product description

Captivated screws serve the primary purpose of reducing the number of separate components in an assembly, often to streamline production or enhance user convenience.

Take, for instance, electric car charging stations, where safety is paramount due to the high voltages involved. Loose hardware poses a significant risk of causing short circuits, potentially leading to fire hazards. To mitigate this risk, a straightforward solution involves employing screws with threaded ends wider than the shaft.

These screws are securely held within the charging station's cover plate by deforming the panel around the insertion point. As a result, service technicians can assemble the station without the concern of inadvertently dropping hardware, ensuring both safety and efficiency.

product Features

One of the features that lends to the wide variety of captivated screw combinations is how the screw or its retainer is attached to a panel or PCB. They regularly utilize surface mount technology (SMT), broaching, and self-clinching. More unique methods include flare-mounting with a floating option, which deforms the retainer to accommodate attachment to materials that can’t easily be clinched or broached.

Shoulder on retainer provides positive stop during installation.

Available in self-clinching, flaring, or floating mounting styles.

Available with knurled or un-knurled metal cap, black metal cap, or a custom color plastic cap.
