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 from the black-oxide finish extends service life in harsh industrial environments, minimizing maintenance needs.
- Precision Class 3A thread fit guarantees secure, vibration-resistant connections for critical assemblies requiring exact tolerances.
- Extra fine UNEF threading provides enhanced grip and load distribution in thin materials or fine-pitch applications.
- High hardness (Rockwell C37) offers excellent wear resistance, maintaining thread integrity through repeated use.
- Hex socket drive design allows for easy installation in confined spaces with standard tools, improving assembly efficiency.
- Full threading along the 3/4" length enables flexible positioning and uniform clamping force across the entire fastener.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, this black-oxide alloy steel socket head cap screw combines high tensile strength and corrosion resistance to address common challenges like vibration loosening and environmental degradation. The 1/4"-32 UNEF extra fine thread with Class 3A precision ensures tight, reliable fits in applications such as precision machinery, aerospace components, and automotive systems where fine adjustments and minimal clearance are critical. Its fully threaded design and hex drive facilitate quick, secure installations even in hard-to-reach areas, reducing assembly time while maintaining consistent performance under dynamic loads.
Specification Summary & Compliance
This socket head cap screw features a Class 3A thread fit with UNEF extra fine threading for superior accuracy. It meets ASTM A574 specifications for high-strength alloy steel fasteners and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability in global supply chains.
