Parts Express Cast Frame #8-32 Speaker Mounting Kit
Parts Express Cast Frame #8-32 Speaker Mounting Kit is rated 4.0 out of 5 by 4.
Rated 5 out of 5 by from Works for mid-sized and small speakers.These #8 T-nuts worked well for mounting some 6.5" speakers I installed into a particle board cabinet. The prongs went in straight; and none bent over as they sometimes can, especially if you are using a wood harder than particle or plywood.Here is one basic method of installation:After cutting the speaker hole to size, fit the speaker into the hole and carefully center-mark the screw locations while keeping the speaker/marks equal distance from the hole's edge, especially if the speaker hole is slightly larger than the speaker mounting dimension. Remove the speaker and drill straight pilot holes using an 1/8" bit. Then, drill through again using a 1/4" bit to enlarge the mounting holes that will accommodate the T-nut shaft fitting into the hole while providing a slight amount of alignment slop. Mount the speaker again, and install the T-nuts and the #8 hex screws until the prongs just touch the wood on the back-side; align the prongs away from the hole's edge as best you can and slightly tighten each bolt using a 9/64" hex wrench (which is sometimes a less available and harder to find size). Tighten the screws sequentially by repeatedly working around the speaker to slowly pull the T-nuts flush to the wood; do not try to do it at one time (don't use a hammer). Note that a #20 Torq-X will work to quickly install/remove the bolts in the future, but I would NOT use it to draw the T-nuts into the wood because it could slip and round-off the hex. Installation per the above allows everything, including the speaker, a chance to self-align. (Note: drill is not shown in photo for clarity.)

Rated 1 out of 5 by from I don't think this worksAt least I couldn't get it to work. It should have some instructions as to how you insert T-nuts. I looked on You Tube and I did what the fellow did there. It didn't work for me. At a minimum, there should be some suggestion as to what size drill to use to sink a hole for the bolt. Then, the kit should include some sort of T-nut insertion bolt because trying to suck it up with a regular #8 bolt ruins at least one bolt per insertion - which bolt does not come with the kit - and maybe many more. A Phillips head drive does NOT cut it, it just get chewed up. I don't then, how you sink the T-nut. And the kit should definitely include small #8 washers.

Rated 5 out of 5 by from Work as advertised, beware when using 3/4" boardSo far I've built two set of speakers, using a total of 5 sets of these. Bolts go through seamlessly through he nut. Placing the nut firmly into the pre-drilled hole is the key for  success using them. If the nut is not firmly attached to the board, then the torque coming from the adjusting bolt will release the nut and the bolt will not hold whatever you are trying to attach. One issue only is that the bolts are not intended for 3/4" board, as the threads will end before the bolt goes through. A little extra torque from your drill will force the thread in the flat part of the bolt. Not a recommended practice, but in my case the bolts seem to be of slightly less hard material than the nut, so the bolt went though anyway.

What size hex key is needed for these? None of my key set seem to fit them.

Asked by: The Kid Slak
A 9/64" hex bit fits them perfectly. A 3.5mm bit would most likely do the trick as well.
