S-91271A714 1/2"-13 x 1 1/4" IFI 115 12-Point Screws

Key Features & Benefits at a Glance

• Exceptional torque transmission with an external 12-point drive and 1/2" drive size, enabling secure tightening in high-stress applications.
• Superior strength and durability from alloy steel construction, offering a high tensile strength of 170,000 psi and Rockwell C37 hardness for reliable performance.
• Precise and secure fastening with Class 3A thread fit and UNC coarse threading, ensuring tight tolerances and reduced risk of loosening under vibration.
• Enhanced load distribution and stability due to the integrated flange design, eliminating the need for a separate washer and simplifying assembly.
• Full threading along the 1-1/4" length provides consistent grip and allows for adjustable positioning in deep or variable material thicknesses.
• Right-hand thread direction and coarse spacing facilitate quick installation and are ideal for general industrial use where speed is crucial.
• Compliance with industry standards including IFI 115, RoHS 3, and REACH, ensuring environmental safety and meeting rigorous quality benchmarks for global supply chains.

Professional Applications & Engineering Value

This 12-point flange screw is engineered to address critical challenges in heavy-duty industrial applications, such as machinery assembly, automotive systems, and structural frameworks. The alloy steel composition, combined with a Rockwell C37 hardness and 170,000 psi tensile strength, ensures resistance to shear forces and fatigue, reducing failure risks in high-vibration environments. The external 12-point drive allows for maximum torque application without stripping, while the UNC coarse thread and Class 3A fit provide precise engagement, minimizing play and enhancing joint integrity. The flanged design distributes clamping force evenly, protecting surfaces and streamlining installation. Ideal for high-torque scenarios, this screw delivers reliable performance where durability and compliance with standards like IFI 115 are paramount.
