- Exceptional holding power with the 90° cone point design that bites into materials for a secure, non-slip grip.
- High-strength and durability provided by alloy steel and Rockwell C45 hardness, resisting wear and deformation under heavy loads.
- Precise, reliable fastening ensured by Class 3A UNF fine threads, offering tighter tolerances and vibration resistance.
- Easy installation and removal with the 1/4" hex drive, allowing for high torque application in confined, headless designs.
- Broad industrial compliance meeting ASME B18.3, ASTM F912, RoHS 3, and REACH, ensuring safety and regulatory acceptance.
- Optimized for fine adjustments with right-hand fine threads, ideal for precise positioning in machinery and assemblies.
Professional Applications & Engineering Value
This black-oxide alloy steel set screw is engineered to address common industrial challenges like slippage, corrosion, and vibration loosening in high-stress applications. The 90° cone point and Class 3A UNF fine threads provide maximum grip and alignment in components such as gears, pulleys, and shafts, preventing movement under dynamic loads. Made from robust alloy steel with a Rockwell C45 hardness, it withstands repeated torque and environmental exposure, reducing maintenance needs. Its headless hex drive design allows for flush mounting in tight spaces, making it a reliable choice for industrial machinery, automotive systems, and precision equipment where durability and compliance with standards like ASME B18.3 are critical.
Specification Summary & Compliance
This set screw features precise Class 3A thread fit with 1/2"-20 UNF fine threads, ensuring tight tolerances and reliable performance. It complies with ASME B18.3 and ASTM F912 specifications for dimensional accuracy and manufacturing quality. Additionally, it is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety regulations for industrial use.
