Below are the dimensions of all holes located in the Ford Transit cargo area. Most of the factory holes are unthreaded, so threaded inserts such as rivet nuts or cross nuts can be used to create threaded anchors. Knowing the holes sizes allows to select the appropriate insert/bolt and prevent “spinners” (that’s when an insert spins and the fastener cannot be torqued/removed). The Transit BEMM (Body and Equipment Mounting Manual) doesn’t show these dimensions, so we went ahead and took care of it 🙂 Hope this helps!

To sum it up, the Ford Transit cargo area has the following unthreaded holes diameters: 0.260″ (6.6mm), 0.299″ (7.6mm), 0.315″ (8.0mm), 0.362″ (9.2mm), 0.374″ (9.5mm), 0.394″ (10mm), 0.433″ (11.0mm) and 0.472″ (12.0mm). The more common size is 0.362″ (9.2mm).

And it has the following threaded holes: M6x1, M8x1.25, M10x1.5, and 7/16-20. The more common size is M8x1.25.

These measurements were performed on our 2021 Transit using a digital caliper and a Thread Checker. You may get different results due to manufacturing tolerances, tool calibration and variability between years.


Ford Transit Cargo Threaded Inserts Sizes


Using the holes dimensions gathered above, we can now determine the threaded inserts types (e.g., cross nuts, rivet nuts) and sizes to use in the Transit cargo area:

Rivet Nut: M4x0.7 or #8-32.
Cross Nut: N/A.

Rivet Nut: M5x0.8 or #10-24.
Cross Nut: M5x0.8 or #10-32 with Tooth Lock Washer.

Rivet Nut: M6x1.0 or 1/4-20.
Cross Nut: M6x1.0 or 1/4-20 with Tooth Lock Washer.

Rivet Nut: M8x1.25 or 5/16-18.
Cross Nut: M8x1.25 or 5/16-18 with Tooth Lock Washer.

CRivet Nut: M8x1.25 or 5/16-18.
Cross Nut: M6x1.0 or 1/4-20 with Tooth Lock Washer and J-B Weld.

Threaded holes:

M6 x 1.0
M8 x 1.25
M10 x 1.5
7/16-20

We can conclude that the most common threaded inserts for the Ford Transit are M6x1.0 or 1/4-20 rivet nuts and/or cross nuts.

  1. Hi, the 2 pictures are showing blacked out for some reason. I’ve tried multiple devices and browsers. I just wanted to give you a heads up.

    Thanks for posting this information, it is very helpful.

  2. Hi! The panoramas don’t seem to be working for me today — I just get black boxes where they should go. Thanks for all you do!

  3. Thanks for taking the time to do this. It’s crazy that neither BEMM nor the Workshop has these mapped out! They have information on absolutely anything else you can think of besides this, and this is an important point for people doing any kind of mounting inside the van.

  4. Hi.
    I fell in love with Van life after my husband left me after 35 year We live happily ever after on Maui And he committed suicide right in front of me. After moving to LA daughter bought ford Tran high/ extended…did NOT know WHAT THE BLANK I WAS DOING. It was insulated with tHINSULATE AND A floor was put in and A back level put up with water containers underneath it. Amateurs were doing it and didn’t know what they were doing either. Nothing else is done what needs to be done first before I go any farther after I’m looking at youR PAGE think I’m seeing this thing about all these rivets and stuff do I need to secure the van IN ALL kinds of places before it gets built …clueless. Please help me.

  5. You guys are truly a god-send I’m more than happy to use your amazon affiliate links to help you get a commission for all the hard work you’ve done to share this wealth of detailed info with everyone! Yet I’m wondering: What length of flanged hex bolts do you recommend? I’m using mostly 1/2” birch plywood for framing, ceiling slats and upper/lower cabinets. Would 35 or 40mm be best? I want to make sure it’s not too long, but also not too short to hold securely… thx!!!

    • The length of bolt depends on the thickness of what you’re fastening, so I can’t really recommend a specific length. There is no “one-length-fits-all”.
      You want enough bolt threads engaged in the threaded insert to ensure secure joint.

      The general rule of thumb for thread engagement is (for steel):
      Fastener diameter x 1.5

      For example, the thread engagement for a M6 bolt is: 6mm x 1.5 = 9mm
      In other words, the bolt length should be chosen so that 9mm is inserted into the threaded insert.

      Hope this helps 🙂

  6. You two are amazing!!! I build homes for a living and love to sleep next to or at my work. I live in a minivan and use my girlfriend’s home as a base to shower, eat, do laundry, etc. I’ve slowly talked her into van life and getting rid of the “over priced” cost of rent and utilities. With that will come a bigger van. Probably won’t go with the Ford because we are both 4wd lovers, so a trail rig van is more our taste, but this is a wealth of knowledge that I’ll use to do my build. I’m pretty proud of what I’ve accomplished in a minivan, I can’t wait to get into a big van! Thank you so much for putting all this out there and mostly for not trying to charge $ for it. You two are saints! There are no words to describe how awesome this is or how awesome you two are.
    THANK YOU!

  7. I wish someone would do this for the Ford Transit Connect. Your interactive diagram has been extremely helpful as many are the same. But the two holes I need to start building my overhead are not the same and no matter what I try, I can’t find the size of that darn hole. I thought it was M6 but even an M4 rivet won’t go in. An M3 will but it’s too small which I verified by setting an M3 rivet nut in it, and it set but plopped right out. I’ve tried every size I have or can find, I’ve been on youtube, google and reading this diagram like a bible, but at this point I don’t know what else to do. I don’t want to drill a new hole as I don’t have the tool and am skeptical I’d be successful. This is a near-new van and i’m trying to use what is there. Any suggestions? It’s the hole on the sliding door jam, all up and down the door jams are the same size hole and are the ones I can’t size. For the full size Transit, your diagram says they are M-6. Not on the connect though. Pulling my hair out.

  8. Good going both of you. Giving the price of B Class motor homes your option is far better dollar wise and building a unit that meets your own requirements plus another hobby sort-of…. Félicitations et au plaisir de se voir aux Fêtes.

    • I started working on it, but I’m struggling because that’s a LOT of information to fit on a sheet of paper. It quickly becomes unreadable… I’ll see what I can do!
