S-96242A506 1/4"-20 x 3/4" 12-Point Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and extended service life
• Exceptional torque transmission via the external 12-point drive, minimizing tool slippage and ensuring secure installation
• High tensile strength of 170,000 PSI provides reliable load-bearing capacity for demanding structural applications
• Precision Class 3A thread fit ensures consistent, vibration-resistant fastening with superior engagement
• Integrated flange design eliminates the need for a separate washer, distributing clamp load evenly and speeding assembly
• Robust Rockwell C37 hardness offers excellent wear resistance and durability under repetitive stress
• Coarse UNC threading allows for quick installation and reduced cross-threading risks in industrial settings

Professional Applications & Engineering Value

Engineered for high-stakes industrial applications, this 12-point flanged screw delivers critical performance where reliability is non-negotiable. The 18-8 stainless steel material combats corrosion in chemical, marine, and outdoor installations, while the external 12-point drive accommodates high-torque tools without rounding, crucial for machinery, heavy equipment, and structural frameworks. Its Class 3A thread fit and fully threaded design maintain clamping force under dynamic loads, preventing loosening in vibrating systems. The built-in flange enhances joint integrity by increasing the bearing surface, making it a go-to industrial fastener for assembly lines, automotive components, and construction projects requiring heavy-duty screw solutions.
