S-91151A039 1.25" ID Leveling Washers for I-Beams

Key Features & Benefits at a Glance

• Superior load distribution with tapered design (0.625" to 0.281" thickness) to prevent joint loosening under vibration
• Exceptional durability from iron construction with Rockwell B62 hardness for long service life in demanding environments
• Precise compatibility with 1 1/8" screw sizes and 1.25" inner diameter for reliable fitment in inch-system applications
• Enhanced stability from 2.25" width providing increased surface contact area for secure fastening
• Environmental compliance with RoHS 3 and REACH standards ensuring safe use across regulated industries
• Reduced maintenance needs through corrosion-resistant iron material that withstands industrial conditions
• Versatile shimming capability allowing precise alignment correction in uneven mounting surfaces

Professional Applications & Engineering Value

This tapered washer delivers critical engineering solutions for industrial applications where surface irregularities compromise fastener integrity. The iron construction with Rockwell B62 hardness provides the necessary strength to maintain clamp load in high-vibration environments like heavy machinery, structural steel connections, and equipment mounting. The gradual thickness transition from 0.625" to 0.281" creates an effective tapered shim that compensates for angled surfaces up to 4 degrees, preventing bolt bending and distributing stress evenly across the 2.25" width. This industrial washer specifically engineered for 1 1/8" screw applications ensures reliable performance in construction, manufacturing, and maintenance operations where inch-system fasteners are standard.

Specification Summary & Compliance

This tapered washer features precise inch-system dimensions including 1.25" inner diameter, 2.25" width, and tapered thickness from 0.625" to 0.281". Manufactured from iron with Rockwell B62 hardness for consistent mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental standards for industrial components. Designed specifically for use with 1 1/8" screw sizes in inch-system applications.
