S-93996A422 10-32 Shoulder Screws

Key Features & Benefits at a Glance

• Permanent vibration resistance with the integrated nylon patch thread locker, ensuring components stay securely fastened in high-motion environments.
• Superior corrosion resistance from 18-8 Stainless Steel construction, providing long-term reliability in harsh or humid conditions.
• High-strength performance with a 70,000 psi tensile strength and Rockwell B55 hardness, capable of withstanding significant mechanical stress.
• Precise alignment and spacing due to the accurately machined shoulder with a precise fit, reducing assembly play and improving component stability.
• Wide operational temperature range from -70° to 250° F, maintaining locking integrity and material properties in extreme thermal environments.
• Reliable fine-thread engagement with the 10-32 UNF Class 2A thread, offering superior holding power in thin materials and fine-adjustment applications.
• Streamlined assembly using the socket head design, allowing for high-torque installation in confined spaces with standard hex tools.

Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve critical challenges in assembly and motion control systems. The 18-8 stainless steel provides excellent resistance to rust and chemical exposure, making it ideal for food processing, marine, or outdoor equipment. The integrated nylon patch thread locker eliminates the need for separate locking washers or adhesives, preventing loosening under continuous vibration in machinery, automotive subsystems, or conveyor systems. The fine UNF thread and precise shoulder diameter ensure accurate alignment of gears, bearings, and linkages, reducing wear and maintaining operational precision. Its high tensile strength and temperature resilience make it a reliable choice for demanding industrial applications where failure is not an option.

Specification Summary & Compliance

This shoulder screw adheres to Class 2A thread fit tolerances for consistent engagement and is manufactured to uniform engineering standards. It is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety regulations for use in global markets.
