Professional Applications & Engineering Value
Engineered for demanding industrial settings, these 4-40 UNC Nylon Plastic Socket Head Cap Screws address critical challenges like galvanic corrosion and electrical isolation. The nylon material inherently resists moisture, chemicals, and oxidation, eliminating the need for additional coatings or maintenance. With a coarse UNC thread and Class 2A fit, they provide rapid assembly and vibration resistance in plastics, composites, or soft metals. The socket head design with a 3/32" hex drive ensures torque control in tight enclosures, commonly used in electronics, automotive controls, and medical devices where non-conductive, temperature-resistant fasteners are essential for reliability and safety.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. Manufactured in the inch system, it features a fully threaded 4-40 size, right-hand direction, and standard socket head profile. Compliance includes RoHS 3 (2015/863/EU), ensuring it is free from hazardous substances for environmentally responsible sourcing.
