Professional Applications & Engineering Value

This 18-8 stainless steel flange nut delivers critical engineering solutions for industrial leveling and mounting applications. The integrated 3/4" flange with 0.09" thickness provides superior load distribution, preventing surface damage and maintaining structural integrity under heavy loads. The UNC coarse thread configuration (5/16"-18) ensures rapid installation while resisting vibration-induced loosening in machinery, conveyor systems, and manufacturing equipment. Manufactured from corrosion-resistant stainless steel, this leveling flange nut maintains performance in humid, chemical, or outdoor environments where ordinary fasteners would degrade. The external hex drive accommodates standard tools for precise adjustment and secure fastening in space-constrained industrial applications.

Specification Summary & Compliance

This heavy-duty flange nut features precise Class 2B thread fit according to UNC standards with dimensions of 9/16" width and 17/32" height. The product complies with RoHS 3 (2015/863/EU) regulations with exemption 6(a) for lead as an alloying element in steel. Manufacturing adheres to standard industrial specifications for inch-system fasteners, ensuring compatibility with existing equipment and replacement applications across various industrial sectors.
