Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh or chemical environments.
- Enhanced durability and wear resistance from the black oxide finish, which also reduces light reflection.
- High-strength performance with 70,000 psi tensile and 35,000 psi shear strength for demanding mechanical applications.
- Precise, reliable assembly ensured by Class 3A thread fit for tight tolerances and reduced risk of loosening.
- Secure, non-slip grip provided by the knurled socket head, allowing for easy installation with a hex drive.
- Accurate component alignment thanks to the 1/2" shoulder length with controlled diameter and length tolerances.
- Broad industry compliance with RoHS 3 and REACH regulations, ensuring environmental and safety standards are met.
Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address common industrial challenges such as misalignment, corrosion, and mechanical failure. The UNC coarse threading and Class 3A thread fit provide a secure, vibration-resistant connection in assemblies requiring precise spacing, such as in machinery, electronics, and automotive systems. The black oxide finish not only enhances corrosion resistance but also minimizes galling, extending service life in high-stress environments. With a knurled socket head and hex drive, installation is straightforward, reducing assembly time and improving workflow efficiency in production lines. Ideal for use in pivots, guides, and rotating assemblies, this shoulder screw ensures reliable performance and long-term durability.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. The shoulder diameter tolerance is -0.004" to -0.002", and the shoulder length tolerance is -0.005" to 0.005", ensuring consistent performance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting use in regulated industries. Manufactured from 316 stainless steel with a Rockwell B79 hardness, it delivers reliable strength and corrosion resistance in accordance with industry specifications.
