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 strength and 35,000 psi shear strength for demanding mechanical applications.
- Precise and secure thread engagement thanks to the Class 3A thread fit, ensuring reliable fastening in high-vibration settings.
- Easy and non-slip installation with the knurled hex socket head and 3/32" hex drive, allowing for high torque application.
- Accurate component alignment provided by the precisely machined shoulder with standard fit, reducing assembly errors.
- Compliance with international environmental standards including RoHS 3 and REACH, making it suitable for global supply chains.
Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in precision assemblies, such as in machinery, automation, and electronic enclosures. The UNC coarse threading and Class 3A thread fit ensure rapid assembly and vibration resistance, reducing maintenance needs. The black oxide finish not only enhances corrosion resistance but also minimizes galling, which is crucial in high-cycle applications. With a knurled hex socket head, it provides a secure grip for tools, preventing cam-out during installation. The shoulder design allows for precise pivot points or spacers, making it invaluable in linkages, bearings, and rotating mechanisms where alignment and durability are paramount.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. Key dimensional tolerances include shoulder diameter (-0.004" to -0.002") and shoulder length (-0.005" to 0.005"). It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for various industrial and electronic applications.
