Key Features & Benefits at a Glance

  • Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction, ideal for chemical, marine, and outdoor applications.
  • Reliable left-hand thread engagement prevents loosening under counter-clockwise rotational forces, ensuring secure fastening in specialized assemblies.
  • Precise Class 2B thread fit guarantees consistent mating with 10-24 UNC male threads, reducing the risk of cross-threading and assembly errors.
  • Robust UNC coarse threading provides faster installation and better performance in materials prone to galling or debris accumulation.
  • Standard external hex drive design allows for easy installation and removal with common wrenches, improving maintenance efficiency.
  • Compliance with RoHS 3 and REACH regulations ensures environmental safety and material transparency for global industrial supply chains.
  • Durable 5/16" width and 5/32" height profile offers a balanced strength-to-size ratio for space-constrained applications without compromising load capacity.

Professional Applications & Engineering Value

This 10-24 UNC left hand hex nut in 316 stainless steel is engineered to address critical challenges in industrial settings where reverse-thread mechanisms are essential. Its coarse thread design and Class 2B fit ensure rapid, secure assembly on rotating equipment, conveyor systems, and machinery subject to vibrational stress. The left-hand thread direction is particularly valuable in applications where standard right-hand threads may unintentionally loosen, such as in certain motor shafts or mixer assemblies. Made from 316 stainless steel, it provides exceptional resistance to chlorides, acids, and extreme temperatures, making it suitable for chemical processing, marine hardware, and food-grade environments. The external hex drive simplifies maintenance, reducing downtime in production lines and ensuring long-term reliability in corrosive or high-moisture conditions.

Specification Summary & Compliance

This hex nut adheres to UNC 10-24 coarse thread specifications with a Class 2B thread fit for consistent dimensional accuracy and compatibility. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring the absence of restricted hazardous substances. Manufacturing follows standard inch system dimensions: 5/16" width across flats and 5/32" height, suitable for use with common external hex drive tools in industrial and construction applications.
