## Summary description

Koelner spring washer DIN 127 for M8 fasteners, made of A2 stainless steel, supplied in a pack of 15. Designed to prevent loosening and maintain preload in bolted joints by providing elastic tension. Suitable for general industrial, automotive and construction applications where corrosion resistance and vibration protection are required.

## Long description

Koelner spring washer DIN 127 M8 A2 is a stainless steel elastic washer supplied in a pack of 15, designed to increase joint reliability by reducing the risk of fastener loosening. Made from A2 stainless steel, this spring washer provides corrosion resistance suitable for many indoor and outdoor environments while maintaining elastic tension under dynamic loads. It is manufactured to DIN 127 geometric standards for use with M8 bolts and screws and is intended for general industrial, automotive and construction applications where preload retention and vibration resistance are required.
Advantages
The stainless A2 material offers good corrosion resistance in common atmospheres and industrial environments, extending service life compared with plain steel washers. The DIN 127 spring shape provides elastic action that helps maintain preload and reduces the tendency of threaded fasteners to back off under vibration or alternating loads. Supplied in a practical pack of 15, it is convenient for small repair jobs, maintenance tasks or stocking spares.
Suitable for
 Securing M8 bolts and screws in industrial assemblies
 Automotive repair and maintenance where vibration is present
 Construction fixtures and fittings exposed to moderate corrosion
 General machinery, equipment and fastening applications requiring preload retention
When it may not be suitable
This spring washer is not intended for use with fasteners that require electrical insulation or in applications needing a specific hardening grade or high-strength alloy beyond A2 stainless. It may be inadequate in highly corrosive chemical environments, marine saltwater immersion, or where traceability to special certification or heat treatment is required.
Key specifications
 Standard: DIN 127 spring washer
 Size: for M8 fasteners
 Material: A2 stainless steel (corrosion-resistant austenitic grade)
 Finish: natural stainless steel surface
 Pack quantity: 15 pieces
How to use
Place the spring washer under the head of the bolt or beneath the nut so that the curved surface faces the loaded surface to ensure elastic action. Tighten the fastener to the required torque for the assembly; the washer will compress and apply tension to help maintain preload. For best results, use with properly matched M8 bolts or screws and ensure mating surfaces are clean and free of debris that could affect seating.
What to consider before purchase
 Confirm the fastener thread size is M8 and that DIN 127 spring washers are the appropriate type for your application
 Evaluate whether A2 stainless steel corrosion resistance is sufficient for the environmental conditions
 Check torque requirements and whether a different locking method is needed for extreme vibration or critical safety joints
Usage recommendations
Use this Koelner DIN 127 M8 A2 spring washer with matched M8 fasteners and standard torque values for general assemblies. Replace washers showing signs of deformation or corrosion and consider upgraded materials or locking solutions for highly corrosive or safety-critical applications.
