S-94450A336 3/4"-16 Hex Nuts

Key Features & Benefits at a Glance

• Left-hand thread design ensures secure fastening in applications requiring reverse-thread mechanisms to prevent loosening under counter-clockwise motion
• Corrosion-resistant 18-8 stainless steel construction provides excellent durability in harsh environments, reducing maintenance and replacement costs
• Thin profile (27/64" height) saves space and weight in compact assemblies without compromising strength
• Precision Class 2B thread fit guarantees smooth engagement and reliable performance with mating components
• UNF fine threading (3/4"-16) offers superior vibration resistance and improved load distribution compared to coarse threads
• External hex drive style allows for easy installation and removal with standard tools, enhancing assembly efficiency
• RoHS 3 and REACH compliance ensures environmental safety and regulatory adherence for global industrial applications

Professional Applications & Engineering Value

This 3/4"-16 UNF left-hand thin hex nut is engineered to address critical challenges in industrial settings where standard right-hand threads may loosen under specific rotational forces. The 18-8 stainless steel material delivers exceptional corrosion resistance, making it ideal for machinery, marine equipment, and chemical processing applications exposed to moisture and corrosive agents. Its thin profile design is particularly valuable in space-constrained assemblies, such as automotive components or precision instruments, where every millimeter counts. The UNF fine thread and Class 2B fit ensure tight, secure connections that resist vibration-induced failures, while the left-hand thread direction provides reliable performance in systems like rotating shafts or mixer blades that operate in reverse. This combination of features minimizes downtime and enhances operational safety in demanding B2B environments.

Specification Summary & Compliance

This hex nut adheres to UNF thread standards with a 3/4"-16 fine thread size and Class 2B thread fit for precise dimensional accuracy. The external hex drive and left-hand thread direction comply with industrial fastening specifications. It is manufactured from 18-8 stainless steel and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring it is free from hazardous substances and suitable for regulated applications.
