S-93705A245 10-24 x 3/4" ASME B18.3 18-8 Stainless Steel Thread-Locking Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
• Exceptional holding power provided by a 70,000 psi tensile strength and Rockwell B70 hardness, preventing fastener failure under high stress.
• Vibration-resistant locking from the integrated nylon patch, ensuring the screw stays securely fastened from -70° to 250°F without loosening.
• Precise and reliable fit due to the UNC Class 3A thread, offering tighter tolerances for high-strength, precision assemblies.
• Easy installation and high torque capability with the standard hex socket head and 5/32" drive, allowing for efficient assembly in confined spaces.
• Versatile coarse threading (UNC) for quicker installation and better performance in a wider range of materials compared to fine threads.
• Full compliance with major industry standards including ASME B18.3, RoHS 3, and REACH, ensuring safety, quality, and environmental responsibility.

Professional Applications & Engineering Value

This 10-24 x 3/4" socket head cap screw is engineered to solve critical fastening challenges in demanding industrial and engineering environments. The core of its value lies in the 18-8 stainless steel material, which provides excellent resistance to rust and corrosion, making it a durable choice for machinery, automotive, and outdoor equipment exposed to moisture or chemicals. The inclusion of a nylon patch thread locker directly addresses the common industrial problem of vibration-induced loosening, maintaining clamp load integrity in dynamic applications from conveyor systems to powertrain assemblies. Its UNC coarse thread and Class 3A fit ensure a strong, precise engagement in metals and other materials, reducing the risk of cross-threading and stripping. The socket head design allows for high torque application in space-restricted areas, providing engineers with a reliable, high-strength fastener that enhances the safety and longevity of the final product.
