S-92235A525 3/8"-16 x 1 1/2" Flanged Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 140,000 PSI ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Superior corrosion resistance from the black-oxide finish extends service life in demanding industrial environments.
• Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant assemblies with minimal backlash.
• Integrated flange design eliminates the need for separate washers, simplifying installation and distributing load more effectively.
• High hardness rating (Rockwell C39) enhances wear resistance and maintains thread integrity under repeated use.
• 5/16" hex drive allows for high torque application with standard tools, ensuring efficient installation and removal.
• Compliance with RoHS 3 and REACH ensures environmental and safety standards are met for global supply chain integration.

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these Black-Oxide Alloy Steel Socket Head Cap Screws address common challenges in machinery, automotive, and equipment assembly. The 3/8"-16 UNC coarse threads and Class 3A fit provide excellent engagement in both metals and plastics, reducing cross-threading risks and ensuring consistent clamping force. The partially threaded design offers unthreaded shank sections for precise alignment and shear resistance, while the flange distributes pressure to prevent surface damage. With a 140,000 PSI tensile strength and Rockwell C39 hardness, these screws withstand dynamic loads and vibrations, making them ideal for high-stress fastening where reliability is critical.

Specification Summary & Compliance

This socket head cap screw features a 3/8"-16 UNC coarse thread with Class 3A fit for precise thread engagement, and a length of 1 1/2" with a minimum thread length of 1 1/4". Manufactured from alloy steel with a black-oxide surface treatment, it meets industry standards for dimensional accuracy and performance. The product is RoHS 3 (2015/863/EU) compliant with exemption 6(a) for lead as an alloying element in steel, and REACH (EC 1907/2006) compliant, ensuring adherence to environmental and safety regulations.
