Professional Applications & Engineering Value
This split lock washer delivers critical vibration-resistant fastening solutions for industrial machinery, heavy equipment, and structural assemblies where constant motion and dynamic loads threaten joint integrity. The steel construction with Rockwell C38 hardness provides optimal spring tension that compensates for thermal expansion, material relaxation, and vibrational loosening. The standard split lock washer type design creates continuous opposing forces that prevent back-off in high-torque applications, making it ideal for construction equipment, manufacturing machinery, and transportation systems. With precise 1.534" ID and 2.419" OD dimensions for 1½" screw size compatibility, this washer ensures proper load distribution and seating in inch-system applications across various industrial sectors.
Specification Summary & Compliance
This split lock washer features dimensional specifications of 1.534" inner diameter, 2.419" outer diameter, and 0.375" thickness, designed specifically for 1½" screw size applications. Manufactured to ASME B18.21.1 standards for dimensional accuracy and performance requirements. The washer demonstrates full compliance with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) requirements (including 233 SVHC substances as of 01/17/2023), ensuring environmental safety and regulatory adherence for industrial distribution and use.
