S-92235A526 1/2"-13 x 3/4" Flanged Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 140,000 PSI ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in demanding applications.
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in harsh industrial environments and minimizing maintenance needs.
• Precise Class 3A thread fit guarantees tight, secure fastening with minimal play, enhancing joint integrity and vibration resistance.
• Integrated flange design eliminates the need for separate washers, simplifying installation and providing a larger bearing surface for improved load distribution.
• Heavy-duty Rockwell C39 hardness offers excellent wear resistance, maintaining thread form and drive integrity through repeated use.
• Coarse UNC threads enable quick assembly and disassembly, reducing labor time while providing strong holding power in a variety of materials.
• Full threading along the 3/4" length allows for adjustable engagement depth, offering flexibility in assembly and accommodating varying material thicknesses.

Professional Applications & Engineering Value

Engineered for industrial machinery, heavy equipment, and structural assemblies, this black-oxide alloy steel socket head cap screw addresses critical challenges like vibration loosening and environmental degradation. The flange-style design distributes clamp load efficiently, preventing surface damage and reducing stress concentration—ideal for high-cycle applications. With its coarse UNC thread and Class 3A fit, it ensures rapid installation and reliable torque transmission, minimizing downtime in production lines. The hex drive socket allows for high-torque application in confined spaces, while the fully threaded configuration supports versatile mounting requirements, from securing motor mounts to framing in corrosive settings.
