Professional Applications & Engineering Value
This Black-Oxide Steel Split Lock Washer is engineered to address critical challenges in industrial fastening, such as vibration-induced loosening and corrosion. The split lock washer type creates continuous spring force against the nut and bearing surface, maintaining clamp load in high-vibration environments like automotive engines, heavy machinery, and electrical enclosures. Made from hardened steel with a Rockwell C38 rating, it offers excellent fatigue resistance and longevity, reducing maintenance frequency. The black-oxide surface treatment enhances corrosion protection, making it suitable for outdoor or humid conditions. Compatible with No. 10 screw sizes and designed to ASME B18.21.1 specifications, it ensures reliable performance in inch-system assemblies, from aerospace to construction, where precision and durability are paramount.
Specification Summary & Compliance
This washer features precise dimensions: 0.2" ID, 0.294" OD, and 0.047" thickness, conforming to ASME B18.21.1 standards for dimensional tolerances and performance in inch measurements. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and safe for various industrial applications.
