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.
- Black-oxide coating on alloy steel provides enhanced corrosion resistance, extending service life in demanding industrial environments.
- Class 3A thread fit offers tighter tolerances for precise, secure fastening with minimal backlash in critical assemblies.
- 3/8" hex drive socket head allows for easy installation and high torque application with standard tools, improving assembly efficiency.
- Fully threaded design ensures consistent clamping force along the entire length, ideal for adjustable or deep-set applications.
- Rockwell C37 hardness provides excellent wear resistance, maintaining thread integrity through repeated use.
- Compliance with ASTM A574, RoHS 3, and REACH guarantees material consistency and environmental safety for global supply chain integration.
Professional Applications & Engineering Value
Engineered for high-strength fastening in machinery, automotive, and heavy equipment, this black-oxide alloy steel socket head cap screw addresses common industrial challenges like vibration loosening and corrosion. The 7/16"-14 UNC coarse threads with Class 3A fit deliver superior grip in soft materials or where quick assembly is critical, while the hex drive design enables access in confined spaces. Its 170,000 psi tensile strength and hardened material prevent stripping under dynamic loads, making it a reliable choice for structural applications requiring durability and precision.
Specification Summary & Compliance
This screw features a 1" length with fully threaded right-hand UNC coarse threads, adhering to Class 3A thread fit for high precision. It meets ASTM A574 specifications for alloy steel socket head cap screws, ensuring consistent mechanical properties. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it supports environmentally responsible manufacturing and usage in global markets.
