• High load-bearing capability with 70,000 psi tensile strength and 35,000 psi shear strength for demanding applications
• Secure fastening and vibration resistance from Class 3A thread fit and knurled head texture
• Easy installation and removal using standard 5/64" hex drive tools
• Durable performance backed by Rockwell B55 hardness for long-term reliability
• Compliance with global standards including RoHS 3 and REACH for safe, regulated use

Professional Applications & Engineering Value

This 18-8 Stainless Steel shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery, robotics, and precision equipment. The 1" shoulder length provides consistent spacing for rotating components like gears and pulleys, reducing wear and misalignment. With 2-56 UNC coarse threads and Class 3A thread fit, it ensures secure fastening even under vibration, while the hex drive and knurled head allow for quick, tool-friendly installation. The high tensile and shear strength makes it suitable for heavy-duty applications where failure is not an option, and the corrosion-resistant material ensures longevity in moist or chemical-exposed environments.

Specification Summary & Compliance

This shoulder screw features a 2-56 UNC thread with Class 3A fit for precision threading, a shoulder diameter of 3/32" with tolerance of -0.004" to -0.002", and shoulder length of 1" with tolerance of -0.005" to 0.005". It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial and commercial use.
