Searchng For Hard-to-find Bolt

@TURBO200R4 I want the broader head as well. The non-flanged bolt in the picture has a 14mm head diameter and is the size the flanged head would be after grinding down. I want the wider head that is 17.8 to 18mm wide. No one makes that head size standard except in that flanged style so that will be the route I take in the near-term.

bigger head will be special, we used to do stuff like that and it was minimum box of 100

This is an issue with commercial door hardware as well, screws and bolts sometimes have head sizes that are used nowhere else that I know of. Hinge screws have oversized heads that you can't find anywhere else.

Sweet! And they offer it in a black finish, which will match the black backrest. The head doesn’t taper at the edges of the head like the OEM, but it an extra 2mm wider than most bolts I am finding and stainless in black. Winner! (With ~$30 in shipping for the $5 order, such is life).
