S-98514A041 3/8"-16 Hex Nuts

Key Features & Benefits at a Glance

• Enhanced corrosion resistance from Black-Oxide 18-8 Stainless Steel, ideal for humid or chemically aggressive environments.
• Space-saving thin profile with 7/32" height, allowing installation in tight spaces where standard nuts won't fit.
• Reliable coarse threading (UNC 3/8"-16) provides faster assembly and reduced cross-threading risk in industrial settings.
• Precise Class 2B thread fit ensures smooth engagement and consistent clamping force with mating components.
• Secure external hex drive offers excellent tool grip for high-torque applications without stripping.
• Full regulatory compliance with RoHS 3 and REACH, meeting strict international environmental and safety standards.
• Durable 18-8 stainless construction maintains strength and integrity under vibration and thermal cycling.

Professional Applications & Engineering Value

This 3/8"-16 UNC thin hex nut delivers critical performance where standard fasteners fail. The Black-Oxide 18-8 Stainless Steel construction resists oxidation and chemical degradation, making it suitable for outdoor equipment, marine hardware, and food processing machinery. Its thin profile solves clearance issues in compact assemblies like electrical enclosures or automotive subsystems, while the coarse UNC thread ensures rapid installation and disassembly in maintenance-heavy operations. The external hex drive allows for high torque application with common tools, preventing slippage and reducing assembly time. Engineered for industrial applications demanding reliable, corrosion-resistant coarse thread fastening, this nut maintains clamp load under dynamic stresses, reducing maintenance frequency and lifecycle costs.

Specification Summary & Compliance
