Professional Applications & Engineering Value

This 10-32 UNF Socket Head Cap Screw is engineered to address critical sealing and durability challenges in high-pressure fluid systems, automotive assemblies, and precision machinery. The integration of a Viton® Fluoroelastomer O-Ring creates a reliable seal against leaks up to 1500 psi, while the 18-8 Stainless Steel body resists corrosion from chemicals, moisture, and UV exposure. Its fine UNF threads with Class 3A fit provide vibration resistance and precise alignment in applications requiring minimal clearance, such as hydraulic components, pump housings, and aerospace fixtures. The fully threaded design ensures uniform stress distribution, enhancing joint integrity under dynamic loads and thermal cycling from -20° to 400°F, making it a versatile solution for OEM and MRO requirements.

Specification Summary & Compliance

This screw features a 10-32 UNF fine thread with Class 3A fit for high-precision assembly, manufactured in compliance with ASME B18.3, ISO 4762, and DIN 912 standards. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in restricted substance-sensitive industries. The fully threaded, 3/8" length design maintains consistent engagement, while the 5/32" hex drive and standard socket head profile facilitate secure torque application.
