Captive Panel Screw - Type 4
The Captive Panel Screw type 4 is designed to remain attached even if unscrewed when used with a captive panel retainer. Type 4 Captive Panel Screws, like other types of captive panel screws, are most commonly used on control panel doors to keep them screwed shut during normal operating conditions.
When access to parts is needed, unthreading the screw allows for the door to be opened, while the retainer keeps the captive panel screw attached to the door. A perfect solution to prevent a lost screw from becoming lost during a field repair or creating a safety hazard.
