Work well for birdhouses or furniture repair. They do what they are designed to do at a reasonable price. A must have for the carpenter or wood working hobby. Make sure to order to have on hand before starting that project or repair.

Pretty stout threads. I applied a small amount of epoxy when installing....just to be sure..!

I have had a supply of inserts like this for decades. They were brass and when I ran out of those I found these. Great value and thus far easier to use than the softer brass inserts. I use them all over my shop on equipment and on jigs I build. Good stuff.

First off, they work. They are however not easy to install and not busier friendly. Using a flathead tool to install these is somewhat difficult without damaging the insert due to the metal tearing (stripping out). If you use a threaded driver, they are a little awkward to get to seat straight without going in at an angle. A 3/8 inch pilot with a small amount of glue seemed to work well in Baltic Birch ply, alder, and teak woods. I’ll be purchasing Allen driven inserts next time.

Funciona, pero son mejores los insertos con llave hexagonal.

I use these for a product I make and have been very happy. Pay attention to the suggestions for what size pilot hole to use. I use a 9/16ths pilot hole since I'm installing them in hardwood.They do go in crooked if you screwing them in by hand, even with an insert tool. I ended up cutting the top off the insert tool and put it in my drill press, then manually turn the chuck to insert them exactly straight. It took some time to set up but once you have it down its very easy. I've used a few hundred of these by now and love them.

They are a bit tough to install. I first tried using a big screw driver, but the inserts kept going crooked. So I came up with a scheme to use my drill press. I took a 1/4-20 hex head bolt, and cut the hex head off. I then chucked it up in my drill press, threaded a 1/4-20 bolt up to the un-threaded part of the bolt. I removed the belt from the drill press, so I could turn the chuck by hand using the pully. I then threaded one of the inserts onto the bold, lowered the quill, centering the insert over the hole, pressed the insert gently into the hole, and started turning the pully, and the insert went in nice and straight.They have a tool to help with the insert, but I didn't want to wait for delivery, and I'm a bit cheap. This I ginned up in about 15 minutes.

I'm using the 1/4" size for bolt-on guitar necks. They thread into an 11/32" hole. Way cheaper here than big box stores or luthier supply houses.Tip: Threaded inserts are almost impossible to screw in straight if you do it freehand with a screwdriver. Getting one started cockeyed causes all kinds of problems. One trick I use is to cut the head off a bolt that fits the insert. Then screw on a couple of nuts and jam them together with just enough of the bolt sticking out to thread into the insert. Now chuck the assembly into the drill press. Put the workpiece on the table and, with the power OFF, lower the insert into the hole. Turn the chuck by hand to feed the insert into the hole. This guarantees that the insert will go in straight. Turning the chuck the other way will back the bolt out, leaving the insert in place. I keep my little homemade insertion tool with my bits and punches.

Great value BUT.... Much harder to keep straight while threading into wood than the Ez lock version. I think it’s the flat head slot... much more controlled with an allen key type way to sink them into the pilot hole.
