Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit ensuring tight, secure fastening in demanding applications.
- Enhanced durability and corrosion resistance from black-oxide alloy steel construction, extending service life in harsh environments.
- High strength and wear resistance due to Rockwell C45 hardness, preventing deformation under heavy loads.
- Easy installation and removal with 5/16" hex drive, allowing for efficient assembly and maintenance.
- Effective grip and minimal surface damage from the cup tip design, ideal for precise positioning on shafts or components.
- Reliable performance in coarse thread applications with 5/8"-11 UNC threads, providing quick assembly and strong vibration resistance.
- Compliance with industry standards including ASME B18.3, RoHS 3, and REACH, ensuring safety and environmental responsibility.
Professional Applications & Engineering Value
This 5/8"-11 UNC set screw is engineered to address common industrial challenges such as component slippage and vibration-induced loosening. Made from black-oxide alloy steel, it offers excellent corrosion protection and strength, making it suitable for heavy-duty machinery, automotive assemblies, and precision equipment. The Class 3A thread fit and coarse UNC thread design ensure a secure, tight hold in right-hand thread applications, reducing maintenance downtime. Its headless and cup tip configuration allows for flush mounting and minimal marring on surfaces, providing reliable performance in pulley systems, couplings, and other rotational components where space and precision are critical.
Specification Summary & Compliance
This set screw features a 5/8"-11 UNC coarse thread with Class 3A thread fit for high precision and strength. Dimensions include a 0.625" thread diameter, 1/2" length, and 5/16" hex drive. It meets ASME B18.3 specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and adherence to industrial standards.
