  • Works great
These inserts are a good quality and have Allen wrench which is handy

  • Easy and reliable.
Size: 1/4" - 20 x 25mm
Good quality. Work great for installing subwoofers. And affordable.

  • Good product but…
Good quality and well described except for one very important aspect. The internal threads do not come all the way to the top of the insert. Obviously the threads can’t because the top of the insert’s has been shaped for the allen wrench to fit into. The allen wrench sits down into the insert about 3/16”+/- before the internal threads start. Keep that in mind when figuring the length of the bolt you want to screw into the insert. ... show more

  • Works as expected
These worked great for me. I didn’t have any need to “retap” as other reviews have stated. I used the EASTLO 1/4-20 1 1/2 inch bolts, purchased here on Amazon, and they worked fine. To install the inserts I used a 3/8 drill bit, and then rolled the insert in Minwax paste finishing wax to ease the passage. No complaints. ... show more
