• Versatile coarse threading (5/8"-11 UNC) that handles debris better and installs faster in demanding environments

Professional Applications & Engineering Value

This Grade 8 steel flange nut delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The integrated 1 9/32" flange distributes clamping force over a wider area, preventing joint fatigue and surface damage in heavy machinery, structural steel connections, and automotive assemblies. The UNC coarse thread profile combined with Class 2B thread fit ensures reliable performance in high-vibration environments while accommodating minor misalignments. Manufactured from high-strength steel with external hex drive, this fastener withstands extreme torque requirements in construction, manufacturing, and transportation equipment where failure is not an option.

Specification Summary & Compliance
