Key Features & Benefits at a Glance
- Superior corrosion resistance with Black-Oxide finish, extending service life in demanding industrial environments.
- Exceptional thread precision with Class 3A fit for reliable, vibration-resistant fastening in critical assemblies.
- High-strength durability from Alloy Steel and Rockwell C45 hardness, resisting wear and deformation under load.
- Secure, deep-gripping engagement thanks to the 118° cone point design, preventing component slippage.
- Easy installation and removal with a 1/8" hex drive, compatible with standard tools for efficient maintenance.
- Optimized for fine-thread applications with UNF 1/4"-28 threads, providing enhanced clamping force in precision machinery.
- Space-saving headless design allowing flush mounting where clearance is limited.
Professional Applications & Engineering Value
This Black-Oxide Alloy Steel set screw is engineered to address common industrial challenges such as component misalignment and loosening under vibration. The Class 3A thread fit ensures tight tolerances, minimizing backlash in precision equipment like motor shafts, gears, and couplings. Its cone point with a 118° angle bites securely into materials, providing superior resistance to rotational forces. The hex drive allows for high-torque installation without stripping, making it ideal for assembly lines and maintenance operations. Compliant with ASME B18.3, it meets rigorous standards for dimensional consistency, ensuring reliable performance in automotive, aerospace, and heavy machinery applications where failure is not an option.
Specification Summary & Compliance
This set screw features a 1/4"-28 UNF fine thread with Class 3A fit for high precision, a length of 1/4", and a right-hand thread direction. It is manufactured in accordance with ASME B18.3 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safety and sustainability in industrial use.
