Recommended Replacement M6 Square Head Carriage Bolt With Flange Nut

Question:

To whom it may concern, I need to identify a source for square-headed carriage bolts identical or close to the one shown here see photos below. Basic Dimensions Head thickness: 2 mm Head Dimensions: 15mm x 15mm x 2mm Shaft Diameter: 6mm Total Length: 22mm can vary, not a critical dimension. Threading: M6 Would also like matching flange nuts. Material: Nonspecific. Do you have something identical or similar to the specified bolt? Or can you suggest an alternative source if you do not carry such a fastener? Thanks

Thanks for all the pictures and the measurements!

I took a look at what we have, and the closest items I was able to find to what you're needing is:

-The Replacement Square T-Bolt for Thule Xadapt12 Watersports Adapter Kit # 853208914,

&

-The Zinc Plated Hex Flange Nut # 185916.

The bolt # 853208914 measures 7/8" long (22.23 mm), has a 3/4" wide head ( 19 mm), and has a shaft diameter of .23" (5.84 mm).

Additionally, the flange nut # 185916 will work great with M6 bolts that have a thread pitch of 1 mm.
