Key Features & Benefits at a Glance
- Exceptional tensile strength of 140,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from zinc plating extends service life in harsh industrial environments, minimizing maintenance needs.
- Precise Class 3A thread fit provides consistent engagement and vibration resistance, enhancing assembly integrity.
- Low-profile socket head design allows for easy installation in confined spaces with standard 1/4" hex tools.
- Fully threaded shank offers uniform clamping force along the entire length, ideal for adjustable or deep-set applications.
- High hardness (Rockwell C39) resists wear and deformation, ensuring long-term durability under repetitive loads.
- Compliance with ASTM A574, RoHS 3, and REACH guarantees material quality and environmental safety for global supply chains.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, this 1/2"-13 UNC socket head cap screw combines zinc-plated alloy steel construction with a coarse thread design to tackle common challenges like vibration loosening and corrosion. The low-profile head and hex drive facilitate quick installation in tight spaces, while the fully threaded rod ensures even stress distribution in heavy machinery, automotive assemblies, and structural frameworks. Its high tensile strength and hardness make it suitable for applications requiring reliable fastening under dynamic loads, reducing downtime and maintenance costs.
Specification Summary & Compliance
This screw features a 1/2"-13 UNC coarse thread with Class 3A fit for precise tolerance, manufactured per ASTM A574 specifications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards. Dimensions include a 1-1/2" length, 3/4" head diameter, and 1/4" drive size for consistent performance.
