S-91228A118 1.062" ID Leveling Washers for I-Beams

Key Features & Benefits at a Glance

• Superior load distribution thanks to the tapered design, preventing surface damage and maintaining joint integrity under heavy loads
• Excellent corrosion resistance from the black-oxide iron finish, ideal for harsh industrial environments and outdoor applications
• High mechanical strength with Rockwell B62 hardness, ensuring long-term durability and resistance to deformation
• Precise compatibility with 1" screw sizes and 1.062" inner diameter, providing secure fastening and reducing installation errors
• Optimal stress reduction due to the tapered profile (0.562" to 0.219" thickness), minimizing the risk of loosening in dynamic applications
• Wide 2" outer width for enhanced surface contact, distributing pressure evenly and protecting sensitive materials
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries

Professional Applications & Engineering Value

This tapered washer is engineered to address critical challenges in industrial applications where uneven surfaces and high vibration can compromise fastener integrity. Made from black-oxide iron, it provides a robust barrier against moisture and chemicals, extending service life in demanding settings like construction, machinery assembly, and transportation equipment. The tapered geometry allows for precise alignment and compensates for angular discrepancies, reducing stress concentrations that lead to fatigue failure. With its Rockwell B62 hardness and inch-system dimensions, it ensures reliable performance in heavy-duty bolted connections, supporting structural stability while meeting stringent RoHS and REACH compliance for global supply chains.
