- Enhanced durability and wear resistance from the Black Oxide finish, providing added protection against abrasion.
- Precise alignment and smooth rotation ensured by the Class 3A thread fit and standard shoulder fit for reliable assembly.
- High-strength performance with 70,000 psi tensile strength and 35,000 psi minimum shear strength for demanding applications.
- Secure and easy installation using the hex socket drive and knurled head, preventing tool slippage and improving grip.
- Consistent dimensional accuracy with tight tolerances on shoulder diameter and length, meeting ASME B18.3 specifications.
- Compliance with environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in industrial settings.
Professional Applications & Engineering Value
This 10-24 UNC shoulder screw in 316 stainless steel with a Black Oxide finish is engineered to address critical challenges in precision machinery, such as misalignment and corrosion-induced failure. The Class 3A thread fit and coarse thread spacing ensure secure fastening in high-vibration environments, while the knurled head and hex drive facilitate quick, tool-resistant installation. Commonly used in robotics, automotive assemblies, and industrial equipment, its 3/8" shoulder length and 1/4" shoulder diameter provide stable pivoting and spacing, reducing wear on moving parts. The combination of Rockwell B79 hardness and high tensile strength makes it a reliable choice for heavy-duty applications, offering long-term performance without compromising on corrosion resistance.
Specification Summary & Compliance
This shoulder screw adheres to Class 3A thread fit and UNC thread standards, with precise dimensions including a thread diameter of 0.19" and shoulder diameter tolerance of -0.004" to -0.002". It meets ASME B18.3 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial reliability.
