When you need items mounted to T-slot extrusions to be square or parallel to the extrusion (e.g. material stops), machining them to fit the t-slot opening is not reliable. The problem is that the t-slot opening widths vary; from brand to brand, from regular to light, even from face to face on the same extrusion.
The solution is round rod T-slot nuts - 1/4" for 20 series extrusions (not shown), 5/16" with a flat for 10 and 25 series extrusions, 3/8" for 15 and 40 series extrusions. While I have only used 8020 extrusions, any similar extrusions (e.g. Faztek) should work.
Where perfectly square or parallel mounting is desired, the nuts have reamed holes to match locating pins (3/16" typ) press fit into the stop or mounting plate. Standard hole spacing is 32mm (1-1/4", free sliding and incremental bases), 1" and 25mm (incremental). Springs, typically blind holes in the nuts, insure the quick and even release of clamping pressure. Nuts with two threaded holes are standard for toggle clamp mounting bases (a flat version for t-track is also available).
Self aligning T-slot nuts are made from smooth, non marring, drill rod or stainless steel. Standard 50mm (~2") nuts, w/ tapped, reamed and spring holes, are $16ea. Toggle clamp base nuts (two tapped holes) start at $10ea. Minimum quantity: 1 for stock sizes, 4 for custom sizes/hole patterns (no extra charge if I can do them.with existing fixtures).
