Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and extended service life.
- Enhanced durability and wear resistance from the black oxide finish, which also provides a sleek, non-reflective appearance.
- Precise and reliable fastening ensured by the Class 3A thread fit, minimizing the risk of loosening under vibration.
- High mechanical strength with 70,000 PSI tensile and 35,000 PSI shear strength, supporting demanding loads and stresses.
- Secure and efficient installation using the hex socket drive, allowing for high torque application in confined spaces.
- Accurate component alignment due to the standardized shoulder diameter and length, facilitating consistent assembly.
- Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use.
Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in precision assemblies, such as maintaining alignment in rotating machinery and supporting pivoting components. The Class 3A thread fit and coarse UNC thread provide robust, vibration-resistant connections, reducing maintenance needs in automotive, aerospace, and industrial equipment. The black oxide finish on the corrosion-resistant material extends lifespan in humid or chemically aggressive settings, while the socket head with hex drive enables quick, secure fastening even in tight spaces. Its high tensile and shear strength ensures reliability under dynamic loads, making it a trusted choice for precision shoulder bolt applications where failure is not an option.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A fit for precise dimensional accuracy, including a shoulder diameter of 5/32" and thread length of 3/16". Manufacturing conforms to specified tolerances for shoulder diameter and length. It is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting stringent environmental and safety regulations for industrial use.
