Professional Applications & Engineering Value
This 316 Stainless Steel Shoulder Screw is engineered to address critical challenges in precision assemblies. The UNC coarse thread and Class 3A fit ensure rapid, secure fastening with minimal risk of cross-threading, ideal for high-vibration environments. The knurled head and hex socket drive facilitate easy handling and torque application, even in confined spaces. Its corrosion-resistant properties make it suitable for marine, chemical processing, and food-grade equipment, where durability and hygiene are paramount. The precisely machined shoulder acts as a reliable pivot or spacer in machinery, reducing wear and maintaining alignment in rotating assemblies, thereby extending equipment life and reducing maintenance cycles.
Specification Summary & Compliance
This shoulder screw features a 10-24 UNC coarse thread with a Class 3A thread fit for high precision. The shoulder diameter is 1/4" with a tolerance of -0.004" to -0.002", and the shoulder length is 5/8" with a tolerance of -0.005" to 0.005".
