Why I Bought It

M5 Stainless Flat Washers appears in my build materials and equipment for this work.

My roof-equipment hardware included M5 fasteners for the added 2020 extrusion. The washer, bolt and slot-nut choices formed separate parts of those small connections.

Keeping the Washer Choice Separate from the Slot Hardware

  1. I used M5 hardware on the added 2020 extrusion side of the light-bar connectors.
  2. The rack side used a separate quarter-twenty hardware arrangement.
  3. I repositioned the small slot nuts with an Allen key when they moved while I started the bolts.

My Takeaway from This Job

The small connection involved separate decisions about the washer, bolt and slot nut. The assembly photographs make that hardware stack visible, while the diary records the extra time needed to align the nut behind it.

The profile, connector shape, bolt and slot nut all contributed to the assembly sequence.

Product Details And Van-Build Uses

SpecificationProduct Detail
SizeM5
MaterialStainless steel
ShapeContinuous disk

These flat disks belong to the M5 hardware collection, alongside screws and separate split washers. A bracket drawing should show the washer footprint around the hole, not only the bolt passing through it. For a van cabinet or extrusion accessory, compare the disk with the available flat surface near bends and edges. Keep the selected washer thickness in the parts stack so the complete joint can be reproduced after taking it apart for panel access.
