S-96242A596 1/4"-28 x 2" 12-Point Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 450 Stainless Steel construction, ideal for harsh industrial environments
• Superior torque transmission through the external 12-point drive, preventing tool slippage during high-torque applications
• Precise thread engagement with Class 3A fit and UNF fine threading, ensuring reliable, vibration-resistant connections
• Enhanced load distribution from the integrated flange, reducing surface pressure and preventing material damage
• High mechanical strength with 170,000 psi tensile strength and Rockwell C37 hardness for demanding structural applications
• Optimized partial threading design providing maximum grip length while maintaining unthreaded shank stability
• Right-hand thread configuration compatible with standard assembly processes and equipment

Professional Applications & Engineering Value

This 12-point screw delivers critical performance advantages in heavy-duty industrial applications where both mechanical strength and environmental resistance are paramount. The 450 Stainless Steel composition provides superior corrosion resistance compared to standard alloys, making it ideal for chemical processing, marine equipment, and outdoor infrastructure. The external 12-point drive system enables higher torque application without cam-out, essential for maintaining joint integrity in vibrating machinery and structural frameworks. With UNF fine threading and Class 3A fit, these screws create precise, tight-sealing connections that resist loosening under dynamic loads. The flanged design eliminates the need for separate washers while providing superior clamping force distribution, particularly valuable in assembly line environments where both reliability and installation efficiency are critical.
