S-93031A163 1/4"-28 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and chemical exposure
• Reliable reverse-thread security through left-hand UNF fine threads, preventing loosening in rotating machinery applications
• Space-saving thin profile (5/32" height) enables use in confined assemblies without compromising strength
• Precise Class 2B thread fit ensures smooth engagement and consistent clamping force with mating components
• Optimized tool engagement with external hex drive design (7/16" width) for secure torque application
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for industrial safety requirements
• Fine thread advantage providing better vibration resistance and improved adjustment precision

Professional Applications & Engineering Value

This left hand thin hex nut delivers critical engineering solutions where standard fasteners fail. The 316 stainless steel composition provides exceptional corrosion resistance against chlorides and industrial chemicals, making it ideal for marine equipment, chemical processing plants, and food-grade applications. The UNF fine threads with Class 2B fit offer superior vibration resistance in machinery, while the left-hand thread direction prevents accidental loosening in counter-rotating systems. The thin profile allows installation in space-constrained assemblies where standard nuts cannot fit, maintaining structural integrity without adding bulk. These features combine to create a precision threaded nut that addresses common industrial challenges of corrosion, vibration, and spatial limitations.
