CAPTIVE PANEL SCREW

A CAPTIVE PANEL SCREW is a non-removable fastener designed to remain attached to a panel, enclosure, or cover even after the screw has been loosened. It helps prevent the screw from being dropped or lost, making it suitable for equipment that requires frequent opening, inspection, maintenance, and reassembly.

Remains Attached After Loosening

The retaining structure keeps the screw secured to the panel even after it has been fully loosened, helping reduce the risk of losing the screw, dropping it inside the equipment, or mixing it with other components during disassembly.

Suitable for Frequent Maintenance and Disassembly

Because the screw remains attached to the panel, there is no need to store loose screws separately when opening the enclosure. This helps shorten inspection, maintenance, servicing, and component replacement time.

Improves Operational Safety

A CAPTIVE PANEL SCREW helps reduce the risk of loose screws falling into circuit boards, fans, or precision mechanisms and causing equipment malfunction, making it especially suitable for electronic and industrial equipment.

Supports Hand Tightening and Tool Fastening

Knurled heads and various drive recesses can be selected to support both quick hand operation and secure tool-assisted tightening.

Multiple Structures and Sizes Available

Sleeves, springs, retaining rings, and different thread specifications can be selected according to panel thickness, mounting-hole dimensions, fastening travel, and operating environment.
