Faztek 15 Series Carbon Steel Economy T-Nut with Black Zinc Finish, 1/2" Width, 1/4-20 Thread (Pack of 25)

This nut is an od size, not fitting the standard aluminum-extrusion T-tracks. The dimensions of the nut are 0.509" w x 0.812" long x 0.128" thick. Rockler T-track, for example, has a slot 9/16" wide (0.5625"), but it is 3/32 (0.9375") thick. The rest of the slot, and Woodpeckers' slot is 7/16" (0..4375") x 9/32" (0.281") deep. with a 3/8" (0.375") lip.Other than the dimensions not being in the description, the part is well made, but won't work in my metal T-tracks without modification. It will fit without modification in a typical T-track routed in wood or MDF. The black oxide coating seems excellent, and the threads are well formed, and offset from the center, as shown in the product picture.

My primary complaint is not with the part itself because it was good quality. My promlem is with Amazon, they do not provide a sketch showing shape, dimensions and the thread data. Why does it matter? So one can confirm that Amazon got the description correct and it is really the part I wanted.
