Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and reducing maintenance costs.
- Exceptional holding power provided by the Class 3A thread fit, ensuring a tight, secure, and vibration-resistant connection.
- Easy and secure installation with a 1/4" hex drive, allowing for high torque application without the risk of tool slippage.
- Deep, positive grip from the cup point tip, which bites into the shaft material to prevent component slippage and rotation.
- Enhanced durability and strength with a Rockwell B80 hardness, offering excellent resistance to wear and deformation under load.
- Reliable and standardized performance guaranteed by compliance with the ASME B18.3 specification for consistent quality.
- Safe for regulated industries as it is RoHS 3 and REACH compliant, meeting strict environmental and safety standards.
Professional Applications & Engineering Value
This 1/2"-13 UNC Class 3A stainless steel set screw is engineered to solve critical challenges in power transmission and assembly. The coarse UNC thread and Class 3A fit provide a robust, vibration-resistant connection that is essential for securing gears, pulleys, and collars on rotating shafts. The headless design and cup point create a flush finish while generating high clamping force, preventing axial movement in high-torque applications. Made from 18-8 Stainless Steel, it resists rust and corrosion in demanding environments like food processing, marine, and outdoor machinery, ensuring long-term reliability and reducing downtime for maintenance and replacements.
Specification Summary & Compliance
This set screw features a 1/2"-13 UNC coarse thread with a precision Class 3A fit for superior thread engagement. It is manufactured in accordance with the ASME B18.3 standard, ensuring dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in environmentally conscious and regulated industrial markets.
