Professional Applications & Engineering Value
These black-oxide steel flat washers are engineered to address common industrial challenges, such as corrosion and load instability. The black-oxide surface treatment provides a protective layer that resists rust and oxidation, making them ideal for outdoor or humid conditions in construction, automotive, and heavy machinery applications. With precise dimensions—1.062" ID and 1.75" OD—they ensure a snug fit for 1" screw size fasteners, distributing loads evenly to prevent joint failure and reduce stress concentrations. Combined with Rockwell B80 hardness, these washers maintain integrity under high vibration and torque, offering long-term reliability for critical assemblies where safety and performance are paramount.
Specification Summary & Compliance
This flat washer meets standard inch system measurements with an inner diameter of 1.062", outer diameter of 1.75", and thickness ranging from 0.080" to 0.115". It is manufactured from black-oxide steel with a hardness of Rockwell B80, ensuring consistent performance. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to environmental and safety standards for industrial use.
