Professional Applications & Engineering Value
This 316 Stainless Steel Shoulder Screw is engineered to address critical alignment and durability challenges in industrial machinery. The 1/2"-13 UNC coarse thread and Class 3A fit provide a secure, vibration-resistant fastening solution, while the precisely machined shoulder ensures accurate positioning of moving parts such as gears, pulleys, and linkages. The socket head with knurling and 5/16" hex drive allows for high-torque installation in confined spaces, reducing assembly time. Its high tensile and shear strength makes it suitable for heavy-duty applications in automation, automotive, and manufacturing equipment, where reliability and corrosion resistance are paramount.
Specification Summary & Compliance
This shoulder screw features a 1/2"-13 UNC coarse thread with Class 3A fit, a shoulder diameter of 5/8" (tolerance: -0.004" to -0.002"), and a shoulder length of 1 1/2" (tolerance: -0.005" to 0.005"). Manufactured in compliance with ASME B18.3 specifications, it also meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safety and regulatory adherence for global industrial use.
