Key Features & Benefits at a Glance
- Exceptional tensile strength of 120,000 psi provides reliable performance in high-stress applications, reducing the risk of fastener failure.
- Zinc-plated alloy steel construction offers superior corrosion resistance, extending service life in demanding industrial environments.
- Class 3A thread fit ensures precise, tight engagement for secure fastening and vibration resistance.
- Fully threaded design maximizes holding power and allows for adjustable positioning along the entire length.
- Hex drive (5/64") and rounded button head enable easy installation with standard tools while providing a low-profile, finished appearance.
- UNC coarse thread facilitates quick assembly and reduces cross-threading risks in various materials.
- Compliance with ASME B18.3 and ASTM F835 guarantees consistent quality and interoperability with standardized components.
Professional Applications & Engineering Value
Engineered for industrial reliability, these zinc-plated alloy steel screws with 6-32 UNC coarse threads address critical fastening challenges in machinery, electronics, and heavy-duty assemblies. The rounded button head and hex drive design streamline installation in confined spaces, while the Class 3A thread fit minimizes loosening under dynamic loads. With a Rockwell C39 hardness and robust 120,000 psi tensile strength, they prevent stripping and withstand high torque, making them ideal for applications requiring repeated disassembly. The fully threaded configuration ensures uniform stress distribution, enhancing joint integrity in metal-to-metal and composite material fastening.
Specification Summary & Compliance
This screw features a 6-32 UNC coarse thread with Class 3A fit for precise dimensional accuracy, a length of 7/16 inch, and a head diameter of 0.262 inch. Manufactured in accordance with ASME B18.3 and ASTM F835 specifications, it ensures consistent performance. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety standards for global industrial use.
