Professional Applications & Engineering Value

These split lock washers deliver critical vibration-dampening performance for industrial machinery, automotive assemblies, and heavy equipment applications. The black-oxide steel construction provides essential corrosion resistance while maintaining the spring tension necessary for permanent fastener security. Engineered to ASME B18.21.1 standards, these washers address the fundamental challenge of joint relaxation under dynamic loads. The precise 0.26" internal diameter ensures perfect alignment with 1/4" fasteners, while the 0.363" outer diameter creates an optimal load-bearing surface. This combination of material properties and dimensional accuracy makes them ideal for maintenance-critical applications where vibration-induced failure is a primary concern, from conveyor systems to power transmission equipment.

Specification Summary & Compliance

Manufactured to exacting ASME B18.21.1 specifications for standard split lock washers, these components feature precise dimensional tolerances with 0.26" internal diameter, 0.363" outer diameter, and 0.078" thickness. The black-oxide steel construction achieves consistent Rockwell C38 hardness for reliable spring performance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance for industrial fastening applications.
