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:

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.
