S-90337A195 10-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel and passivated finish for long-lasting performance in harsh industrial environments.
• Enhanced space-saving design thanks to the low-profile socket head, ideal for applications with limited clearance.
• High mechanical strength and durability from Rockwell B55 hardness and 70,000 psi tensile strength, resisting deformation under heavy loads.
• Precise alignment and smooth rotation ensured by the Class 2A thread fit and precisely machined shoulder with tight tolerances.
• Secure and efficient installation using the 1/8" hex drive, preventing cam-out and ensuring consistent torque application.
• Reliable fine thread engagement with 10-32 UNF right-hand threads, providing superior vibration resistance in dynamic assemblies.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries.

Professional Applications & Engineering Value

This 10-32 UNF shoulder screw is engineered to address critical challenges in precision machinery, automation, and assembly systems. The 18-8 stainless steel construction, combined with a passivated finish, offers excellent resistance to corrosion and wear, extending service life in demanding conditions. The low-profile socket head design minimizes protrusion, making it ideal for compact spaces in electronic enclosures, robotic arms, and precision instruments. With a fine thread spacing and Class 2A thread fit, it ensures secure fastening and reduces the risk of loosening under vibration. The precisely controlled shoulder diameter and length provide accurate positioning for rotating components, bushings, or linkages, enhancing overall assembly reliability and reducing maintenance needs in industrial applications.

Specification Summary & Compliance

This shoulder screw adheres to Class 2A thread fit tolerances for consistent engagement and features a 10-32 UNF fine thread with right-hand direction. The shoulder dimensions include a diameter of 1/4" (with tolerance -0.001" to 0") and length of 3/8" (with tolerance 0" to 0.002"), ensuring precise fits. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and environmentally responsible use in global markets.
