• High tensile strength of 70,000 psi ensures reliable load-bearing capacity and resistance to mechanical failure in demanding applications.
• Precision Class 2A thread fit guarantees smooth assembly, secure fastening, and consistent performance with standard mating components.
• Knurled head texture and hex socket drive provide superior grip and torque application, reducing the risk of tool slippage during installation.
• Long 1 3/4" shoulder length offers precise alignment and acts as a pivot or bearing surface, minimizing wear in moving assemblies.
• Compliance with RoHS 3 and REACH standards ensures environmental safety and meets global regulatory requirements for industrial use.
• Coarse UNC thread design enables quick assembly and disassembly, improving maintenance efficiency in production settings.

Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to address critical alignment and durability challenges in mechanical assemblies. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for applications in moist or chemically aggressive environments, such as food processing equipment, marine hardware, and outdoor machinery. The 1 3/4" shoulder length serves as a precise datum for rotating components like gears, pulleys, and linkages, reducing lateral movement and bearing wear. Combined with a Rockwell B55 hardness and 70,000 psi tensile strength, it withstands high dynamic loads and vibrations, ensuring long-term reliability in automation systems, conveyor setups, and precision instruments. The hex socket drive and knurled head facilitate secure installation in confined spaces, enhancing assembly speed and reducing downtime.
