• Exceptional mechanical strength offering 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable performance under high-stress conditions.
• Precise and secure assembly with Class 3A thread fit and UNC coarse threads, ensuring tight tolerances and reduced risk of loosening.
• Enhanced grip and easy manual adjustment provided by the knurled head texture, facilitating installation and removal without slippage.
• High torque capability via the hex socket drive (3/32"), allowing for secure fastening with standard tools.
• Accurate component alignment due to the controlled shoulder diameter and length tolerances, maintaining part positioning in assemblies.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safety and regulatory acceptance for international markets.

Professional Applications & Engineering Value

This 316 stainless steel shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and corrosive operational settings. The UNC coarse threads with Class 3A fit provide a secure, vibration-resistant connection, minimizing the risk of thread stripping in dynamic applications. The knurled hex socket head enhances grip for manual adjustments in tight spaces, while the precisely machined shoulder ensures consistent component alignment, reducing wear and misalignment in rotating assemblies. With a Rockwell B79 hardness and high tensile strength, it withstands heavy loads and repetitive stress, making it a reliable choice for industrial equipment, medical devices, and marine applications where corrosion resistance and durability are paramount.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for precision assembly. Key dimensional tolerances include a shoulder diameter of 3/16" (tolerance: -0.004" to -0.002") and shoulder length of 1/8" (tolerance: -0.005" to 0.005"), ensuring consistent performance. The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for regulated industrial and international use.
