Professional Applications & Engineering Value

This Alloy Steel Shoulder Screw is engineered to address critical challenges in high-stress applications where alignment precision and mechanical strength are paramount. The 3/4"-16 UNF fine threading with a Class 3A fit provides secure fastening in assemblies subject to vibration, such as in machinery, automotive systems, and precision equipment. The 1" shoulder diameter and 3" shoulder length act as a precise axle or pivot point, reducing wear on moving parts and ensuring accurate component positioning. The Black Oxide finish not only enhances corrosion resistance but also minimizes friction, making it ideal for use in harsh industrial environments. Combined with its 140,000 PSI tensile strength, this shoulder screw delivers reliable performance in demanding engineering scenarios, from robotic arms to conveyor systems, where failure is not an option.
