Professional Applications & Engineering Value

These 12-point flanged screws are engineered to solve critical fastening challenges in industrial environments where high torque transmission and corrosion resistance are paramount. The 18-8 stainless steel construction provides excellent protection against rust and chemical exposure, making these industrial fasteners ideal for marine, chemical processing, and outdoor applications. The external 12-point drive design allows for maximum torque application without stripping, while the integrated flange eliminates the need for separate washers, reducing assembly time and component count. The Class 3A thread fit ensures precise engagement with mating components, preventing loosening under vibration and maintaining clamping force in heavy machinery, structural assemblies, and high-vibration equipment.

Specification Summary & Compliance

This 3/8"-16 UNC screw features Class 3A thread fit for precision tolerance, right-hand coarse threading, and full threading along the 1" length. The flange diameter measures 5/8" with a 3/8" drive size and 12-point head configuration. Manufactured from 18-8 stainless steel with Rockwell C37 hardness and 170,000 PSI tensile strength, these screws comply with UNC thread standards and are suitable for applications requiring reliable industrial fastening solutions with consistent performance characteristics.
