Dimensional data for M6 Nylon Flat Washers to DIN 125 A, with 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.
M6 Dimensional Row (DIN 125 A)
| Thread size | Inner diameter d1 (mm) | Outer diameter d2 (mm) | Thickness s (mm) | Material | Temperature range (deg C) | Reference standard |
|---|
| M6 | 6.4 | 12 | 1.6 | PA6 | -40 to +100 | DIN 125 A series |

Need nylon flat washers in a size this table does not list?
This page covers M6 nylon flat washers. Bore, outside diameter, thickness, temper and finish are the variables here — there is no thread to specify, so the fit and the bearing area are what the drawing has to pin down. Made by stamping or punching.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

Applications & Industries for M6 Nylon Flat Washers
What Nylon Flat Washers are specified for, industry by industry. Stocked from M2 to M20.
Industries that specify Nylon Flat Washers
-
Electrical & electronics
Insulating and isolating fixings in panels and boards.
-
Chemical & process
Chemically resistant seating under a fastener.
-
Food & pharma equipment
Non-marking, non-contaminating washers in washdown areas.
-
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
- insulating a fastener electrically from the panel
- separating dissimilar metals to break a galvanic cell
- protecting a soft or finished surface under a head
- spreading clamp load over a soft or oversized bearing face
- protecting a painted or plated surface under a turned nut
- maintaining bolt tension in a joint that settles
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.
- Temperature ceiling
- The polymer feature sets the limit, not the steel: nylon softens above roughly 120 °C, so an all-metal locking type is the correct choice on hot assemblies.
- 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.
