## Long description

Spring washer Koelner DIN 127 M10 A2 is a stainless steel split (helical) washer designed for M10 threaded connections. The pack contains 13 pieces intended to add axial tension and friction to bolted joints, helping to reduce the risk of loosening under vibration and dynamic loads. Manufactured to the DIN 127 profile in material A2 (stainless steel), these washers are suitable for applications where corrosion resistance and reliable preload retention are required.
Advantages
These Koelner spring washers provide a simple mechanical method to maintain clamping force in threaded assemblies. Made from A2 stainless steel, they resist corrosion in many indoor and outdoor environments and offer dimensional conformity to the DIN 127 form for consistent performance. Supplied as a set of 13, they are convenient for small repair jobs, maintenance tasks, or batch assembly work requiring M10 spring washers.
Suitable for
Mechanical assemblies and general fastening where M10 thread size is used
Automotive repairs and vehicle maintenance requiring corrosion-resistant fasteners
Machinery and equipment subject to vibration or dynamic loads
Plumbing fixtures and light outdoor installations where stainless steel is preferred
Key specifications
Standard: DIN 127 split (helical) spring washer profile
Thread compatibility: M10
Material: A2 stainless steel (corrosion-resistant stainless grade)
Quantity: 13 pieces per pack
Function: provides axial tension and anti-loosening friction for bolted joints
How to use
Place the spring washer between the nut (or the bearing face of a bolt head) and the assembled part so the split and helical shape compress slightly when the nut is tightened. Tighten the nut or bolt to the specified torque for the application so the washer flattens enough to provide friction and axial preload without over-compressing the material. Inspect assembled joints periodically in high-vibration environments and replace washers showing signs of wear, distortion, or corrosion.
Usage recommendations
Use these stainless steel spring washers in combination with matching M10 bolts and nuts of compatible materials to avoid galvanic corrosion. For critical joints, follow the equipment manufacturer's torque specifications and replace spring washers during reassembly after disassembly or when any loss of clamping force is suspected.
