S-97217A362 5/16"-18 x 1.375" Rivet Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc yellow-chromate plating, extending service life in demanding industrial environments
• Enhanced pull-out resistance due to the bulbed body design, providing superior holding power in plastic applications
• Reliable and fast installation with coarse UNC threads and Class 2B fit, ensuring smooth engagement and reducing assembly time
• Versatile material compatibility designed specifically for plastic substrates with a thickness range of 0.280" to 0.500"
• Secure flange design with 0.77" diameter, distributing load effectively and preventing material damage
• Optimized for efficiency with four folding sides, creating a strong, permanent blind thread in pre-drilled 1/2" holes
• Compliance assurance meeting REACH and RoHS 3 standards, ensuring safe use in regulated industries

Professional Applications & Engineering Value

This 5/16"-18 UNC rivet nut delivers exceptional engineering value by solving critical fastening challenges in plastic assemblies. The zinc yellow-chromate-plated steel construction provides superior corrosion protection where moisture or chemicals are present, while the bulbed body design expands behind the material to create a permanent, vibration-resistant installation that won't pull through thin plastic substrates. The coarse thread spacing and Class 2B thread fit ensure reliable engagement with mating components, reducing cross-threading risks during high-volume production. With its specialized design for 0.280" to 0.500" material thickness, this rivet nut eliminates the need for additional reinforcement in plastic enclosures, electronic housings, and automotive trim applications, providing strong threaded points where welding or through-bolting isn't feasible.

Specification Summary & Compliance

This heavy-duty rivet nut maintains Class 2B thread fit per UNC standards, ensuring consistent dimensional accuracy and reliable mating with Class 2A external threads. The product features a 0.5" body diameter, 0.77" flange diameter, and 1.375" installed length with four folding sides for uniform expansion. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) directives, confirming environmental compliance for industrial applications requiring hazardous substance restrictions.
