Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
- Enhanced vibration resistance and component protection from the durable green nylon 6/6 tip, preventing loosening and surface damage.
- High-strength performance with Rockwell B80 hardness, ensuring the set screw maintains its clamp load under stress.
- Precise, secure fastening thanks to the Class 3A thread fit and UNC coarse thread, providing excellent engagement and minimal backlash.
- Wide temperature tolerance with the nylon tip operating from -50° to 250°F, suitable for diverse industrial conditions.
- Easy installation and removal using a standard 5/64" hex key, facilitating efficient maintenance and assembly.
- Regulatory compliance and quality assurance by meeting ASME B18.3 standards and being RoHS 3/REACH compliant.
Professional Applications & Engineering Value
This 8-32 UNC set screw is engineered to address common industrial challenges such as component slippage, corrosion-induced failure, and vibration-induced loosening. The 18-8 stainless steel material offers excellent resistance to rust and chemicals, making it suitable for applications in machinery, automotive, and outdoor equipment. The hex headless design with a 5/64" hex drive allows for flush mounting in tight spaces, while the green nylon 6/6 tip provides a non-marring, secure grip that dampens vibrations and protects sensitive surfaces. Its Class 3A thread fit and coarse thread spacing ensure quick assembly and reliable holding power in right-hand thread applications, reducing maintenance downtime and improving operational safety.
Specification Summary & Compliance
This set screw features precise Class 3A thread fit per UNC standards, with a thread size of 8-32 and a length of 5/8". It complies with ASME B18.3 manufacturing specifications and is verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental safety and industry adherence.
