The Stainless Steel M8 Spring Washer is a specialized vibration-resistant fastening solution engineered to maintain consistent clamp load in dynamic machinery assemblies. Manufactured to exacting DIN 127 standards, its unique split design creates a continuous spring force that counteracts bolt loosening caused by vibration, thermal expansion, or mechanical shock in industrial environments .
Parameter | Value |
Material | 304/316 Stainless Steel (A2-70/A4-80 for high tensile performance) |
Size | M8 (nominal diameter, compatible with M8 threaded fasteners) |
Inner Diameter | 8.1mm (with chamfered edges to prevent thread damage) |
Outer Diameter | 12.7mm (optimal for load distribution) |
Thickness | 2mm (standard for M8 bolt assemblies) |
Hardness | HV300-350 (after heat treatment for spring properties) |
• Double gripping power derived from its rectangular section design, which creates both radial and axial tension
• Superior corrosion resistance in humid, chemical, and outdoor environments, outperforming carbon steel alternatives
• Consistent tension retention under thermal cycling (operating temperature range: -40°C to 300°C)
• Compatible with standard M8 bolts and threaded components, requiring no special tools for installation
• Deburred edges to prevent damage to mating surfaces during assembly
Essential for heavy machinery in mining operations, automotive powertrain assemblies, industrial pump systems, and conveyor equipment in manufacturing facilities. It is particularly ideal for high-vibration environments like metalworking plants, construction machinery, and renewable energy installations (wind turbines, solar trackers) .
Q: What's the difference between 304 and 316 variants?
A: 316 grade contains molybdenum, offering enhanced chloride resistance for marine, coastal, or chemical processing applications, while 304 is suitable for general industrial use.
Q: Does this washer fit standard M8 bolts?
A: Yes, it's dimensionally compatible with all ISO 898-1 grade M8 fasteners, including partially threaded and fully threaded variants.
Q: Can it be reused after disassembly?
A: We recommend replacement after disassembly to maintain optimal tension; spring washers lose tension capacity after initial compression.
