Professional Applications & Engineering Value
These zinc-plated steel split lock washers are engineered to solve critical vibration-induced loosening problems in industrial assemblies. The split lock washer design creates continuous spring tension that maintains clamping force even under severe vibration conditions, making them ideal for machinery, automotive, and electrical equipment applications. The Rockwell C38 hardness ensures the washer maintains its spring characteristics without deformation, while the zinc plating provides essential corrosion protection for extended service life. Perfectly sized for No. 5 screws with precise 0.133" ID and 0.236" OD dimensions, these standard lock washers deliver reliable performance in inch-system applications where vibration resistance is paramount.
Specification Summary & Compliance
This split lock washer features dimensional specifications of 0.133" inner diameter, 0.236" outer diameter, and 0.031" thickness, manufactured to ASME B18.21.1 standards for dimensional accuracy and performance. The product maintains compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and suitability for global industrial applications. Manufactured from zinc-plated steel with Rockwell C38 hardness, these washers provide consistent locking performance for No. 5 screw applications in inch measurement systems.
