Key Features & Benefits at a Glance
- Exceptional holding power with a 90° cone point that bites into shafts and components to prevent rotational slippage.
- Superior thread precision with Class 3A fit ensures tight, secure fastening and vibration resistance in demanding applications.
- Enhanced durability and corrosion resistance provided by the black-oxide finish on the alloy steel material.
- High-strength construction with a Rockwell C45 hardness rating for reliable performance under heavy loads.
- Easy and secure installation using the 3/16" hex drive, allowing for high torque application in confined, headless designs.
- Optimized for fine-thread applications with the 3/8"-24 UNF thread offering improved adjustment and load distribution.
- Broad industrial compliance meeting ASME B18.3 and ASTM F912 standards for guaranteed quality and interoperability.
Professional Applications & Engineering Value
This black-oxide alloy steel set screw is engineered to solve critical challenges in power transmission and precision assembly. The headless design and hex drive allow for flush mounting in tight spaces, while the 90° cone point creates a permanent, high-friction lock on shafts, pulleys, and gears to prevent axial movement. The Class 3A UNF fine threads provide superior resistance to vibrational loosening, making it ideal for machinery, automotive, and aerospace applications where reliability is non-negotiable. Manufactured from high-strength alloy steel and treated to a Rockwell C45 hardness, it delivers long-term performance in high-stress environments, ensuring your assemblies remain secure and maintenance-free.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Class 3A thread fit for superior tolerance and a 3/8"-24 UNF fine thread. It is manufactured in compliance with ASME B18.3 and ASTM F912 specifications. The product is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety regulations for global industrial use.
