• Lightweight and corrosion-resistant construction from high-quality aluminum, ideal for applications where weight and environmental factors are a concern
• Reliable and consistent threading ensured by the Class 2B thread fit, providing smooth engagement with mating components and reducing cross-threading risks
• Broad material compatibility for use in metal sheets from 0.027" to 0.150" thickness, offering versatile application across various industrial assemblies
• Quick and efficient installation with a standard 17/32" drill bit, streamlining the assembly process and reducing labor time
• Secure flange design with a 0.685" diameter distributes load effectively, preventing pull-through and enhancing joint integrity
• Compliance with stringent environmental standards including REACH and RoHS 3, ensuring safety and regulatory acceptance for global markets

Professional Applications & Engineering Value

This aluminum ribbed rivet nut is engineered to solve critical challenges in metal fabrication and assembly. The ribbed body bites securely into pre-drilled holes, providing exceptional resistance to rotational and pull-out forces, which is a common failure point in dynamic or high-vibration environments like automotive frames, electronic enclosures, and machinery. The 5/16"-18 UNC coarse thread and Class 2B fit ensure reliable, durable threads that withstand repeated disassembly without stripping. Made from aluminum, it offers an optimal balance of strength and lightweight properties, reducing overall assembly weight while resisting corrosion. The open end and right-hand thread design facilitate easy installation and compatibility with standard tools, making it a go-to solution for creating strong, threaded inserts in thin metal sheets where traditional welding or nuts are impractical.

Specification Summary & Compliance

This rivet nut adheres to UNC coarse thread standards with a Class 2B thread fit for consistent, precise threading. Key dimensions include a body diameter of 0.53", flange diameter of 0.685", and an installed length of 0.47", designed for material thicknesses from 0.027" to 0.150" using a 17/32" drill bit. The product is manufactured in compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) directives, ensuring it is free from hazardous substances and suitable for use in regulated industries.
