Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure.
- Superior corrosion resistance provided by the zinc-flake coating, extending service life in harsh industrial environments.
- Precise Class 3A thread fit guarantees secure, vibration-resistant assemblies with minimal risk of loosening.
- High hardness rating (Rockwell C37) enhances wear resistance and maintains thread integrity through repeated use.
- Partially threaded design allows for optimal clamping force and easier alignment in varied applications.
- Hex socket drive (5/32") enables high-torque installation and removal in confined spaces.
- Compliance with ASME B18.3 and ASTM A574 ensures consistent quality and interchangeability for professional use.
Professional Applications & Engineering Value
This 10-24 UNC Socket Head Cap Screw is engineered from zinc-flake-coated alloy steel to address critical industrial challenges, including vibration-induced loosening and environmental corrosion. The coarse thread spacing and Class 3A thread fit provide superior holding power in high-vibration machinery, automotive assemblies, and heavy equipment. Its partially threaded configuration ensures precise clamping without compromising structural integrity, making it ideal for applications requiring reliable fastening in tight spaces. With a 2 1/4" length and hex drive, it simplifies installation in complex assemblies, reducing downtime and maintenance costs.
Specification Summary & Compliance
This screw features a 10-24 UNC coarse thread with Class 3A precision tolerance and a minimum thread length of 7/8". It is manufactured in accordance with ASME B18.3 and ASTM A574 specifications, ensuring dimensional accuracy and mechanical reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting environmental and safety standards for global industrial use.
