Key Features & Benefits at a Glance
- Permanent vibration resistance with a factory-applied Nylon Patch thread locker that eliminates loosening under dynamic loads.
- Exceptional tensile strength of 120,000 psi ensures reliable, high-load fastening in demanding industrial environments.
- Corrosion-resistant black-oxide finish on alloy steel provides enhanced durability and a professional appearance.
- Wide operational temperature range from -70°F to 250°F maintains locking integrity in extreme conditions.
- Precise Class 3A thread fit and UNC coarse thread design enable quick assembly and superior engagement.
- Secure hex drive (3/32") with a low-profile rounded button head offers easy installation and a flush, snag-free finish.
- Full threading along the 5/16" length allows for maximum adjustability and grip in various material thicknesses.
Professional Applications & Engineering Value
These Black-Oxide Alloy Steel Rounded Head Screws are engineered to solve critical fastening challenges in high-vibration and precision assembly applications. The permanent Nylon Patch thread locker is integrally applied to the UNC coarse threads, providing a reliable, chemical-free locking mechanism that won't back out under sustained stress or thermal cycling. This makes them ideal for industrial machinery, automotive subsystems, and electronic enclosures where maintenance access is limited and failure is not an option. The combination of Rockwell C39 hardness and 120,000 psi tensile strength ensures the fastener withstands shear and tensile forces, while the low-profile rounded head and hex drive facilitate installation in confined spaces without compromising on torque application.
Specification Summary & Compliance
This screw features a #8-32 UNC Coarse Thread with a Class 3A fit for precise, interchangeable assembly. It is fully threaded and measures 5/16" in length. Manufacturing and quality adhere to ASME B18.3, ASTM F835, and MIL-DTL-18240 specifications. The product is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring it meets stringent environmental and safety regulations for global industrial use.
