Key Features & Benefits at a Glance
- Superior Corrosion Resistance with black-oxide coating, extending service life in harsh industrial environments.
- High Tensile Strength (140,000 psi) ensures reliable performance under heavy loads and vibration.
- Precision Class 3A Thread Fit guarantees tight tolerances and secure fastening in critical assemblies.
- Ultra-Low Socket Head Profile allows installation in confined spaces without compromising drive engagement.
- Exceptional Hardness (Rockwell C32) provides excellent wear resistance and reduces thread stripping.
- Compliance with RoHS 3 & REACH ensures environmental safety and global regulatory acceptance.
- Fully Threaded 10-32 UNC Design offers consistent clamping force along the entire 1/4" length.
Professional Applications & Engineering Value
Engineered for precision machinery, automotive systems, and electronic enclosures, these black-oxide alloy steel socket head cap screws address critical challenges like space constraints and corrosion-induced failure. The ultra-low profile head paired with a 3/32" hex drive enables secure torque application in compact designs, while the 10-32 UNC fine threads with Class 3A fit prevent loosening under dynamic loads. The black-oxide surface treatment enhances corrosion resistance without adding significant thickness, making these screws ideal for applications demanding both dimensional accuracy and long-term durability in humid or chemically exposed environments.
Specification Summary & Compliance
This socket head cap screw adheres to inch system standards with a 10-32 UNC thread and Class 3A fit for precise engagement. Dimensional consistency is maintained through a length tolerance of -0.005" to 0.005". Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted substances are used. The combination of 140,000 psi tensile strength and Rockwell C32 hardness meets rigorous industrial demands for reliability and performance.
