Key Features & Benefits at a Glance
- Exceptional tensile strength of 150,000 PSI ensures reliable performance in high-stress industrial applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black phosphate coating extends service life in harsh environments, minimizing maintenance needs.
- High hardness rating (Rockwell C32) provides excellent wear resistance and durability under repetitive loads.
- Flanged design eliminates the need for separate washers, simplifying installation and distributing load more effectively.
- External hex drive allows for secure, high-torque installation with standard tools, enhancing assembly efficiency.
- Class 2A thread fit with UNC coarse threading ensures easy engagement and reliable fastening in various materials.
- Compliance with SAE J429, RoHS 3, and REACH guarantees adherence to industry standards and environmental regulations for safe, global use.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, this Grade 8 hex head screw combines black phosphate steel construction with a partially threaded UNC design to address common challenges like vibration loosening and corrosion. The flanged feature provides a larger bearing surface, reducing surface pressure and preventing damage to assembled components. Ideal for heavy machinery, automotive assemblies, and structural applications, its coarse thread spacing and right-hand thread ensure quick installation and reliable hold in tough materials. With a 1-3/4" length and robust external hex drive, it offers consistent performance where high tensile strength and environmental resistance are critical, minimizing downtime and maintenance costs.
Specification Summary & Compliance
This screw meets Class 2A thread fit tolerances per UNC standards, ensuring precise engagement. It conforms to IFI 111 / SAE J429 specifications for Grade 8 fasteners, with verified Rockwell C32 hardness and 150,000 PSI tensile strength. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) for environmental safety, supporting use in regulated industries.
