What are T-track bolts and nuts, and what size do I need for track accessories?

Expert Answer

T-track bolts and nuts are fastening parts used to clamp accessories into a T-slot track, most often on woodworking jigs, fixtures, fences, and shop setups. The right size depends on the track profile, the slot opening, and the thread size of the accessory or nut being used.

In practice, you need to match three things: the head shape must fit and slide in the track, the thread must match the nut or tapped accessory, and the bolt length must suit the thickness of the part you are fastening. Common setups use T-bolts with matching nuts and washers, but the exact dimensions vary by track system. If you are replacing hardware, measure the slot width and the depth of the track, then check the thread standard before ordering. VANROCK supplies undercarriage parts through an appointed dealer network and can quote on request; for crawler machines we also supply track bolts and nuts, but for T-track hardware you should confirm the application first.
