Premium M2-M64 Spring Washers: Superior Anti-Loosening Solutions
Our M2-M64 Spring Washers, frequently referred to as Split Lock Washers, are critical components in any assembly subjected to vibration, torque, or thermal cycling. Engineered with a helical spring design, these spring lock washers apply a constant tension against the nut and bolt head, creating friction that prevents the fastener from backing off. Manufactured strictly to DIN 127 and DIN 7980 standards, our washers provide the essential “spring force” required for safe and durable mechanical connections.
As a leading spring washer factory, we offer a vast range of sizes from M2 to M64, available in high-tensile 65Mn Spring Steel and corrosion-resistant 316 Stainless Steel.
- Effective Vibration Resistance: The split ends of the washer dig into the nut and the mounting surface, physically resisting rotation.
- High Elasticity: Made from premium 65Mn or 70# steel with professional heat treatment to ensure maximum spring back and tension.
- Precision Standards: We provide DIN 127B (Flat Ends) for general use and DIN 7980 (Square Ends) specifically for use with socket head cap bolts.
- Superior Coatings: From Dacromet for 1000H salt spray resistance to Black Oxide for a professional industrial finish.
| Size | ID (mm) | OD (mm) | Thickness (h) |
|---|---|---|---|
| M6 | 6.1 mm | 11.8 mm | 1.6 mm |
| M8 | 8.1 mm | 14.8 mm | 2.0 mm |
| M10 | 10.2 mm | 18.1 mm | 2.2 mm |
| M12 | 12.2 mm | 21.1 mm | 2.5 mm |
| M16 | 16.2 mm | 27.4 mm | 3.5 mm |
- Automotive Industry: Securing chassis components, engine mounts, and suspension systems.
- Power Tools & Equipment: Essential for internal motor assemblies and vibrating machinery.
- Construction Equipment: Using High-Tension DIN 7980 washers in cranes, excavators, and steel framing.
- Electronics: Small M2 and M3 spring washers are used to protect PCBs from loose connections.
A: DIN 127 is the standard split spring washer for hex bolts. DIN 7980 has a smaller outer diameter and square ends, designed specifically to fit into the counterbores for Socket Head Cap Screws.
Q: Why use 65Mn steel for spring washers?
A: 65Mn (Manganese Steel) offers exceptional hardness and fatigue resistance after quenching, ensuring the washer maintains its spring force over thousands of vibration cycles.
