Professional Applications & Engineering Value
These zinc-plated steel clipped washers deliver critical engineering solutions where standard round washers fail. The clipped design with 0.63" width provides positive locking against rotation in high-vibration applications common in automotive, machinery, and electrical panel assemblies. The zinc plating creates a sacrificial barrier that significantly extends service life in corrosive environments, while the Rockwell B40 hardness ensures consistent performance under repeated torque cycles. Engineered specifically for 1/4" screw systems, these industrial washers prevent loosening in dynamic load conditions, making them ideal for manufacturing equipment, transportation components, and heavy-duty fastening applications where reliability is paramount.
Specification Summary & Compliance
Manufactured to precise inch system dimensions with 0.281" inner diameter and 0.75" outer diameter, these clipped washers maintain consistent thickness between 0.056-0.071". The construction meets industrial fastener standards with Rockwell B40 hardness certification and full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe integration into global supply chains and manufacturing processes.
