Key Features & Benefits at a Glance
- Exceptional tensile strength of 140,000 psi ensures reliable performance in demanding applications, reducing the risk of fastener failure.
- Superior thread precision with Class 3A fit provides excellent engagement and vibration resistance, minimizing loosening in dynamic environments.
- Corrosion-resistant black-oxide finish on alloy steel enhances durability and longevity, even in harsh industrial conditions.
- Low-profile socket head design offers a compact installation footprint, ideal for applications with limited clearance.
- High hardness rating of Rockwell C39 ensures excellent wear resistance and maintains thread integrity over repeated use.
- Fully threaded coarse UNC design allows for faster installation and stronger holding power in a wide range of materials.
- Standard-compliant manufacturing meeting ASTM A574 ensures consistent quality and reliability for professional use.
Professional Applications & Engineering Value
These low profile socket head cap screws are engineered from black-oxide alloy steel to address critical challenges in heavy machinery, automotive assembly, and precision equipment. The combination of 140,000 psi tensile strength and Class 3A thread fit provides superior clamp load and vibration resistance, preventing joint failure in high-stress environments. The coarse UNC threads facilitate quick assembly while maintaining strong grip in softer materials or where rapid disassembly isn't required. The low-profile head with 1/4" hex drive is particularly valuable in confined spaces where standard socket heads would protrude excessively. This makes them ideal for mounting brackets, machine frames, and structural components where reliability and space optimization are paramount.
Specification Summary & Compliance
This socket head cap screw features precision 1/2"-13 UNC coarse threads with Class 3A thread fit for tight tolerance applications. Manufactured to ASTM A574 specification for high-strength alloy steel fasteners. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industries.
