• Exceptional mechanical strength offering 70,000 psi tensile strength and 35,000 psi minimum shear strength for high-stress applications.
• Precise Class 3A thread fit ensures reliable, secure fastening with minimal backlash in assemblies.
• Enhanced wear resistance and reduced light reflection from the black oxide finish, improving durability and usability.
• Easy installation and removal with a knurled socket head and 3/32" hex drive, providing a secure grip for efficient maintenance.
• Accurate component alignment due to the standardized shoulder diameter and length, facilitating smooth rotational movement.
• Compliance with environmental and safety standards including RoHS 3 and REACH, ensuring safe use in regulated industries.

Professional Applications & Engineering Value

This 316 stainless steel shoulder screw with a black oxide finish is engineered to address common industrial challenges such as corrosion, misalignment, and mechanical failure. The 6-32 UNC coarse thread and Class 3A fit provide a tight, reliable connection that resists loosening under vibration, making it ideal for precision machinery, automotive assemblies, and electronic enclosures. The knurled socket head with a hex drive allows for easy torque application in confined spaces, while the robust shoulder design ensures accurate positioning of moving parts like gears and pulleys. Its high tensile strength and corrosion resistance reduce maintenance needs, offering long-term reliability in demanding environments such as marine, chemical processing, and outdoor equipment.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a precise Class 3A fit for tight tolerances. Key dimensions include a shoulder diameter of 3/16" (tolerance: -0.004" to -0.002") and shoulder length of 3/8" (tolerance: -0.005" to 0.005"), ensuring consistent performance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmental safety and regulatory requirements in industrial applications.
