S-8077A684 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and extended service life.
• Exceptional mechanical strength offering 70,000 psi tensile and 35,000 psi shear strength for reliable load-bearing in demanding applications.
• Precise and secure assembly ensured by the Class 3A thread fit, minimizing backlash and improving joint integrity.
• Enhanced grip and easy installation with a knurled socket head and 3/32" hex drive, reducing tool slippage.
• Optimized for quick assembly using coarse UNC threads, which are less prone to clogging and cross-threading.
• Durable, wear-resistant surface from the black oxide finish, providing added protection against abrasion and galling.
• 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 machinery, automation systems, and assembly jigs. The UNC coarse thread and Class 3A fit provide tight tolerances that prevent loosening under vibration, a common pain point in dynamic industrial environments. The black oxide finish on the socket head shoulder screw not only enhances corrosion resistance but also reduces friction during installation, protecting the knurled head and hex drive from wear. With a robust shoulder diameter and controlled length tolerances, it serves as an ideal pivot, axle, or spacer in applications requiring exact alignment and high shear strength, such as in conveyor systems, electronic enclosures, and medical devices.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A fit for precise thread engagement. Dimensional accuracy is maintained with shoulder diameter tolerance of -0.004" to -0.002" and shoulder length tolerance of -0.005" to 0.005". The product 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 global supply chains.
