Professional Applications & Engineering Value
This split lock washer addresses critical vibration-induced loosening challenges in industrial applications where machinery and equipment experience constant dynamic forces. The zinc-plated steel construction provides dual benefits: the steel core delivers the necessary Rockwell C38 hardness for maintaining spring tension, while the zinc coating offers corrosion resistance in demanding environments. The standard split lock design creates continuous outward pressure against both the fastener head and bearing surface, effectively preventing rotational loosening in 3/8" screw assemblies. This engineering solution is particularly valuable for maintenance operations, production equipment, and automotive applications where vibration resistance directly impacts operational safety and reduces maintenance frequency.
Specification Summary & Compliance
This washer features precise dimensional specifications with 0.385" inner diameter, 0.68" outer diameter, and 0.094" thickness, engineered specifically for 3/8" screw applications. Manufactured to ASME B18.21.1 standards, it ensures consistent performance and interchangeability. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety requirements for industrial components.
