• Versatile installation range designed for material thicknesses from 0.03" to 0.09", accommodating various metal applications
• Enhanced pull-out resistance with 0.4" flange diameter providing wider load distribution and improved joint integrity
• Streamlined installation process compatible with standard 3/8" drill bits, reducing setup time and tooling requirements
• Environmental compliance assurance meeting REACH and RoHS 3 standards for safe industrial use and global market acceptance
• Durable steel construction with sleeve body design that maintains structural integrity under vibration and heavy loads

Professional Applications & Engineering Value

This 1/4"-28 UNF rivet nut delivers exceptional engineering value in metal fabrication and assembly operations. The tin-zinc plated steel construction provides superior corrosion protection compared to standard zinc plating, making it ideal for automotive, machinery, and outdoor equipment applications where environmental exposure is a concern. The fine thread spacing and Class 2B thread fit ensure precise mating with corresponding UNF bolts, eliminating play and maintaining clamping force in vibrating environments. The sleeve body design with 0.4" flange diameter distributes load effectively, preventing material deformation in thin sheet metals from 0.03" to 0.09" thickness. This combination of features solves common industrial challenges including thread stripping, corrosion-induced failure, and installation inconsistency in high-volume production settings.
