S-96242A502 1/4"-20 x 1/2" 12-Point Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance thanks to 18-8 Stainless Steel construction, ideal for harsh environments
• Superior torque transmission and reduced slippage with the external 12-point drive and 5/16" drive size
• Enhanced load distribution and component stability provided by the integrated flange, eliminating the need for a separate washer
• Reliable, high-strength fastening with a tensile strength of 170,000 psi and Rockwell C37 hardness for demanding applications
• Precise and secure thread engagement ensured by the Class 3A thread fit and UNC coarse thread profile
• Full-length threading for maximum grip and holding power along the entire 1/2" length
• Simplified installation and removal with the right-hand thread direction and standard 1/4"-20 UNC size

Professional Applications & Engineering Value

This 12-point flanged screw is engineered to solve critical challenges in heavy-duty assembly. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for applications in chemical processing, marine environments, and outdoor equipment. The external 12-point drive offers superior contact with driving tools, minimizing cam-out and enabling high-torque installation without damaging the fastener head. The integral flange distributes clamping force over a wider area, reducing surface pressure and preventing loosening under vibration, which is vital in machinery, automotive subsystems, and structural frameworks. Combined with the Class 3A thread fit and coarse UNC threading, this screw ensures rapid assembly and a reliable, vibration-resistant connection in high-stress environments.

Specification Summary & Compliance
