S-90186A311 6-32 x 0.866" Rivet Nuts

Key Features & Benefits at a Glance

• Superior pull-out resistance with a bulbed body design that expands behind the material for a permanent, vibration-resistant hold in metal sheets.
• Enhanced corrosion protection from the zinc plating, extending the fastener's service life in demanding industrial environments.
• Reliable and fast installation with four folding sides that ensure even, high-strength clinching for a secure, flush finish.
• Broad material compatibility, designed for use in metal with a grip range from 0.188" to 0.375", offering versatile application solutions.
• Simplified sourcing and assembly with standard 6-32 UNC coarse threads and a right-hand thread direction for compatibility with common hardware.
• Optimized for high-volume production, featuring a 0.488" flange diameter that provides a larger bearing surface to distribute load and prevent pull-through.
• Compliance with global environmental standards, being RoHS 3 and REACH compliant for use in regulated markets and sustainable manufacturing.

Professional Applications & Engineering Value

This zinc-plated steel bulbed rivet nut is engineered to solve critical challenges in metal fabrication and assembly. Its bulbed body mechanically locks into place when installed, creating a robust threaded anchor that resists rotation and pull-out forces, even in thin-gauge materials. This is vital for applications in automotive frames, electronic enclosures, and machinery panels where vibration is a constant concern. The UNC coarse thread ensures rapid engagement and reduces cross-threading risks during high-speed assembly. With a specified 5/16" drill bit preparation, it streamlines the installation process, reducing labor time while delivering a high-strength, reliable fastening point that maintains integrity under dynamic loads.

Specification Summary & Compliance

This rivet nut features a body diameter of 0.335", flange diameter of 0.488", and a length of 0.866". It is manufactured to standard 6-32 UNC coarse thread specifications with a right-hand thread direction. The product is compliant with RoHS 3 (2015/863/EU) under exemption 6(a)-I and is REACH (EC 1907/2006) compliant, meeting stringent environmental and safety regulations for industrial components.
