Professional Applications & Engineering Value
These split lock washers provide critical vibration-dampening solutions for industrial machinery, automotive assemblies, and heavy equipment where constant motion and stress threaten fastener integrity. The zinc-plated steel construction combats corrosion in demanding environments, while the Rockwell C38 hardness maintains spring force under repeated loading cycles. Engineered specifically for 3/8" screw applications, these washers create reliable locking force through their split design that digs into both bearing surfaces, preventing rotational loosening in critical assemblies. The standard split lock washer type ensures compatibility with existing industrial specifications while delivering immediate spring action upon installation.
Specification Summary & Compliance
This split lock washer features precise dimensional specifications with 0.397" inner diameter, 0.688" outer diameter, and 0.094" thickness, engineered for optimal performance with 3/8" screws. Manufactured in compliance with ASME B18.21.1 standards for dimensional accuracy and mechanical properties. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations regarding chemical substances, ensuring environmental responsibility and workplace safety.
