- Superior Corrosion Resistance – The black oxide finish provides durable protection against rust and wear in demanding industrial environments.
- Precision Fit & Alignment – Class 3A thread fit and standard shoulder diameter ensure accurate positioning and reduced assembly play.
- Enhanced Grip & Easy Installation – Knurled head and 1/8" hex drive allow for secure tool engagement and straightforward tightening.
- High Durability & Material Integrity – Alloy steel construction with Rockwell C32 hardness offers long-term performance under repetitive loads.
- Wide Compatibility – 10-24 UNC coarse thread and right-hand design facilitate quick assembly with standard components.
- Regulatory Assurance – Compliant with ASME B18.3, RoHS 3, and REACH, meeting strict quality and environmental standards.
Professional Applications & Engineering Value
This alloy steel shoulder screw is engineered to address critical alignment and load distribution challenges in precision assemblies. The 3/8" shoulder length and standard shoulder fit provide a stable bearing surface, minimizing misalignment in machinery, automotive, and automation systems. The 10-24 UNC coarse thread ensures rapid installation and high resistance to vibration loosening, while the black oxide finish enhances corrosion resistance in humid or abrasive conditions. With 140,000 psi tensile strength and Rockwell C32 hardness, it withstands dynamic stresses in pivots, gears, and linkages, reducing maintenance needs and improving operational reliability. Ideal for high-performance industrial fasteners requiring exact tolerances and durability.
Specification Summary & Compliance
This shoulder screw adheres to Class 3A thread fit for precise engagement and features a shoulder diameter tolerance of -0.004" to -0.002" with length tolerance of -0.005" to 0.005". Manufactured in compliance with ASME B18.3 and ASTM A574 specifications, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safety and sustainability in industrial use.
