Yes, I was referring to the T-nuts. Now it makes sense to prevent the bolts from going through all the way. In practice some of the bolts in the kit did go through anyway, which confused me. Anyway, I was trying to mount an adjustable angle table onto the mill table, using just standard 3/8" bolts with heads. That requires bolts of rather precise length, maybe assisted by a washer or two. In this situation it would be easier to find a useable bolt length if the bolt were able to go through the T-nut a bit. OTOH, I could have used a clamp + bolt as provided by the kit, but that would take up extra space. In this case I think I will cut some bolts to fit.
