I tried the ones that you insert with a flat head screw driver but they break. I have always liked
the hex drive and you are only ones that have them.

I'm building a modular toy train layout which I tell myself is for the grand children. These threaded inserts will become the receiver for 5/15" x 18 appliance bolts to be used as leveling devices. Appliance bolts were about 1/5 the price of commercial leveling devices. These hex threaded inserts are perfect for the job.

Best way I found to incorporate adjustable feet on tables. Also use them to assemble projects such as a custom bed frame so it can be taken apart prior to a move.

how deep are the internal threads? how long is the overall length of the insert?
A shopper on Aug 5, 2015
BEST ANSWER: The threads go all the through. This is not a blind insert. Overall length is 13/16"
Best threaded insert to use in 3/4 plywood edge to draw edge into a dado and then be able to take apart and reassemble?
Stewart O on May 9, 2015
BEST ANSWER: If you are talking about inserting these into the edge of the plywood that you will insert into a dado, I would not recommend it. They work by forcing themselves into a hole intentionally drilled too small. That's so that they can mash (as opposed to cut) the necessary threads they need for their holding power. This very action will split apart your plywood. These things work very well for their intended use, in the flat side of a piece of wood, even plyood.
what can i use to thead dowels and the corresponding hole?
A shopper on Aug 19, 2015
BEST ANSWER: To join dowels, I always use the threaded insert with steel hanger bolts. One dowel gets the insert and the corresponding dowel gets the steel hanger bolt and screw the dowels together. Note: be sure to find the center of each dowel before inserting the hardware.

What is recommend hole diameter for the 5/16-18 in hardwood like oak, maple, or walnut?
Mike F on Apr 11, 2016
BEST ANSWER: I wouldn't use this in a hardwood. It is tapered, and a hardwood has little or no give. Rockler has other options where the shaft is straight.
what hole size is required for the 1/4"-20 insert and how deep should the hole be drilled?
Matt T on Jun 24, 2016
BEST ANSWER: For softwoods, 11/32" is recommended, for hardwoods 3/8" is recommended.An 11/32" drill bit is hard to find. Not a standard size.
The hole depth depends upon the connector bolt length. Subtract the thickness of the wood being attached from the connector bolt length, & I add 1/4" to that number to keep from bottoming out.
What is recommend hole diameter for the 5/16-18 in soft wood?
Fran B on Feb 13, 2017
BEST ANSWER: 7/16 in soft wood, 1/2 in hard; use a drop of CA glue when final inserting, works well for me.
How long is the 1/4"-20 threaded insert?
John mc. on Aug 28, 2016
BEST ANSWER: 13/16"
I need to purchase some of these. the ones I removed required a 5/16 hex head allen wrench. Is this, then, the size I need to buy as a replacement?

I like the length
For what I used them, which was putting a bolt in some 3/4" boards, they worked great. I really like the longer length. There was so much more thread. The whole project seems sturdier. They could be a problem in a much thinner board, but I rarely use them in less than 3/4" anyway.

Excellent product and works as advertised in an end grain application. However, the supplied installation sheet needs the table revising to clearly show the correct drill sizes for softwood / hardwood applications.

metal threaded inserts
They are very useful for take apart & reassemble Furniture such as back Paneling of A desk the center panels of A desk that has 2 cases of drawers & a chair opening in center,The panels at the back of the Chair opening need to be assembled with threaded inserts on right & left side so it can be carried to the customers house in 3 peices & reassembled in the house so it will go through all interior doors.

These hex drive threaded inserts worked better than the original ones that I replaced. Much heavier duty so I didn't even have to re-drill the holes.
