Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit for reliable, vibration-resistant fastening in demanding applications.
- Enhanced durability and corrosion resistance provided by the black-oxide finish on the alloy steel material.
- High-strength performance backed by a Rockwell C45 hardness rating, ensuring long-term integrity under load.
- Easy and secure installation with the 1/4" hex drive, allowing for high torque application without slipping.
- Optimal engagement in coarse-threaded components due to the 1/2"-13 UNC coarse thread spacing.
- Space-saving headless design for applications where a flush or low-profile finish is required.
- Guaranteed compliance and reliability meeting ASME B18.3 specifications, RoHS 3, and REACH environmental standards.
Professional Applications & Engineering Value
This 1/2"-13 UNC set screw is engineered to address critical challenges in industrial assembly and machinery. The black-oxide alloy steel construction offers excellent resistance to rust and wear, extending service life in harsh environments. Its Class 3A thread fit and coarse thread spacing ensure a tight, secure hold, minimizing the risk of loosening due to vibration—a common issue in heavy-duty equipment. The headless design with a flat tip provides a flush mounting solution, ideal for securing collars, gears, and pulleys on shafts without protruding parts. The 1/4" hex drive allows for efficient installation with standard tools, reducing assembly time while maintaining high clamping force. Compliant with ASME B18.3, this set screw delivers consistent performance for OEM and MRO applications in automotive, aerospace, and manufacturing sectors.
Specification Summary & Compliance
This set screw features a 1/2"-13 UNC thread with Class 3A fit for precise dimensional accuracy and superior thread engagement. It is manufactured in accordance with ASME B18.3 specifications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material quality for global industrial use.
