Key Features & Benefits at a Glance
- Superior corrosion resistance with black-oxide coating, extending service life in demanding industrial environments.
- Exceptional holding power provided by the Class 3A thread fit, ensuring a secure, vibration-resistant connection.
- High-strength durability from Rockwell C45 hardened alloy steel, resisting wear and deformation under heavy loads.
- Secure and efficient installation with the 1/16" hex drive, allowing for high torque application in confined, headless designs.
- Enhanced grip and minimal surface damage from the cup tip design, ideal for precise positioning on shafts and collars.
- Reliable performance in high-vibration applications due to the coarse (UNC) thread spacing, which resists loosening.
- Broad industrial compatibility with right-hand thread direction, conforming to common assembly practices and tooling.
Professional Applications & Engineering Value
This black-oxide alloy steel set screw is engineered to solve critical challenges in machinery assembly and precision component fixing. The headless design with a hex drive is perfect for applications where space is limited, and a flush finish is required, such as in securing gears, pulleys, and knobs onto shafts. The cup tip concentrates force on a small area, providing excellent grip without causing significant damage to the shaft surface, which is vital for maintaining the integrity of rotating components. Made from hardened alloy steel and featuring a 6-32 UNC coarse thread, it delivers high resistance to vibrational loosening, making it a reliable heavy-duty fastener in automotive, aerospace, and industrial equipment where joint integrity is non-negotiable.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit for high precision and strength in unified inch series. It is manufactured in compliance with ASME B18.3 specifications, ensuring dimensional accuracy and performance reliability. The product is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for use in various global markets.
