Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and extended service life.
- Exceptional holding power and thread engagement provided by the UNC coarse threading and precise Class 3A thread fit, minimizing the risk of loosening under vibration.
- High mechanical strength and durability ensured by a Rockwell B80 hardness, offering reliable performance in demanding applications.
- Secure and flush installation with its headless design and hex drive, allowing for a clean finish and preventing snagging.
- Effective torque transmission via the 3/16" hex drive, facilitating easy installation and removal with standard tools.
- Enhanced grip and minimal surface damage from the cup tip, which concentrates force for a secure fit on shafts or components.
- Full compliance with industry standards including ASME B18.3, RoHS 3, and REACH, ensuring safety and environmental responsibility.
Professional Applications & Engineering Value
This 316 stainless steel set screw is engineered to address critical challenges in industrial settings, such as component slippage and corrosion-induced failure. Its UNC coarse thread and Class 3A fit deliver maximum engagement and vibration resistance, making it ideal for securing collars, gears, and pulleys on rotating shafts in machinery, automotive, and marine applications. The headless hex drive design allows for a flush mount, reducing protrusion risks in compact assemblies. Combined with corrosion-resistant 316 stainless steel and a cup tip for concentrated clamping force, it ensures long-term reliability in humid or chemically aggressive environments, preventing costly downtime and maintenance.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards with a Class 3A thread fit for tight tolerances and superior thread engagement. It conforms to ASME B18.3 specifications for set screws and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety requirements for industrial use.
