S-91944A470 Male and Female Leveling Washers

Key Features & Benefits at a Glance

• Superior misalignment compensation with a 2° maximum correction angle ensures proper load distribution and prevents premature fastener failure in uneven mounting surfaces.
• Excellent corrosion resistance from 18-8 Stainless Steel construction guarantees long-term reliability and performance in harsh or outdoor industrial environments.
• Enhanced mechanical strength with a Rockwell B80 hardness rating provides exceptional durability and resistance to deformation under heavy loads.
• Precision-engineered dimensions (1.125" OD, 0.531" ID) and consistent 1.5" spherical radius offer reliable, repeatable alignment for 1/2" fasteners in the inch system.
• Broad compatibility with replacement male washers simplifies assembly and maintenance, reducing inventory complexity and procurement time.
• Full regulatory compliance with RoHS 3 and REACH standards ensures product safety and unrestricted use in global markets.

Professional Applications & Engineering Value

This 1/2" spherical washer is engineered to solve critical alignment challenges in heavy-duty assemblies where surface irregularities can cause point loading, bolt bending, and joint failure. Manufactured from 18-8 Stainless Steel, it provides inherent corrosion resistance for demanding applications in construction, machinery, marine, and processing equipment. The precisely machined spherical surfaces and 2° correction angle allow the washer to pivot, ensuring full contact between the nut/bolt head and the workpiece. This distributes clamping forces evenly, significantly increasing joint integrity, reducing stress concentrations, and extending the service life of the entire assembly. Its Rockwell B80 hardness maintains dimensional stability under high vibration and load cycles, making it an essential component for reliable, long-term performance in critical connections.

Specification Summary & Compliance

This washer conforms to Inch System specifications with key dimensions including a Female/Male OD of 1.125", ID of 0.531", a spherical radius of 1.5", and a thickness between 0.298"-0.328". It is designed for use with 1/2" screws. The product is manufactured from 18-8 Stainless Steel and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets the latest environmental and safety standards for industrial components.
