Key Features & Benefits at a Glance
- Exceptional tensile strength (140,000 PSI) ensures reliable performance under high-stress conditions, reducing failure risks
- Zinc-plated alloy steel construction provides superior corrosion resistance for extended service life in harsh environments
- Class 3A thread fit delivers precise, vibration-resistant connections for critical assembly applications
- Low-profile socket head design allows installation in confined spaces while maintaining 1/4" hex drive compatibility
- Fully threaded shank enables maximum grip length and uniform load distribution across the entire fastener
- Rockwell C39 hardness rating maintains thread integrity and prevents stripping during repeated installations
- Coarse UNC threading facilitates quicker assembly and reduces cross-threading incidents in industrial settings
Professional Applications & Engineering Value
Engineered for demanding industrial applications, these socket head cap screws combine zinc-plated alloy steel construction with Class 3A UNC coarse threads to solve common assembly challenges. The low-profile socket head design provides clearance advantages in tight spaces while maintaining high torque capability through the 1/4" hex drive. The fully threaded configuration ensures maximum engagement in machinery, automotive components, and structural frameworks where vibration resistance is critical. With 140,000 PSI tensile strength and Rockwell C39 hardness, these fasteners withstand extreme mechanical stresses while the zinc plating protects against corrosion in manufacturing environments, reducing maintenance frequency and downtime.
Specification Summary & Compliance
This 1/2"-13 UNC socket head cap screw features Class 3A thread fit precision with coarse thread spacing for optimal engagement. Manufactured to ASTM A574 specifications, the fastener ensures consistent quality and performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring strict material compliance standards.
