The Item in My Kit

I bought M4 Stainless Split Lock Washers as part of my camper van equipment.

My hardware purchases include sizes beyond the M5 roof-frame fasteners. This M4 pack is a smaller metric option in the workshop kit, where keeping similar-looking pieces separated matters.

Separating the M4 Supply from the Roof-Frame Hardware

  1. My roof-frame notes identify M5 hardware at the smaller extrusion.
  2. The rack connection used a separate inch-thread group.
  3. My broader purchases also included M4 split washers, kept as another metric size in the hardware kit.

My Takeaway from This Job

Similar-looking washer sizes need separate places in the kit. This M4 pack supplies one size; the Sutemribor and Aienxn alternatives use divided assortments for keeping several metric sizes together.

A dedicated M4 pack and a divided assortment organize the supply differently.

Product Details And Van-Build Uses

SpecificationProduct Detail
SizeM4
MaterialStainless steel
ShapeSplit ring

The open ring and separated ends distinguish this M4 washer from a flat disk. Put the washer shape alongside the size in the organizer rather than storing all small rings under one label. For a van service-access panel or small equipment bracket, record the complete sequence of head, washer, panel and nut. That provides a useful reference when the connection is opened and keeps the stainless M4 selection separate from the larger M5 and M6 pieces.

How Can It Be Distinguished From A Flat Washer?

The split washer is an open ring with separated ends; the flat washer is a continuous disk.

Alternative products

Two Alternatives to Compare

Sutemribor and Aienxn offer multi-size split-washer assortments that include M4. The assortment format trades a single-size supply for several labeled compartments.

Which Hardware Sizes Appeared in the Light-Bar Mount?

Quarter-twenty hardware on the rack side and M5 hardware on the added 2020 profile.

What Slowed Down Starting the Small Bolts?

The loose nuts moved or spun in the channel and needed repositioning.
