T-tracks provide variable mounting points for jigs, hold-downs, featherboards, and other accessories. You cut them to the desired length and install them flush with your work surface, using flat-head screws.  With the track installed, you can secure your jig or accessory to your work surface with T-bolts or 1/4″ hex head bolts paired with nuts or threaded knobs.

T-tracks commonly measure 1/2″ deep, 3/4″ wide, and 12″ or 48″ long. Tracks with these dimensions accept T-bolts or 1/4″ hex head bolts, while larger tracks accept 5/16″ fasteners. The deeper trench of the Incra T-track, shown above, conveniently accepts bolt ends and nuts as well.


If you secure your jig with hex head bolts, you’ll have to slide them in from the end of the T-track, which can be a PITA if you’ve already got accessories in place.  T-bolts, on the other hand, you can install at any point on the track — just insert and rotate.  You might have more trouble finding them locally, though.

Whichever bolts you go with, threaded knobs maximize the ease of using your T-track.

    Thanks for the link. I’ve been looking for some of these for some jigs I’m making for the table-saw. I didn’t see them walking around my local hardware store or the big box.

  2. I wish I knew about this earlier. I was looking for a way to mount some cable assembly fixtures to a workbench. I settled on channel strut (Unistrut) cause just about everybody carries. Though I’m locked into using nuts designed for the channel.

    The easiest source of T-bolts is in the plumbing isle. Just get the bolts designed for holding down your toilet. They are brass so it’s harder to screw up your AL T-track, and often cheaper that true T-bolts.

    As to where to find the T-track, Rockler sells a starter kit which comes with a 4′ length of track as well as a whole bunch of T-bolts and knobs.

    This morning (1/13) I got an email from Rockler that has their T-track kits on sale – Buy 1 get 1 free.

  5. Well, those kits have been on sale for a few days now. It’s a pretty good deal, but the lack of free shipping is disappointing.

    Also, it seems to be fit for 5/16″ hardware only. You don’t need to buy two, one unit is still on sale, but if you’ve got to pay for shipping, one may as well purchase two.

    I still prefer Incra’s T-track styling since it accepts 1/4″ bolt heads.
