    The information on what we can use to bolt stuff on our rails is scattered all across the forum. I think it'd be useful to many of us if we had a topic dedicated to that, now we have one :)

    We can use this thread to post information on what works, what doesn't and what might, who makes it, where we can find it and what are the part numbers.

    The 4 options that I know of are:

    T-Slot Nuts
    [​IMG]


    T-Bolts

    [​IMG]


    Unistrut Nuts (w or w/o spring)
    [​IMG] [​IMG]


    Square Nuts

    [​IMG]

    If you know of other things that would work please post them or send me a PM and I'll add it to the list above. I will use the remainder of this post to maintain a list of manufacturers and distributors. Again feel free to send me any information you have about finding these things where you live and I'll update the list.

    I'm in Canada and it's sometimes hard for us to find this kind of stuf. I know some of you guys found Unistrut nuts at home-depot but Canadian hardware stores don't have this kind of stuff, not in Montreal anyway. I will put (USA), (CAN) or (USA, CAN) beside manufacturers names to show if they have known distributors in those countries.

    Things that work


    The big guys nut with modding :)
    Fastenal Part Number: 0189531
    The 1" wrench size makes it tight fit in the rail but unfortunately it's too thick to slide it in. Grinding about 1/4" or 5/16"off of it would probably be enough. It would also probably require access to a 5/8 tap to repair the tread if grinding breaks it.
    [​IMG]

    [​IMG]


    The big guys Bolt with modding :)
    Fastenal Part Number: 20305
    With the 15/16" wrench size makes it the perfect fit for our rails. If fits in tight enough to prevent "jigging" up and down while being loose enough to make it easy to slide. Unfortunately it's too thick to go over the screws in the rails but a little grinding will take care of that easily. The thread is a tiny bit tight in the gap on the rail but it's not enough to damage either and it makes it more sturdy.

    A combination of this bolt with the big nut above makes a nice big attachment.

    I haven't ground the head yet and couldn't insert it any further because of the screw in the rail.

    [​IMG]

    [​IMG]

    The 9/16" T-Slot Nut
    Fastenal Part Numbers:
    Jergens - 0349555 - Not tapped through
    TE-CO - 302932-130481 Not Tapped Through
    TE-CO - 3163956 - Tapped Through

    Made by Jergens but other manufacturers make similar ones. This one is near perfect, the entire nut at 7/8" easily slides in the rail and clears the screws easily, no grniding is required. The 9/16 slot slize is almost the same as the gap on the rail and almost fills it. A 15/16" nut with a 5/8" slot would be perfect.

    A nice bonus is that it also fits nicely in the notches on the rail which makes it even better to lock them in place and stop them from moving.

    [​IMG]


    Things that don't work (or not too well)


    The 1/2" T-Slot Nut
    Fastenal Part Number: 302931-130481
    This doesn't work very well, the Slot is to thin and it makes it loose in the rail, I wouldn't trust except for very very light stuff. The picture below shows how loose it is compared to the 9/16" above.
    [​IMG]

    The 1/2" Hex Nut
    Fastenal Part Number: 373990
    Although it's a 7/8" wrench size it is much too small for the rail. It obviously fits the rail but its hexagonal shape allows it to turn inside which could ultimately loosen the bolt if there was a lot of vibration (like driving on washboard). A larger wrench size would prevent that but then it wouldn't fit in the rail so any hex nut is out.

    I don't have any picture of the nut in the rail, I didn't think it was worth taking one since it doesn't work.

    Unistrut style nuts (not official unistrut) are now at Lowes in Ontario. I am not sure if Lowes has made it to Quebec yet.


    I used 1 inch stainless washers and 3/8"s bolts to attach my ladder rack. The 1 inch washers fit in the notches of the rails.

    Looking!
    Ordering some T-Slots from McMaster Carr next week. Looked it up in a catalog, will post the stainless steel number next week. I looked online, but the SS ones I found at mcmaster.com only show partial threading.

    The partial thread on the McMaster's is actually what prompted me to search other manufacturers. There's a note on TE-CO's site about their T-Slot nuts that says the last thread is incomplete. You need to get the part numbers that end with a T for tapped through ones.

    41409 = Partial thread
    41409T = Tapped through



    @Crooked Beat: I'm surprised about your 1" whashers, I didn't think there was a full inch free inside the rail, I keep looking for 7/18 stuff. That's helpful, it give us more options.

    I wonder if some of these would work. I see three ways of using this if it fits.

    First: All inside the rail with flange facing toward the inside of the bed.

    Second: Inside the rail with the flange facing outside of the bed and the nut's head through the rail. That's the one I doubt most. I don't think they'll have one with a nut head small enough to fit in the gap but with a flange large enough to firmly rest on the inside of the rail.

    Third: Either inward or outward but with the flange slipped inside the rail notches, assuming of course they have one that's thin enough.

    I think the 41603 or 41604 might actually work.

    A normal Carriage bolt works also. I used a two 1/2"x4" ones to mount my high lift. Easy to find also...

    My local Home Depot has spring nuts (unistrut like) in the electrical dept. A bag of 5 was like $3.80. It takes a bit of cutting/grinding to trim them down to 1", but they worked great and are easy to get.

    Ahhhhhh....the electrical department! :confused::)

    I read in another tread that HD had these unistrut-type nuts....so I spent/wasted a pant load of time this morning looking in the bolt sction, the specialty bolt section, and then the strap aisle. :goingcrazy:

    But I never thought to look in the ELECTRICAL DEPARTMENT! :facepalm:

    That would make it a little easier, but I think it would stand out like a sore thumb. The Unistrut is quite large.

    I'm curious to know which options of threading/bolt size are available in the T-slot nuts that will fit our bed rails. The only time I ever remember to measure the rail is the middle of the night when I'm online before bed. :eek:

    Subscribed for updates. Thanks for bringing all the options together in one thread.
