The Item in My Kit

I bought binifiMux Black M5 Fender Washers as part of my camper van equipment.

M5 was the small thread family in my roof-extrusion notes. This fender-washer purchase adds a wider contact option within that same general hardware size.

Adding a Wider Disk to the M5 Purchase Selection

  1. My light-bar notes identify M5 hardware at the smaller extrusion.
  2. I used quarter-twenty hardware at the rack side of the connection.
  3. My metric washer purchases included black M5 disks with a fifteen-millimeter outside diameter.

My Takeaway from This Job

The M5 label identifies one grouping, while the disk width adds another choice. This wide black pack, the stainless M5 pack and the mixed-size Glarks assortment organize that choice differently.

The M5 designation and fifteen-millimeter outside diameter describe different dimensions.

Product Details And Van-Build Uses

SpecificationProduct Detail
Fastener SizeM5
Outside Diameter15 mm
FormBlack flat disk

The M5 opening and fifteen-millimeter outside diameter describe two different washer dimensions. The outside disk needs room around the hole, including clearance from nearby brackets or panel edges. For a van hardware stack, draw the washer with the screw head and attached material so the contact footprint is visible. Keep the size combination in the organizer label rather than grouping every washer that fits an M5 screw under one description.

What Does The Outside Diameter Add?

It identifies the washer footprint around the hole, separate from the M5 fastener size.

Alternative products

Two Alternatives to Compare

The stainless M5 pack offers another flat-washer form. Glarks supplies a range of metric sizes in one assortment instead of a single wide M5 pack.
