¼ -20 threads in without issue. They look to be zinc coated carbon and they are magnetic, stands to reason that is what they are. I have used other inserts and like the hex drive vs slotted, and I think you get a strong insert for a great price.

Quality piece with no sharp burrs, and include a nice allen wrench for installing. Have used over a dozen and haven't come across any threading issues yet.

Mounted in deer antler so can put on small boards. Used for hat racks
