S-90969A110 10-24 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional durability with alloy steel construction providing 140,000 psi tensile strength and Rockwell C30 hardness for reliable performance in demanding environments.
• Secure anti-slip installation thanks to the knurled head texture and hex drive design, ensuring firm grip and reduced tool slippage during assembly.
• Precise thread engagement with Class 3A thread fit and UNC coarse threads, offering superior vibration resistance and consistent fastening in industrial applications.
• Space-saving ultra-low profile socket head allows for use in tight spaces while maintaining high torque capacity and easy access with a 1/8" hex drive.
• Enhanced corrosion resistance from the black oxide finish, prolonging service life and reducing maintenance needs in harsh operating conditions.
• Accurate shoulder alignment with controlled diameter and length tolerances, ensuring smooth pivoting and precise component positioning in machinery.
• Compliance with environmental standards including RoHS 3 and REACH, making it suitable for global supply chains and eco-conscious industries.

Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to address critical challenges in precision assembly and motion control systems. The alloy steel material, combined with a black oxide finish, provides excellent strength and corrosion resistance, ideal for high-stress applications like robotics, automotive fixtures, and conveyor systems. The ultra-low socket head profile and knurled texture prevent cam-out and ensure secure fastening in confined spaces, reducing installation errors. With a Class 3A thread fit and coarse UNC threads, it offers reliable performance in vibrating environments, minimizing loosening and maintenance downtime. These features make it a top choice for engineers seeking durable, compliant components for industrial machinery and equipment.

Specification Summary & Compliance

This shoulder screw adheres to precise dimensional standards, including Class 3A thread fit for tight tolerances and UNC thread specifications. The shoulder diameter and length are manufactured with controlled tolerances (e.g., shoulder diameter: -0.004" to -0.002") to ensure consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for restricted substance-free industrial use. The product meets high-strength requirements with 140,000 psi tensile strength, supporting applications demanding reliability and precision.
