I built my Tumult enclosure. When it came time to use t-nuts and machine screws I used some #8-24 t-nuts and screws that I had on-hand and I bought some addittional t-muts and machine screws at a local big box home improvement store. Initially, #8-24 machine screws were common locally. I had to get some more screws and t-nuts because a t-nut and screw stripped. I did not want to re-use several of the machine screws because the heads were showing signs of wear. Now, no #8-24 screws are available. Not only are they not in stock at the big box retailer and a local hardware store, the labels in the bins are no longer there. It appears that no local retailers carry these t-nuts and screws. I already have the t-nuts mounted in a box. What can I do? I thought about converting to threaded inserts. but there is very little meat available in the driver recess. The driver is a Tumult and I used a cutout of 14.125" (this is what was recommended, but is a little large.) There is less than 1/4" space between the #8 screw hole and the edge of the recess. I will appreciate any input in this matter.
