• Precise component alignment ensured by the 1-1/2" shoulder with tight length tolerances (±0.005") for stable and accurate assembly.
• High-strength performance with 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable load-bearing in demanding applications.
• Secure, non-slip installation provided by the knurled socket head and hex drive, allowing for high torque application without stripping.
• Consistent thread engagement with Class 2A UNC coarse threads for easy starting and robust fastening in a wide range of materials.
• Environmental regulation compliance meeting RoHS 3 and REACH standards, ensuring safety and suitability for global markets.
• Durable, long-lasting finish with a Rockwell B55 hardness, providing excellent wear resistance and extended service life.

Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to solve critical alignment and durability challenges in industrial settings. The 1-1/2" shoulder length with minimal tolerance variation acts as a precise pivot or spacer, preventing lateral movement in assemblies such as rotating machinery, conveyor systems, and precision instruments. Manufactured from 18-8 stainless steel, it offers inherent corrosion resistance, reducing maintenance needs in moist or chemically aggressive environments. The coarse UNC thread and Class 2A fit facilitate quick assembly while maintaining strong holding power. Combined with a knurled socket head for secure tool engagement, this screw ensures reliable performance in applications demanding exact positioning, high shear strength, and repeatable accuracy, making it a trusted component for OEMs and maintenance teams.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement. The shoulder diameter and length maintain tight tolerances (e.g., shoulder length: -0.005" to 0.005") to ensure precision alignment. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in products requiring environmental safety and material restrictions.
