Professional Applications & Engineering Value
This nylon plastic rounded head screw with 4-40 UNC coarse threading addresses critical challenges in electronic assembly and industrial applications where electrical insulation and chemical resistance are paramount. The binding head style with wide bearing surface prevents damage to delicate components while maintaining secure fastening. The fully threaded design ensures consistent engagement depth across various material thicknesses, eliminating the need for multiple screw types. Engineered for temperature resistance across extreme ranges, these screws maintain dimensional stability in both freezing and elevated temperature environments, making them ideal for outdoor equipment, automotive interiors, and consumer electronics where thermal cycling occurs.
Specification Summary & Compliance
Manufactured to precise inch system dimensions with Class 2A thread fit tolerance per UNC standards, ensuring consistent threading performance. The 1/4" length and 0.235" head diameter maintain dimensional accuracy across production batches. Compliant with RoHS 3 (2015/863/EU) regulations, containing no restricted hazardous substances. The right-hand threaded, fully threaded configuration follows industry-standard UNC coarse thread specifications for reliable performance in plastic and soft material applications.
