Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel construction and Black Oxide finish, ideal for harsh industrial environments.
- Enhanced durability and load-bearing capacity from 70,000 psi tensile strength and 35,000 psi minimum shear strength.
- Precise alignment and reduced wear thanks to the Class 3A thread fit and standard shoulder fit for accurate component positioning.
- Secure, non-slip installation with a knurled socket head and hex drive, ensuring firm tool grip during assembly.
- Reliable performance in high-stress applications due to Rockwell B79 hardness and coarse UNC threads for quick assembly.
- Consistent dimensional accuracy with tight tolerances on shoulder diameter and length, minimizing assembly errors.
- Compliance with environmental and safety standards, including RoHS 3 and REACH, for global market acceptance.
Professional Applications & Engineering Value
This 316 Stainless Steel shoulder screw with a Black Oxide finish is engineered to address common industrial challenges such as corrosion, misalignment, and mechanical failure. The UNC coarse thread and Class 3A thread fit ensure quick, secure fastening in high-vibration environments, while the precise 1 3/4" shoulder length provides stable support for rotating parts like bearings and pulleys. Its high tensile and shear strength makes it suitable for machinery, automotive, and aerospace applications, reducing maintenance needs and extending equipment life. The knurled socket head enhances grip for efficient installation, supporting productivity in assembly lines.
Specification Summary & Compliance
This shoulder screw features a Class 3A thread fit with UNC coarse threads, ensuring tight tolerances for reliable performance. Dimensions include a shoulder diameter of 7/32" (tolerance: -0.004" to -0.002") and shoulder length of 1 3/4" (tolerance: -0.005" to 0.005"). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and regulated industries.
