- Precise and secure fit with Class 3A thread tolerance, ensuring reliable engagement and reduced risk of loosening.
- Easy installation and removal using a standard 5/64" hex drive and a knurled head for improved grip during manual handling.
- Versatile shoulder design with a consistent 3/32" diameter and 1/8" length, providing accurate alignment and pivot points.
- Compliance with environmental regulations, being RoHS 3 and REACH compliant for use in regulated industries.
Professional Applications & Engineering Value
This 316 Stainless Steel shoulder screw with a Black Oxide finish and UNC coarse threading is engineered to address common industrial challenges such as corrosion, misalignment, and mechanical stress. The socket head design with a hex drive allows for efficient torque application in confined spaces, while the knurled texture enhances handling. Its high tensile and shear strength makes it suitable for precision assemblies in machinery, automotive, and electronics, where consistent shoulder dimensions ensure accurate component positioning. The coarse 2-56 UNC thread provides quick assembly and disassembly, reducing downtime in production lines.
Specification Summary & Compliance
This shoulder screw adheres to Class 3A thread fit for precise UNC threading, with shoulder diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005". It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring it is free from hazardous substances. Manufactured from 316 Stainless Steel with a Rockwell B79 hardness, it is designed for reliable performance in various engineering applications.
