Captive Panel Screw - Type 6

Captive Panel Screws type 6 are designed to remain attached even if unscrewed when used with a captive panel retainer. This type of captive screws is most commonly used on control panel doors to keep them screwed shut during normal operating conditions. When access is needed, unthreading the captive panel screw allows for the door to be open, while the retainer keeps the screws attached to the door. Captive panel screws are a perfect solution to prevent a lost screw from becoming lost during a field repair or creating a safety hazard.
