LM 2.5 with Sienci t-track. Want to get toe-clamps. Units on Amazon do not fit Sienci t-track dimensions. Advice? Thanks
Do you have any additional details? ‘Units on Amazon’ is pretty vague. How many variations did you purchase and try? Do you have the dimensions or links for us to compare?
The Sienci Labs T-Tracks should accommodate 1/4”-20 hex bolts as stated on the description page.
You can replace the t track bolts. They are available in various sizes for both the bolt head and thread.
Sienci T-track width to hold bolt “head” is 11.3 mm. On Amazon: Genmitsu Upgrade Aluminum Mini Vise Toe Clamp 4PCs, High-Precision CNC Router Clamp for Woodworking & Metalworking Milling Project, Size 56 x 22 x 21mm, Low Profile. The “head” is 16mmx15mm, which is too large.
I was going to suggest using t-nuts but they are 12.7mm in width. Maybe you can grind them down. They would require a 1/4"-20 bolt though.
Or look at the t-tracks that Lee Valley sells. Their width are definitely at least 12.7 mm. That’s what I have in my Altmill. I can measure the width when I get back home later tonight or tomorrow.
They also sell t-tracks for 5/16" bolts. Maybe those are 15mm inside width.
What type nut and bolt are in the toe clamps?
Never mind. They use M6 bolts.
Why not just change the t-nut that comes with the toe clamp for regular m6 nuts?
Thank you for suggestions. Seems replacing the Genmitsu nut with a regular M6 nut is the most practical approach. M6 nut takes a 10 mm socket, so should fit.

You don’t want it to only fit in the slot, it also needs to lock in place when you turn the bolt. Ideally, the distance between two vertices is more than 11.3 mm while the distance between two edges is less than 11.3 mm
