Keeping Outside Diameter Distinct from Fastener Size
My roof work combined brackets, screws, washers and slot nuts.
The smaller profile and the rack used separate hardware families.
I bought black M6 fender washers as a wider-disk option in the fastening kit.
The profiles and joint hardware during my roof-mount assembly.The drilled connectors and fasteners joining my added extrusion to the roof rack.
My Takeaway from This Job
A change in outside diameter can change the footprint without changing the M6 grouping. These eighteen-millimeter black disks compare with a smaller stainless M6 format and a box containing several metric sizes.
An M6 grouping can include different disk diameters.

Black flat disk
The eighteen-millimeter disk gives this M6 washer its physical footprint. Check that outline against the surrounding hardware as well as checking the central opening against the fastener. In a van panel or bracket drawing, the washer is part of the complete stack rather than an invisible detail under the head. Recording both dimensions keeps these broad washers distinct from smaller M6 washers and from the M5 and M8 pieces in the same parts collection.
