S-8077A689 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 performance under high stress.
• Precise alignment and reduced wear ensured by the 3/16" shoulder with controlled diameter and length tolerances.
• Secure, non-slip installation provided by the knurled socket head and 3/32" hex drive, preventing tool slippage.
• High-accuracy thread engagement with Class 3A fit and coarse UNC threads for fast assembly and vibration resistance.
• Enhanced durability and minimal reflectivity from the black oxide finish, which also adds mild corrosion protection.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and responsible manufacturing.

Professional Applications & Engineering Value

This 6-32 UNC shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 316 stainless steel material provides excellent resistance to chemicals and moisture, making it suitable for machinery, marine equipment, and food processing systems. The 3/16" shoulder length and precise diameter tolerances allow for accurate component positioning, reducing wear on moving parts and preventing misalignment. Combined with a Class 3A thread fit and coarse UNC threading, it ensures quick, secure fastening even in high-vibration environments. The black oxide finish on the socket head adds an extra layer of protection and reduces glare, while the knurled texture improves grip during installation. These features make it a reliable choice for precision assemblies, pivots, and rotating mechanisms where strength and corrosion resistance are paramount.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. The shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005", ensuring consistent performance. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for regulated industries and environmental safety.
