S-95140A135 7/16"-14 Hex Nuts

Key Features & Benefits at a Glance

• Exceptional strength and reliability with Grade 5 steel construction, ideal for heavy-duty industrial applications
• Secure left-hand threading prevents loosening under counter-clockwise rotational forces in specialized machinery
• Precise Class 2B thread fit ensures smooth assembly and consistent clamping force with mating components
• Coarse UNC thread profile provides rapid installation and superior resistance to vibration and cross-threading
• Standard external hex design offers compatibility with common wrenches for easy maintenance and installation
• Full regulatory compliance with RoHS 3 and REACH standards for safe use in regulated environments
• Durable inch-sized construction (11/16" width, 3/8" height) delivers robust performance in demanding conditions

Professional Applications & Engineering Value

This Grade 5 steel hex nut with left-hand UNC coarse threads addresses critical engineering challenges in applications where reverse rotation is prevalent. The 7/16"-14 thread size and Class 2B fit provide optimal engagement with mating bolts, reducing the risk of mechanical failure in high-vibration environments like rotating machinery, conveyor systems, and automotive assemblies. The external hex drive style ensures straightforward installation and removal using standard tools, while the heavy-duty steel construction maintains integrity under significant tensile and shear stresses. These left hand threaded nuts are particularly valuable in equipment where right-hand threads would naturally loosen during operation, delivering enhanced safety and reduced maintenance requirements.

Specification Summary & Compliance

This hex nut features 7/16"-14 UNC coarse threads with Class 2B thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy and interchangeability. The standard hex nut profile measures 11/16" across flats and 3/8" in height. Manufacturing complies with Grade 5 strength requirements for consistent mechanical properties. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting the latest environmental and substance restriction regulations for industrial fasteners.
