M5 Fender Washers is the m5-thread variant of Fender Washers manufactured to DIN 9021. This page focuses on the data engineers reach for at the bench: dimensional values for the M5 size, the spanner/drive that fits, and the assembly data you need to install it.
M5 Dimensional Row (DIN 9021)
| For bolt size | Inner diameter d1 min (mm) | Outer diameter d2 max (mm) | Thickness h (mm) | Reference standard | Notes |
|---|---|---|---|---|---|
| M5 | 5.3 | 15.0 | 1.2 | DIN 9021 / ISO 7093 | Oversized OD for bearing on soft materials |

Installation Tips for M5 Fender Washers
- At M5 the joint is sensitive to over-torque — use a torque-limiting driver and check the head doesn't bury into a softer counterpart.
Mating Parts for M5
A M5 flat washer pairs with a M5 bolt/screw and matching M5 nut.
When to Step Up or Down from M5
When the joint preload approaches the proof load of M5 class 8.8, step up to M6 class 8.8 (or move to M5 class 10.9). When the joint is over-specified, M4 often saves weight and cost without losing the safety margin.
