S-96126A173 10-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction and a passivated finish.
• Exceptional mechanical strength with a 70,000 psi tensile strength and Rockwell B79 hardness for reliable performance under high-stress loads.
• Precise assembly and alignment enabled by a Class 2A thread fit and a precise shoulder with minimal diameter tolerance.
• Secure and flush installation in confined spaces using the standard socket head and 1/8" hex drive.
• Stable pivot and spacer function provided by the long, 1-1/4" shoulder length with tight length tolerance.
• Reliable fastening in fine-thread applications due to the 10-32 UNF fine thread and right-hand thread direction.
• Compliance with global environmental standards, being RoHS 3 and REACH compliant for use in regulated industries.

Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve critical alignment and durability challenges in demanding industrial applications. Manufactured from 316 stainless steel and featuring a passivated finish, it offers outstanding resistance to corrosion, chemicals, and high-moisture environments, making it ideal for machinery, food processing equipment, and marine applications. The 1-1/4" shoulder length provides a stable, unthreaded bearing surface that acts as a precise pivot, axle, or spacer, reducing wear and maintaining alignment in assemblies. Combined with the 10-32 UNF fine thread and Class 2A thread fit, it ensures vibration resistance and secure fastening in components requiring fine adjustment. The socket head design allows for easy installation with a standard hex key, even in tight spaces, enhancing assembly efficiency and reliability.

Specification Summary & Compliance

This shoulder screw adheres to precise dimensional standards, including a Class 2A thread fit for consistent engagement and a precise shoulder fit with a diameter tolerance of -0.001" to 0" and length tolerance of 0" to 0.002". It conforms to UNF thread standards and is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of hazardous substances for safe use in various industrial sectors.
