Key Features & Benefits at a Glance
- Superior corrosion resistance with black-oxide coating, extending service life in demanding industrial environments
- Precise Class 3A thread fit ensures vibration-resistant, secure fastening with minimal backlash in critical assemblies
- 90° cone point design creates deep penetration and maximum holding power against rotational forces
- Rockwell C45 hardness provides excellent wear resistance and maintains thread integrity under heavy loads
- 1/4" hex drive compatibility allows high-torque installation with standard industrial tools
- Headless construction enables flush mounting in space-constrained applications without protrusion
- Fine thread spacing (UNF) offers better tension distribution and improved adjustment precision
Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional performance in industrial machinery, automotive components, and precision equipment where vibration resistance and permanent positioning are critical. The 90° cone point aggressively bites into shaft materials, preventing slippage in high-torque applications, while the Class 3A UNF threads maintain precise tolerances for repeated assembly cycles. The black-oxide surface treatment provides reliable corrosion protection without dimensional changes, making these headless set screws ideal for permanent installations in harsh operating conditions. Engineered to withstand heavy rotational forces, they ensure component alignment remains secure throughout equipment service life.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 specifications with ASTM F912 material standards, this set screw features 1/2"-20 UNF Class 3A fine threads with precise dimensional control. The 2" length and 0.5" thread diameter provide optimal engagement for various shaft sizes. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
