S-8077A226 8-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and extended service life.
• Enhanced durability and reduced light reflection from the Black Oxide finish, providing added wear resistance.
• High mechanical strength with 70,000 psi tensile and 35,000 psi shear strength, ensuring reliable performance under heavy loads.
• Precise thread engagement with Class 3A fit, offering tighter tolerances for secure fastening in critical assemblies.
• Easy installation and grip thanks to the knurled socket head and hex drive, preventing tool slippage during torque application.
• Accurate component alignment with a standardized shoulder diameter and length, minimizing misalignment in mechanical systems.
• Compliance with environmental regulations, meeting RoHS 3 and REACH standards for safe and sustainable use.

Professional Applications & Engineering Value

This 8-32 UNC Thread Shoulder Screw is engineered to address common industrial challenges such as component misalignment, corrosion-induced failure, and assembly inefficiency. Made from 316 Stainless Steel and finished with Black Oxide, it resists corrosive agents in demanding settings like marine, chemical processing, and outdoor machinery. The coarse UNC threading and Class 3A fit ensure quick, secure fastening with minimal risk of cross-threading, while the knurled socket head enhances grip for high-torque applications. Its robust shoulder design provides precise pivoting or spacing in assemblies, reducing wear and maintenance costs in automation, aerospace, and precision equipment.

Specification Summary & Compliance

This shoulder screw adheres to UNC coarse thread standards with a Class 3A thread fit for high precision. Key dimensional tolerances include a shoulder diameter of 7/32" (tolerance: -0.004" to -0.002") and shoulder length of 2" (tolerance: -0.005" to 0.005"). It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory adherence for industrial fastening solutions.
