1/4-20 Steel Threaded Inserts

3606-STS

Item No: 3606-STS
 
 

Product Information

Installing solid brass threaded inserts in hardwoods like maple, white oak, or cherry, has always required experimentation to determine just the right pilot hole size to avoid folding over the external threads. The special threads on these solid steel inserts have a beefy cross section designed for use in hardwoods. Just drill the prescribed pilot hole, and with rare exception, the insert will screw right in. Drive these with a metric sized hex wrench, or the appropriately sized driver to install. Made in Germany.

          Comments about 1/4-20 Steel Threaded Inserts:

          Since these are solid steel and not casted, they work much better than the threaded inserts sold by most hardware and woodworking stores. I did increase the pilot hole size from the recommended 3/8" to 25/64" when installing in end-grain maple.

                  I had to use a 25/64" drill instead of the 3/8" in Poplar. The insert wouldn't go in without damaging the surrounding wood when I used the 3/8". Once I used the larger drill, the inserts went right in and hold well.
