• Wide temperature tolerance from -40° to 185°F ensures reliable performance in both cold and moderately high-heat applications.
• Easy installation and removal with a standard slotted drive, compatible with common hand tools for efficient maintenance.
• Precise Class 2A thread fit provides consistent engagement and secure fastening in UNC coarse threaded holes.
• RoHS 3 compliance meets environmental regulations, making it suitable for global markets and eco-conscious industries.
• Fully threaded design offers maximum grip and uniform load distribution along the entire 1" length.

Professional Applications & Engineering Value

Engineered for demanding settings, this 4-40 UNC nylon plastic pan head slotted screw delivers critical advantages in electrical and electronic enclosures where non-conductive fasteners are mandatory. The nylon material inherently resists moisture, chemicals, and galvanic corrosion, eliminating the need for additional coatings and reducing long-term maintenance. Its rounded pan head with slotted drive allows for quick assembly in tight spaces, while the coarse UNC threads ensure rapid installation and strong holding power in plastic or soft metal substrates. Ideal for temperature-resistant applications such as control panels, instrumentation, and consumer electronics, this screw maintains dimensional stability across a broad thermal range, preventing loosening under vibration and thermal cycling.

Specification Summary & Compliance

This screw features a 4-40 UNC coarse thread with Class 2A thread fit for standard tolerance and interchangeability. It is fully threaded and measures 1" in length, with a pan head diameter of 0.219" and height of 0.068". Manufactured in compliance with RoHS 3 (2015/863/EU), it is free of restricted hazardous substances, ensuring environmental and regulatory adherence for global supply chains.
