• Reliable thread engagement and vibration resistance through fully threaded M5 coarse (0.8mm pitch) Class 6g metric threading
• Broad temperature compatibility from -20° to 180°F for diverse operational conditions
• 4500 psi tensile strength provides dependable mechanical performance in plastic assembly applications
• Standardized dimensions and interchangeability ensured by DIN 912 compliance
• Environmental regulation compliance with RoHS 3 and REACH for global supply chain integration

Professional Applications & Engineering Value

These M5 socket head cap screws deliver exceptional value in applications requiring non-conductive, non-corrosive plastic fasteners. The Polypropylene Plastic construction combined with Class 6g thread fit ensures reliable performance in electrical enclosures, food processing equipment, and chemical handling systems where metal fasteners would corrode or cause galvanic reactions. The fully threaded design and coarse thread pitch provide superior holding power in plastic and composite materials, while the 4mm hex drive allows for efficient installation in confined spaces. Meeting DIN 912 standards, these screws offer consistent dimensional accuracy for replacement and OEM applications across automotive, electronics, and industrial machinery sectors.
