Welcome to Anping County Boli Hardware Wiremesh Products Factory – your trusted manufacturer of high-quality fasteners since 1998. Our 304 Stainless Steel Double Coil Spring Washer DIN 127 M6-M30 is engineered to provide reliable anti-loosening performance for demanding industrial applications. With over two decades of experience and annual exports reaching US$5–10 million, we deliver precision components that meet international standards. This spring washer is designed to prevent bolt loosening caused by vibration, thermal expansion, or dynamic loads, ensuring long-term joint integrity.
Product Features and Technical Specifications:
- Material: Premium 304 stainless steel (AISI 304) – excellent corrosion resistance, suitable for outdoor, marine, and chemical environments.
- Standard: Compliant with DIN 127 – ensures dimensional accuracy and spring properties.
- Double Coil Design: Two coils provide enhanced spring force and better load distribution compared to single coil washers.
- Size Range: Available from M6 to M30, covering common bolt diameters for various applications.
- Anti-Loosening Function: The spring action exerts axial force, creating friction between the bolt head and nut surface, preventing self-loosening.
- Surface Finish: Natural stainless steel finish – no additional coating required, maintaining original corrosion resistance.
- Temperature Resistance: 304 stainless steel can withstand temperatures from -200°C to +800°C (depending on environment).
- Packaging Options: Customizable per customer request – bulk bags, small boxes, or poly bags with labels.
