Professional Applications & Engineering Value
These split lock washers are engineered to solve critical vibration-induced loosening problems in industrial assemblies. The zinc-plated steel construction provides dual benefits: the steel core delivers the necessary spring force to maintain bolt tension, while the zinc coating protects against corrosion in demanding environments. The standard split lock design creates continuous upward pressure against the fastener head or nut, effectively resisting rotational forces caused by machinery vibration, thermal cycling, and dynamic loads. Particularly valuable for No. 6 screw applications in electrical enclosures, automotive components, and machinery assemblies, these washers maintain joint integrity where reliability is paramount. The precise 0.148" inner diameter ensures proper seating without binding, while the 0.25" outer diameter provides optimal bearing surface for effective load distribution.
Specification Summary & Compliance
This split lock washer features precise dimensional specifications including 0.148" inner diameter, 0.25" outer diameter, and 0.031" thickness, engineered specifically for No. 6 screw size applications. Manufactured to ASME B18.21.1 standards for dimensional accuracy and performance requirements. The Rockwell C38 hardness ensures proper spring characteristics and locking functionality. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility and global market accessibility.
