Professional Applications & Engineering Value

This fiberglass flange nut delivers exceptional performance in corrosive environments where traditional metal fasteners fail. The gray fiberglass construction provides inherent resistance to chemicals, moisture, and electrical conductivity, making it ideal for electrical enclosures, marine equipment, and chemical processing applications. The 1 1/32" flange diameter eliminates the need for separate washers, distributing clamp load over a wider area to prevent surface damage to connected materials. With UNC coarse threads and Class 2B thread fit, this nut ensures reliable engagement even in high-vibration settings, maintaining joint integrity while simplifying maintenance procedures. The external hex drive design allows for standard tool compatibility, streamlining installation across various industrial assembly lines.

Specification Summary & Compliance

This flange nut features precise 1/2"-13 UNC coarse threads with Class 2B thread fit per ASME B1.1 standards, ensuring consistent dimensional accuracy. The 1 1/32" flange diameter and 0.13" flange thickness provide optimal load distribution characteristics. Manufactured to meet RoHS 3 (2015/863/EU) compliance requirements, this fastener adheres to strict environmental regulations while maintaining the mechanical properties necessary for industrial fastening applications in the inch measurement system.
