- Exceptional tip hardness (Rockwell C60) prevents deformation and maintains secure fastening under high rotational forces
- Precise Class 2A thread fit ensures smooth installation and reliable engagement with mating components
- Hex socket drive design provides maximum torque transmission and prevents tool slippage during tightening
- Ball tip configuration creates positive seating and reduces component surface damage during adjustment
- Heavy-duty alloy steel construction with Rockwell C32 body hardness delivers optimal strength-to-weight ratio
- Full regulatory compliance with RoHS 3 and REACH standards for global manufacturing applications
Professional Applications & Engineering Value
This black-oxide alloy steel set screw addresses critical challenges in precision assembly and machinery adjustment. The UNC coarse threading combined with Class 2A thread fit provides rapid installation while maintaining vibration resistance in dynamic applications. The Rockwell C60 hardened ball tip penetrates mating surfaces without excessive deformation, crucial for precision positioning in shafts, collars, and pulleys. The headless design with hex socket drive enables flush mounting in confined spaces while accommodating high torque requirements. Ideal for industrial machinery, automotive components, and manufacturing equipment where reliable set screw performance is essential for operational safety and precision alignment.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit tolerance and UNC coarse thread specification (3/8"-16). Features include 1" length, 3/16" hex drive, right-hand thread direction, and 0.275" ball tip diameter. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications and restricted substance management.
