Professional Applications & Engineering Value
Engineered for electrical enclosures, control panels, and lightweight assemblies, these nylon plastic fillister head screws solve critical industry challenges. The non-conductive properties eliminate electrical grounding concerns while the chemical-resistant nylon material withstands exposure to oils, solvents, and moisture. The slotted drive style allows for quick installation with standard tools, and the fully threaded UNC coarse design ensures maximum grip length in plastic and soft materials. Ideal for applications where metal fasteners could cause galvanic corrosion or interfere with electronic components, these RoHS compliant screws deliver consistent performance in automotive, electronics, and consumer goods manufacturing.
Specification Summary & Compliance
This fastener features 1/4"-20 UNC coarse threads with Class 2A thread fit tolerances for precise engagement. The rounded fillister head measures 0.414" in diameter with a 0.237" height, providing a high, narrow profile. Manufactured to standard inch system specifications with right-hand threading and full thread coverage. Compliant with RoHS 3 (2015/863/EU) regulations, ensuring environmental safety and restricted substance control.
