Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit for precise, vibration-resistant fastening in demanding applications.
- Enhanced corrosion resistance from the black-oxide finish on alloy steel, extending service life in harsh industrial environments.
- High-strength durability with Rockwell C45 hardness, ensuring reliable performance under heavy loads and repeated use.
- Secure, deep engagement provided by the 90° cone point, which bites into materials to prevent slippage and maintain alignment.
- Easy installation and removal using the 1/8" hex drive, allowing for efficient maintenance with standard tools.
- Space-saving headless design ideal for confined spaces where protruding fasteners are not feasible.
- Wide compatibility with UNF fine threads (1/4"-28) for precise adjustments and strong connections in machinery and assemblies.
Professional Applications & Engineering Value
This 1/4"-28 UNF set screw is engineered to address common industrial challenges such as component slippage, misalignment, and corrosion in high-stress environments. Constructed from black-oxide alloy steel, it offers excellent resistance to wear and environmental factors, making it suitable for machinery, automotive, and aerospace applications where reliability is critical. The fine thread and Class 3A thread fit ensure tight tolerances and minimal backlash, while the 90° cone point provides superior grip on shafts and collars. Its headless design and hex drive facilitate easy installation in tight spaces, reducing assembly time and improving overall efficiency in production lines.
Specification Summary & Compliance
This set screw features a Class 3A thread fit for high precision, with UNF fine threads (1/4"-28) and a length of 3/4". It complies with ASME B18.3 and ASTM F912 standards, ensuring consistent quality and performance. Additionally, it is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety regulations for industrial use.
