• Secure and efficient installation with the hex socket drive and knurled head texture, preventing cam-out and providing excellent grip.
• Consistent thread engagement ensured by the Class 2A thread fit and 10-24 UNC coarse thread, facilitating quick assembly.
• Environmental compliance meeting RoHS 3 and REACH standards, making it suitable for global markets and eco-sensitive projects.
• Enhanced durability from Rockwell B55 hardness, resisting deformation under stress for extended service life.

Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to address critical alignment and durability challenges in precision machinery. The 18-8 stainless steel material provides excellent corrosion resistance, ideal for applications in moist or chemically aggressive settings like food processing or marine equipment. The 2" shoulder length with minimal tolerances ensures precise shaft alignment in assemblies, reducing vibration and component wear. Combined with a coarse thread and Class 2A fit, it allows for rapid, secure fastening in high-vibration environments such as automotive or robotics. The hex socket drive and knurled head enhance installation efficiency, minimizing tool slippage and downtime. This screw delivers reliable performance in industrial shoulder screw applications, from pivots to guides, where strength and precision are paramount.
