Professional Applications & Engineering Value

This 10-32 UNF thread socket head cap screw is engineered to address common challenges in industrial settings where metal fasteners are unsuitable. The Polypropylene Plastic material provides inherent resistance to a wide range of chemicals, solvents, and corrosive agents, making it perfect for applications in chemical processing, food and beverage equipment, and outdoor installations. Its off-white color and non-conductive properties are ideal for electrical enclosures and consumer products. The fine thread and Class 2A fit ensure a tight, reliable seal that resists loosening under vibration, a critical feature in machinery and automotive components. The 2" length and fully threaded design offer versatile clamping capabilities for securing panels, brackets, and assemblies where adjustability and full grip are required.

Specification Summary & Compliance

This screw features a 10-32 UNF fine thread with a Class 2A thread fit for precise dimensional accuracy and reliable performance. It is manufactured in accordance with standard UNF thread specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free from hazardous substances and safe for use in various industrial and consumer applications.
