Professional Applications & Engineering Value
Engineered for electrical enclosures, PCB mounting, and lightweight assembly systems, these nylon plastic screws solve critical challenges where metal fasteners would cause short circuits or corrosion. The wide rounded binding head distributes clamping force evenly across fragile substrates without cracking plastic housings. With UNC coarse threads and Class 2A fit, they resist vibration loosening while maintaining precise alignment in automated production. The fully threaded design ensures consistent holding power across the entire 5/16" length, making them ideal for variable material thicknesses in electronic components, automotive trim, and HVAC systems operating within the -40° to 185°F range.
Specification Summary & Compliance
Manufactured to inch system standards with 4-40 UNC coarse threads and Class 2A thread fit for consistent dimensional accuracy. Features right-hand threading and fully threaded shank for maximum engagement. Compliant with RoHS 3 (2015/863/EU) environmental regulations, ensuring hazardous substance-free construction for international industrial applications.
