Key Features & Benefits at a Glance
- Exceptional tensile strength of 140,000 psi ensures reliable performance in high-stress industrial applications
- Corrosion-resistant black-oxide coating provides enhanced durability and longevity in challenging environments
- Precision Class 3A thread fit delivers superior engagement and vibration resistance for critical assemblies
- Low-profile socket head design allows installation in confined spaces while maintaining high torque capability
- Rockwell C39 hardness rating guarantees excellent wear resistance and dimensional stability under load
- Coarse UNC thread pattern enables faster installation and reduced cross-threading risks
- Full threading along the entire 1" length provides maximum adjustability and clamping force distribution
Professional Applications & Engineering Value
These black-oxide alloy steel socket head cap screws deliver critical engineering advantages for demanding applications where space constraints and high mechanical stresses coexist. The low-profile socket head design combined with the 5/32" hex drive enables secure fastening in compact assemblies while maintaining accessibility for maintenance. The Class 3A thread fit ensures precise engagement with mating components, significantly reducing the risk of vibration-induced loosening in machinery, automotive, and heavy equipment applications. The coarse 5/16"-18 UNC thread configuration provides rapid installation in production environments while the 140,000 psi tensile strength makes these fasteners ideal for structural connections, fixture plates, and high-pressure assemblies where failure is not an option.
Specification Summary & Compliance
Manufactured to exacting ASTM A574 specifications, these socket head cap screws feature precision Class 3A thread tolerances with coarse UNC thread form and right-hand thread direction. The fasteners maintain dimensional accuracy with 0.3125" thread diameter and 1" fully threaded length. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures they meet international standards for restricted substances, making them suitable for global industrial applications and export requirements.
