- Enhanced durability and wear resistance from the black oxide finish, providing long-lasting performance and reduced maintenance
- High strength reliability with 70,000 psi tensile strength and 35,000 psi shear strength for demanding mechanical applications
- Precise alignment and secure fit thanks to the 3/16" shoulder diameter and Class 3A thread fit, minimizing play and vibration
- Easy installation and removal with the socket head and hex drive style, allowing for efficient assembly in confined spaces
- Improved grip during manual adjustment from the knurled head texture, reducing slippage and enhancing operator control
- Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in regulated industries
Professional Applications & Engineering Value
This 8-32 UNC shoulder screw in 316 stainless steel with a black oxide finish is engineered to address critical challenges in precision machinery and industrial equipment. The coarse UNC threads and Class 3A fit ensure secure fastening with minimal risk of loosening under vibration, while the 3/16" shoulder diameter provides exact alignment for rotating parts like bearings, pulleys, and gears. The high tensile and shear strength supports heavy-duty applications, from automotive assemblies to conveyor systems, where corrosion resistance and longevity are paramount. Its socket head design and knurled texture facilitate quick maintenance, reducing downtime in production environments.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A fit for tight tolerances, ensuring reliable performance in precision assemblies. Dimensions include a shoulder diameter of 3/16" with a tolerance of -0.004" to -0.002" and shoulder length of 3" with -0.005" to 0.005" tolerance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting use in regulated sectors without environmental concerns.
