S-96242A716 5/16"-24 x 2 1/2" 12-Point Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 450 stainless steel construction for long-lasting performance in harsh environments
• Superior tensile strength rated at 170,000 PSI to withstand extreme mechanical loads and prevent fastener failure
• Precision Class 3A thread fit ensures secure, vibration-resistant connections with minimal backlash
• Integrated flange design eliminates need for separate washers, reducing assembly time and part count
• External 12-point drive provides high-torque capability and prevents tool slippage during installation
• Optimized partial threading allows for precise clamp load control in critical joint applications
• Rockwell C37 hardness maintains structural integrity under repeated stress and impact conditions

Professional Applications & Engineering Value

These 12-point flanged screws deliver exceptional engineering value in demanding industrial applications where corrosion resistance and high tensile strength are critical. The 450 stainless steel construction provides superior protection against chemical exposure and environmental degradation, while the Class 3A UNF fine threads ensure precise fitment in high-vibration environments like heavy machinery, automotive systems, and industrial equipment. The integrated flange distributes clamping force evenly, preventing surface damage and maintaining joint integrity. The external 12-point drive accommodates high torque requirements, making these partially threaded screws ideal for applications requiring controlled clamp load and reliable fastening in critical assemblies where failure is not an option.
