Professional Applications & Engineering Value
This Black-Oxide Iron tapered washer delivers critical engineering solutions for industrial applications where vibration resistance and load distribution are paramount. The tapered configuration compensates for surface irregularities and prevents fastener loosening in heavy machinery, structural assemblies, and automotive systems. Manufactured from Rockwell B62 hardness iron, it maintains structural integrity under repeated stress cycles while the black-oxide surface treatment provides corrosion protection in demanding environments. The precise 0.688" ID ensures perfect alignment with 5/8" fasteners, making it ideal for inch-system applications requiring reliable performance in construction, manufacturing, and equipment maintenance where consistent clamping force is essential for operational safety and longevity.
Specification Summary & Compliance
This tapered washer features precision inch-system dimensions including 0.688" inner diameter, 1.5" width, and tapered thickness from 0.406" to 0.156". Manufactured from Black-Oxide Iron with Rockwell B62 hardness for consistent performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring regulatory adherence for industrial applications worldwide.
