• Enhanced durability and wear resistance from the black oxide finish, providing long-lasting performance under heavy use
• High tensile and shear strength (70,000 psi tensile, 35,000 psi shear) ensures reliable load-bearing in demanding applications
• Precise Class 3A thread fit delivers secure fastening with minimal backlash for vibration-resistant assemblies
• Knurled socket head design allows for easy installation and removal with standard hex tools, reducing assembly time
• Accurate shoulder dimensions with tight tolerances ensure consistent alignment and smooth rotation in pivoting mechanisms
• Compliance with major standards including ASME B18.3, RoHS 3, and REACH for guaranteed quality and environmental safety

Professional Applications & Engineering Value

This 316 stainless steel shoulder screw with black oxide finish is engineered to address critical challenges in industrial machinery, automation, and precision equipment. The 10-24 UNC coarse thread and Class 3A thread fit provide exceptional holding power in high-vibration environments, preventing loosening in conveyor systems, robotic arms, and assembly fixtures. The precisely machined shoulder acts as a reliable pivot or spacer, maintaining alignment in rotating components like bearings and linkages. Made from corrosion-resistant 316 stainless steel, it withstands exposure to moisture, chemicals, and extreme temperatures, reducing maintenance downtime in manufacturing and marine applications. The socket head with hex drive ensures easy access in confined spaces, streamlining installation and service workflows for engineers and maintenance teams.

Specification Summary & Compliance

This shoulder screw features a 10-24 UNC coarse thread with Class 3A precision fit, ensuring tight tolerances for reliable engagement. Shoulder diameter and length maintain strict tolerances (e.g., diameter: -0.004" to -0.002", length: -0.005" to 0.005") for consistent performance in precision assemblies. Manufactured in compliance with ASME B18.3 specifications for dimensional accuracy and mechanical properties. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial use.
