Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
- Exceptional holding power ensured by the Class 3A thread fit, providing a tight, secure connection.
- High torque transmission via the hex drive design, allowing for easy and secure installation with standard tools.
- Enhanced durability from Rockwell B80 hardness, resisting wear and deformation under heavy loads.
- Reliable positioning with the cup tip, which minimizes surface damage and provides positive seating.
- Broad compatibility with the UNC coarse thread and right-hand direction, fitting common industrial components.
- Long-term safety and compliance by meeting ASME B18.3, RoHS 3, and REACH standards for quality and environmental safety.
Professional Applications & Engineering Value
This 3/8"-16 UNC Class 3A stainless steel set screw is engineered to address critical challenges in industrial assembly, such as component slippage and corrosion-induced failure. Its 18-8 stainless steel material offers excellent resistance to rust and chemicals, making it suitable for applications in machinery, automotive, and outdoor equipment where exposure to moisture is common. The headless design and hex drive allow for flush mounting and high-torque installation, preventing loosening in high-vibration environments. With a coarse thread spacing and cup tip, it ensures quick assembly and minimal damage to shafts or hubs, providing reliable, long-term performance in demanding settings like motor mounts and pulley systems.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including Class 3A thread fit for tight tolerances and UNC thread type with a 3/8"-16 size. It is manufactured in compliance with ASME B18.3 specifications and meets regulatory requirements such as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free from hazardous substances and safe for various industrial uses.
