Quarter-inch stainless flat washers were included in my mounting-hardware purchases.
The featured Amazon option is M6 Stainless Flat Washers.
Where it fits my build
I cut and drilled aluminum bracket pieces for the roof cameras and lights. The camera mounts needed additional holes and adjustments as I brought the assemblies together on the extrusion.
I sprayed the camera-mount pieces with black bedliner during the fabrication sequence. The coated brackets then formed part of the roof camera and light arrangements shown in the diary.

My build notes
The black finish was one stage within the mount fabrication. The holes and profile connections still determined where the pieces could sit, so the diary records the drilling and fitting alongside the coating.
The bracket shape, drilled holes and coating were separate parts of finishing the mount.
Alternative products
Two alternatives to compare
The featured metric washers, black-oxide steel washers and metric assortment show different sizes and finishes. Their bore size and outside diameter define the bearing surface available around a fastener.
Black-Oxide Steel Flat Washers
These flat steel washers sit beneath a screw head or nut. Their wider bearing surface spreads contact around the fastener hole.
