I bought M4 Stainless Flat Washers as part of my camper van equipment.
The roof assemblies made the differences between screws, washers and slot hardware easy to see. This M4 flat-washer pack is another size in my purchased fastening supplies.
Separating Washer Size from the Material Choice
I assembled the light-bar beam with drilled connectors.
The smaller extrusion used M5 hardware and the rack used quarter-twenty fasteners.
My wider hardware purchases included dedicated M4 flat washers alongside other sizes and materials.

My Takeaway from This Job
The roof assembly brought several hardware families to the work area. This M4 pack keeps one metal-washer size together; Glarks adds several metal sizes, while Sutemribor changes the contact material to nylon.
A single metal-washer size and a mixed nylon assortment change two attributes at once.

Profile
Continuous flat disk
A flat washer surrounds the fastener shank and adds a contact footprint beneath the head or nut. Record its outside diameter as well as the M4 size when planning a small van bracket. The available flat area can be limited by bends, panel edges or the nearby screw positions. Keep these continuous disks separate from the M4 split washers so the parts list shows the actual washer shape used at each position in the joint.
The actual outside diameter and thickness still matter when laying out the contact surface.

Two Alternatives to Compare
Glarks provides a multi-size metal-washer assortment. Sutemribor changes the material to nylon and includes several sizes, creating a different contact surface.
This Sutemribor set groups nylon flat washers in several metric sizes. The divided assortment provides different hole sizes in one nonmetal washer kit.
