Professional Applications & Engineering Value
Engineered for industrial fastening systems, this steel clipped washer solves critical assembly challenges. Its clipped design ensures positive locking against rotation, eliminating loosening under vibration in machinery and structural applications. The Rockwell B40 hardness provides excellent resistance to deformation under high bolt loads, maintaining clamping force integrity in heavy-duty equipment. The precise 0.531" ID guarantees perfect alignment with 1/2" screws, while the generous 1.75" OD distributes pressure effectively across softer materials. These inch system washers deliver reliable performance in construction, manufacturing, and maintenance operations where vibration resistance and dimensional accuracy are paramount.
