- High Tensile Strength of 180,000 psi ensures reliable performance under heavy loads and vibration, reducing the risk of fastener failure.
- Precision Class 3A Thread Fit provides tighter tolerances for secure, vibration-resistant assemblies in critical applications.
- Non-Marring Brass Tip protects sensitive surfaces from scratches and damage during installation and use.
- Rockwell C39 Hardness offers excellent wear resistance and durability for long-term fastener integrity.
- Hex Socket Drive (5/32") allows for high-torque installation and removal with standard tools, improving assembly efficiency.
- Fully Threaded Design ensures consistent clamping force along the entire 5/8" length for uniform load distribution.
Professional Applications & Engineering Value
This 10-32 UNF Socket Head Cap Screw is engineered for precision assemblies where reliability and surface protection are paramount. The black-oxide alloy steel construction resists corrosion in humid or chemically exposed settings, while the fine thread spacing and Class 3A thread fit minimize loosening in high-vibration machinery, automotive, and aerospace applications. The integrated non-marring brass tip is ideal for electronics, fixtures, and finished products, preventing cosmetic damage without compromising the 180,000 psi tensile strength. Its fully threaded right-hand design ensures easy alignment and secure fastening in tight spaces, making it a versatile solution for OEMs and maintenance teams requiring consistent, high-performance industrial fasteners.
Specification Summary & Compliance
This screw adheres to ASME B18.3 specifications with a Class 3A thread fit for precise dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental safety. Manufactured from alloy steel per ASTM A574, it features a UNF fine thread with a 5/8" length and right-hand thread direction, suitable for inch-system applications requiring high strength and durability.
