I bought Hillman Quarter-Inch Stainless Split Washers as part of my camper van equipment.

Keeping the Inch-Size Washer Group Together
I used quarter-twenty bolts at the rack connection.
My light-bar notes list lock washers and flat washers in that hardware stack.
I kept the M5 pieces for the smaller extrusion as a separate fastener group.

My Takeaway from This Job
The inch-size hardware deserves its own group in the kit. Hillman, Cionyce and IMScrews all offer quarter-inch stainless split washers here, so the pack and supplier are the differences rather than a new ring geometry.
These quarter-inch alternatives retain the stainless split-ring format.

These stainless split washers remain a separate selection from the zinc-plated steel and smaller metric pieces in my supplies. Label the material and inch size together so the organizer preserves that distinction. For a van hardware stack, include the washer profile beside the head or nut in the connection drawing. Keeping the actual product reference with those details makes later replacement more precise than choosing a similar-looking ring from a mixed parts bin.
These stainless-steel washers use a split-ring shape with offset ends. Their quarter-inch size provides a washer format for threaded hardware assemblies.
