Product information

Description

Koelner spring washer DIN127 M6 in A2 stainless steel is a split lock washer designed to increase axial tension and reduce the risk of loosening in threaded connections. Supplied as a pack of 18 pieces, this washer is suitable for use with M6 bolts and screws where corrosion resistance and reliable clamping are needed. The A2 stainless steel construction provides moderate resistance to rust and is appropriate for standard indoor and outdoor applications that do not involve aggressive chemical exposure.

Advantages

The split ring design offers consistent locking performance by biting into the mating surfaces to resist rotation under vibration and dynamic loads. A2 stainless steel ensures a durable surface finish and improved longevity compared with plain steel washers in humid or mildly corrosive environments. The standardized DIN127 shape and dimensions make these washers compatible with a wide range of M6 fasteners and simplify replacement and inventory management.

Suitable for

General mechanical assemblies and machine construction
Automotive repairs and maintenance
Household fittings and furniture assembly
Electrical enclosures and light structural connections

Key specifications

Washer type: split spring (lock) washer
Standard: DIN 127
Nominal thread size compatibility: M6
Material: A2 stainless steel (austenitic, corrosion-resistant grade)
Pack quantity: 18 pieces
Typical finish: natural stainless steel surface

How to use

Select the spring washer for use with M6 bolts or screws and place it between the nut or screw head and the mating surface with the split and raised edges oriented to engage the fastened parts. Tighten the fastener to the prescribed torque for the joint while ensuring the washer seats evenly; the washer will impart axial preload and friction to reduce loosening. For assemblies involving coated or soft materials, verify that the washer's contact edges do not damage the surface.

Usage recommendations

Use A2 stainless spring washers in environments with moderate humidity and atmospheric exposure. Avoid using them in highly corrosive environments (chlorides, acids) without selecting a higher corrosion-resistant grade. For critical or safety-related joints, follow applicable torque specifications and consider complementary locking methods where required.
