Corrosion Resistant DIN6797J Lock Washer Internal Teeth for Secure Fastening

Our DIN6797J Internal Tooth Lock Washer is a premium, high-performance fastener designed to provide exceptional anti-loosening security in demanding applications. Manufactured in strict compliance with the DIN6797J international standard (equivalent to the Chinese national standard GB/T 861.1-1987), this washer features a unique internal serrated design that bites into both the bearing surface and the bolt/nut head, creating powerful locking friction to prevent loosening under severe vibration and dynamic loads

• Superior Locking Mechanism: The precision-engineered internal teeth provide a strong bite, ensuring reliable locking force to maintain clamp load and prevent accidental backing off of fasteners

• High-Quality Material: Made from durable stainless steel (grades 304 or 316 available offering excellent corrosion resistance and longevity, even in harsh or humid environments.

• Precision Manufacturing: Produced with tight tolerances, ensuring consistent quality, perfect fit, and flat bearing surfaces for optimal performance.

• Standard Compliance: Fully conforms to DIN6797J specifications, guaranteeing interchangeability and reliability in global engineering projects.

• Available Sizes: Wide range of metric sizes available to fit bolts from M3 to M30, catering to diverse project requirements.

• Versatile Surface: Offered in plain (self-color) or zinc-plated finishes to suit different environmental and aesthetic needs
