The M14 size of Wave Washers (Curved Spring Washers) is dimensioned by DIN 137 B. The table below gives the dimensional row from the standard, followed by the installation notes for this type.
Values are taken from the governing standard rather than from a general machine-thread table, because this type is not selected on one.
M14 Dimensional Row (DIN 137 B)
| Thread size | Inner diameter d1 (mm) | Outer diameter d2 (mm) | Material thickness s (mm) | Free height h (mm) | Reference standard |
|---|
| M14 | 15 | 24 | 0.8 | 2.3 | DIN 137 B |

Need wave washers (curved spring washers) in a size this table does not list?
This page covers M14 wave washers (curved spring washers). Bore and outside diameter are set by the joint rather than by the bolt, which is why an off-table size is so often the right answer. Made by stamping or punching.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

Applications & Industries for M14 Wave Washers
The sectors that buy Wave Washers to DIN 137 B, and the duty each one buys them for. Stocked from M3 to M24.
Industries that specify Wave Washers
-
Machine building & OEM
Setting bearing area on soft alloy, plastic and oversized holes.
-
Timber & construction
Large-diameter washers that stop pull-through in softer material.
-
Rotating & vibrating plant
Spring, tooth and wedge types that maintain or lock bolt tension.
-
Steel fabrication
Spreading load under a head or nut and protecting the surface finish.
Typical applications
- maintaining bolt tension in a joint that settles
- spreading clamp load over a soft or oversized bearing face
- protecting a painted or plated surface under a turned nut
Service conditions to specify against
- Marine and coastal
- Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.
- Hardness matters
- Under a high-strength bolt a soft washer embeds into the joint and preload is lost — specify a hardened washer for structural bolting.
