Professional Applications & Engineering Value
This 18-8 stainless steel split lock washer delivers exceptional engineering value in demanding industrial environments where vibration-induced fastener failure is a critical concern. The split lock washer design creates continuous spring tension that compensates for thermal expansion, material relaxation, and vibration forces, maintaining secure fastening in heavy machinery, automotive assemblies, and structural applications. The corrosion-resistant properties of 18-8 stainless steel ensure reliable performance in harsh conditions, while the Rockwell C35 hardness provides the necessary strength to withstand repeated loading cycles without deformation. Engineered specifically for 3/4" screw applications, this washer solves the common industrial problem of fastener loosening while meeting rigorous quality standards.
Specification Summary & Compliance
This split lock washer features precise dimensional specifications including 0.766" inner diameter, 1.105" outer diameter, and 0.218" thickness, manufactured to ASME B18.21.1 standards for dimensional accuracy and performance reliability. The washer is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global manufacturing applications. Designed for use with 3/4" screws in inch measurement systems, this standard split lock washer type delivers consistent locking performance across industrial applications requiring vibration-resistant fastening solutions.
