    Default TE-CO (slot question)

    Hi,

    I can't see to find the correct SIZE based on the specs listed on the dealer sites. I need to order some TE-CO's for my 12" Bison RT. I wasn't smart enough buy them when I purchased the RT. <duh> The "top of the slot" in the RT measures 15/32" in width, the bottom where the t-nut goes measures 25/32" and the overall height is 26/32". I'm also not smart enough to figure out what size T-slot nuts to buy? Do sizes go by the top slot or the bottom T-slot? Looks like the ones below are a touch to large in some measurements (like the base width and overall height)?

    The TE-CO specs for a 1/2" are:

    3/8-16 FOR 1/2 SLOT USA T-SLOT NUT TAPPED THRU
    Type: Tapped Thru
    Slot Width (Inch): 1/2
    Thread Size: 3/8-16
    Slot Height (Inch): 9/32
    Overall Length (Inch): 7/8
    Overall Height (Inch): 1/2
    Base Width (Inch): 7/8
    Material: Carbon Steel
    Finish/Coating: Black Oxide
    Manufacturer Part Number: 41405T

    Are these the correct ones I need?

    SD,

    The information I have says that 3/8 T-slots will be .438 - .448 wide at the top and .719 - .781 wide at the bottom so those should be the ones you want. I think the 7/8 figure is probably how long they are.

    Enco and others often have specials on T-bolt sets. Probably imports, but mine have worked for everything I've needed.

    RT t-slots seem to be oddball. Your dimensions sound like my Troyke's. I ended up making some. Easy enough to do especially if you do a long section of tee before cutting them up to length.

    Sounds as though they may be 7/16" T-slots. Reid Tool sells 7/-16" T nuts. www.reidtool.com

    I was thinking about enlarging the slots on my Hendey Shaper till I noticed that jtsmachine.com has them in stock. So I'm going to get some to make up a set of holds for it.

    If you go to there site you can get there big catalog.Not related to them or nothing else, Just a satisfied costumer..
