S-96242A738 3/8"-16 x 1 1/2" 12-Point Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 450 stainless steel construction, ideal for harsh industrial environments and reducing maintenance costs.
• Superior tensile strength of 170,000 psi ensures reliable performance under high-stress conditions, minimizing the risk of fastener failure.
• Precise Class 3A thread fit provides a secure, vibration-resistant connection for critical assemblies.
• Integrated flange design eliminates the need for a separate washer, simplifying installation and providing a larger bearing surface.
• External 12-point drive allows for high-torque application with standard tools, enabling efficient assembly and disassembly.
• Rockwell C37 hardness offers excellent wear resistance, extending the service life of the screw in demanding applications.
• Coarse UNC threading facilitates quicker installation and is less prone to cross-threading compared to fine threads.

Professional Applications & Engineering Value

This 12-point flanged screw is engineered to address common challenges in heavy machinery, automotive, and construction sectors where vibration loosening and corrosion are primary concerns. The use of 450 stainless steel provides a robust barrier against rust and chemical exposure, ensuring long-term integrity in outdoor or chemically aggressive settings. The Class 3A thread fit and coarse UNC threading deliver a tight, reliable seal that resists back-off under dynamic loads, while the integral flange distributes clamping force evenly to protect sensitive surfaces. This combination of high tensile strength and partial threading makes it an optimal choice for applications requiring a secure grip on thick materials without compromising on durability or ease of maintenance.

Specification Summary & Compliance

This screw adheres to UNC (Unified Coarse) thread standards with a precise Class 3A thread fit for superior dimensional accuracy. Key specifications include a 3/8"-16 thread size, 1 1/2" length, and 5/8" flange diameter. The manufacturing process ensures compliance with industry standards for mechanical properties, including the specified Rockwell C37 hardness and 170,000 psi tensile strength. The 450 stainless steel material is compliant with RoHS and REACH directives, making it suitable for global industrial use where environmental and safety regulations are critical.
