Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress industrial applications, reducing the risk of fastener failure.
- Superior corrosion resistance from zinc plating extends service life in harsh environments, minimizing maintenance and replacement costs.
- Precise Class 3A thread fit provides tight, secure fastening with reduced risk of loosening under vibration or dynamic loads.
- High hardness (Rockwell C37) offers excellent wear resistance, maintaining thread integrity and drive engagement over repeated use.
- Coarse UNC threads enable quick and easy installation, saving time in assembly and disassembly processes.
- Fully threaded design allows for uniform clamping force along the entire length, enhancing joint stability.
- Compliance with ASTM A574 and environmental regulations ensures consistent quality and safe use in regulated industries.
Professional Applications & Engineering Value
Engineered for demanding environments, these zinc-plated alloy steel socket head cap screws deliver robust performance in heavy machinery, automotive assemblies, and construction equipment. The coarse 5/8"-11 UNC thread and Class 3A fit provide superior resistance to vibration loosening, a common issue in dynamic applications. With a 1/2" hex drive and standard socket head profile, they allow for high-torque installation without stripping, ensuring reliable fastening in tight spaces. The combination of 170,000 psi tensile strength and zinc plating addresses critical needs for durability and corrosion protection, making them ideal for outdoor or chemically exposed settings where failure is not an option.
Specification Summary & Compliance
This socket head cap screw features a Class 3A thread fit per UNC standards, ensuring precise dimensional accuracy for secure assembly. It is manufactured in compliance with ASTM A574 specifications, guaranteeing consistent mechanical properties and performance. The product is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting stringent environmental and safety regulations for use in global markets.
