Key Features & Benefits at a Glance

  • Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and marine applications
  • Reliable left-hand threading prevents unintentional loosening in counter-clockwise rotating systems and turnbuckle assemblies
  • Precise Class 2B thread fit ensures smooth engagement and consistent torque performance with mating components
  • Standard external hex drive provides easy installation and removal with common wrench tools
  • Coarse UNC threading offers faster assembly and better debris resistance in industrial settings
  • Full regulatory compliance with RoHS 3 and REACH standards for safe use in regulated industries
  • Durable standard hex profile maintains structural integrity under repeated tightening cycles

Professional Applications & Engineering Value

This 316 stainless steel left hand hex nut delivers exceptional performance in demanding applications where standard right-hand threads would compromise safety. The 3/8"-16 UNC coarse thread configuration provides superior vibration resistance in machinery, conveyor systems, and turnbuckle assemblies where reverse rotation occurs. The external hex drive design ensures compatibility with standard tools while the Class 2B thread fit guarantees precise mating with corresponding fasteners. Engineered for marine, chemical processing, and outdoor infrastructure applications, this nut's corrosion-resistant properties significantly extend service life in high-moisture and corrosive environments, reducing maintenance frequency and replacement costs.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2B thread fit tolerance for reliable performance. Features 3/8"-16 UNC left-hand coarse threading with standard 9/16" width and 5/16" height dimensions. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial compliance. The 316 stainless steel construction meets industry standards for corrosion resistance and mechanical durability in inch system applications.
