Every industrial application presents unique fastener locking challenges, and SUNZO delivers bespoke solutions with our Custom Serrated Safety Washers—engineered to DIN9250 standards while adapting to your specific requirements.
While our standard DIN9250 series covers M1.6 to M36, we specialize in extending these parameters to create non-standard solutions tailored for extreme environments and specialized machinery.
- Custom Dimensions: From micro-sized M1.0 to heavy-duty M50+
- Material Selection: 304/316 stainless steel for corrosion resistance, high-carbon steel for extreme load-bearing, or titanium alloys for aerospace-grade applications
- Gear Profile Refinement: Adjustable tooth angles of 45°-60°, variable tooth density, and specialized serration patterns
Each custom washer retains the core DIN9250 advantage: a precision gear surface that merges friction-generated clamping force with mechanical interlock, effectively neutralizing vibration-induced loosening in applications ranging from precision medical devices to offshore drilling equipment.
All custom solutions adhere to DIN 9250 specifications and undergo rigorous quality testing, including:
- Salt spray corrosion resistance (up to 1,000 hours for stainless steel variants)
- Hardness verification (HRC 43-45 for carbon steel options)
Whether you require washers for high-temperature automotive engines, sterile pharmaceutical machinery, or subsea oil rig components, our technical sales engineers provide end-to-end support—from material selection guidance to installation recommendations.
Transform your unique fastening challenges into engineered solutions that deliver uncompromising security and reliability.
