• Simplified inventory with inch system measurement compatible with standard industrial equipment

Professional Applications & Engineering Value

This tapered washer delivers critical engineering solutions where uneven surfaces and variable load conditions challenge conventional fasteners. The precisely engineered tapered design (0.406" to 0.156" thickness gradient) compensates for surface irregularities, eliminating point loading that causes material fatigue. Manufactured from iron with Rockwell B62 hardness, it maintains structural integrity under extreme pressure while the 1.5" width provides substantial bearing surface. Ideal for heavy machinery assembly, structural steel connections, and industrial equipment maintenance, this 5/8" screw compatible washer ensures uniform force distribution across bolted joints, preventing loosening and reducing maintenance frequency in demanding applications.

Specification Summary & Compliance

This inch-system tapered washer features precision dimensions: 0.688" ID, 1.5" width, with thickness tapering from 0.406" to 0.156". Engineered for 5/8" screw applications with Rockwell B62 hardness iron construction. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted industrial use across global markets.
