- Environmental compliance meeting RoHS 3 and REACH standards for global industrial use
Professional Applications & Engineering Value
This M16 wedge lock washer delivers critical vibration-resistant performance in demanding industrial settings where fastener loosening can compromise safety and operational integrity. The Black-Oxide 316 Stainless Steel construction provides exceptional corrosion resistance in chemical processing, marine, and outdoor applications, while the top and bottom serration design creates positive mechanical locking action that prevents rotational slip. The case hardened treatment to Rockwell C46 ensures the serrations maintain their bite through repeated loading cycles, making these metric washers ideal for heavy machinery, structural assemblies, and transportation equipment where reliable locking under vibration is paramount.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 0.67" internal diameter, 1.21" outer diameter, and 0.110-0.130" thickness range for consistent M16 screw compatibility. The wedge lock washer features case hardening to Rockwell C46 hardness and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring strict material compliance and reliable locking performance.
