Professional Applications & Engineering Value

This acetal plastic captive panel screw system solves critical challenges in industrial panel mounting applications where metal fasteners would cause galvanic corrosion or electrical conductivity issues. The quarter-turn fastening mechanism provides rapid access to internal components while maintaining secure panel retention, making it ideal for maintenance-heavy equipment, electrical enclosures, and instrumentation panels. The rivet mount design creates a permanent mounting point that won't loosen from vibration, while the black acetal plastic construction maintains dimensional stability across the full -40° to 190°F temperature range. This complete captive panel screw assembly eliminates the need for separate hardware sourcing and ensures consistent performance in industrial fastening applications requiring frequent panel removal.

Specification Summary & Compliance

This captive panel screw features precision inch-system dimensions including 1/4" shank diameter, 0.9" length, and 5/8" head diameter with Class 2A thread tolerances. The assembly is manufactured to exacting standards for panel mounting with specified inner hole diameter of 0.438" and outer hole diameter of 0.39". The system is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and chemical restriction adherence for industrial applications worldwide.
