- Enhanced durability and wear resistance from Rockwell B55 hardness, extending service life in high-stress applications.
- High tensile and shear strength (70,000 psi tensile, 35,000 psi shear) for reliable performance in demanding mechanical assemblies.
- Precise Class 3A thread fit ensures smooth assembly and secure fastening, reducing the risk of cross-threading.
- Secure, non-slip installation with a knurled socket head and 1/8" hex drive, allowing for high-torque applications.
- Black oxide finish provides added corrosion protection and a sleek, professional appearance.
- Compliance with ASME B18.3, RoHS 3, and REACH guarantees quality and environmental safety for global supply chains.
Professional Applications & Engineering Value
This 10-24 UNC shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and rotating assemblies. The 18-8 stainless steel material offers excellent resistance to rust and oxidation, while the black oxide finish enhances surface protection in humid or chemically aggressive settings. The Class 3A thread fit and coarse UNC thread design facilitate quick, accurate installation, minimizing assembly time and preventing thread damage. With a robust shoulder diameter of 1/4" and length of 1 5/8", it provides stable alignment and bearing support in pulleys, gears, and linkages, reducing wear and maintenance costs. Ideal for industrial applications requiring high-strength, corrosion-resistant shoulder screws that meet stringent ASME B18.3 standards.
Specification Summary & Compliance
This shoulder screw features a 10-24 UNC thread with Class 3A fit for precise tolerance, a shoulder diameter of 1/4" (tolerance: -0.004" to -0.002"), and shoulder length of 1 5/8" (tolerance: -0.005" to 0.005"). It is manufactured in compliance with ASME B18.3 specifications and adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and reliability for industrial use.
