S-96126A176 10-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction and passivated finish, ideal for harsh chemical and marine environments
• Precise alignment and smooth rotation ensured by the 1/4" diameter shoulder with tight -0.001" to 0" tolerance and smooth texture
• High-strength performance with 70,000 psi tensile strength and Rockwell B79 hardness for reliable load-bearing in mechanical assemblies
• Secure, fine-thread engagement using 10-32 UNF Class 2A threads for vibration resistance and reduced loosening in dynamic applications
• Easy installation in confined spaces with standard hex socket drive requiring only a 1/8" Allen key
• Long-term durability with a 2" shoulder length maintaining precise component spacing under stress
• Compliance with global regulations including RoHS 3 and REACH for use in international markets and sensitive industries

Professional Applications & Engineering Value

This 316 stainless steel shoulder screw is engineered to address critical alignment and corrosion challenges in precision assemblies. The 10-32 UNF fine thread provides superior holding power in thin materials and high-vibration environments like robotics and automation equipment. The passivated finish enhances the innate corrosion resistance of 316 stainless steel, making it suitable for chemical processing, marine hardware, and food machinery where moisture and aggressive agents are present. The precise shoulder diameter with minimal tolerance ensures exact pivot points and bearing surfaces in rotating mechanisms, reducing wear and maintenance cycles. Its hex socket drive allows secure torque application in space-constrained designs, while the 2" shoulder length maintains accurate component spacing in linkages and assemblies. These features combine to deliver reliable performance in demanding industrial shoulder screw applications where precision and longevity are paramount.

Specification Summary & Compliance

This shoulder screw maintains Class 2A thread fit per UNF standards with precise shoulder diameter tolerance of -0.001" to 0" and shoulder length tolerance of 0" to 0.002". Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency. The combination of 70,000 psi tensile strength and controlled hardness provides consistent mechanical performance across production batches.
