S-90044A261 10-24 x 8" ASTM A574 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress industrial applications, reducing the risk of fastener failure.
• Superior corrosion resistance from the black-oxide finish on alloy steel extends service life in harsh environments, minimizing maintenance needs.
• Precise Class 3A thread fit guarantees secure, vibration-resistant connections, enhancing assembly integrity and reducing loosening over time.
• High hardness rating (Rockwell C37) provides excellent wear resistance, maintaining thread integrity through repeated use and heavy loads.
• Partially threaded design allows for controlled clamping force and easier alignment in assemblies, improving installation efficiency.
• Hex socket drive enables high-torque application with standard tools, offering secure fastening in confined spaces without slippage.
• Compliance with ASTM A574, RoHS 3, and REACH ensures material consistency, environmental safety, and suitability for regulated industries.

Professional Applications & Engineering Value

This 10-24 UNC thread socket head cap screw is engineered from black-oxide alloy steel to address common industrial challenges such as corrosion, high tensile stress, and vibration-induced loosening. The coarse thread spacing and Class 3A thread fit provide rapid assembly and reliable grip in materials like metal and hardened plastics, making it ideal for machinery, automotive, and construction applications. Its partially threaded rod type allows precise load distribution, reducing stress concentration points. With a Rockwell C37 hardness and 170,000 psi tensile strength, it withstands extreme conditions while the hex drive socket head facilitates easy installation with standard wrenches, ensuring long-term durability and reduced downtime in heavy-duty fastening systems.
