S-8077A517 3-48 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and chemical exposure
• Enhanced durability and wear resistance from the Black Oxide finish, reducing maintenance and replacement frequency
• High load-bearing capacity with 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable performance under stress
• Precise alignment and smooth rotation thanks to the Class 3A thread fit and standard shoulder fit, minimizing play in assemblies
• Secure, non-slip installation with a knurled head and 5/64" hex drive, allowing for firm tool grip and consistent torque application
• Quick assembly in coarse-threaded applications using UNC threading and right-hand direction, speeding up production processes
• Compliance with global safety standards including RoHS 3 and REACH, ensuring environmental and regulatory suitability for industrial use

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 threading and Class 3A fit provide excellent engagement in materials like metals and plastics, reducing the risk of stripping and ensuring long-term stability in dynamic assemblies. Its high tensile and shear strength makes it ideal for precision machinery, automotive components, and electronic enclosures, where consistent performance under vibration and load is critical. The knurled head enhances grip during manual adjustments, while the socket head design allows for compact installation in confined spaces, offering reliable solutions for OEM and MRO applications.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A fit for tight tolerances and reliable thread engagement. Key dimensions include a 3-48 thread size, 5/32" thread length, and 1/8" shoulder diameter with precise tolerances (e.g., shoulder diameter tolerance of -0.004" to -0.002"). It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
