Press these nuts into the backside of a panel in applications where you have access to both sides of the panel. Install with an arbor press or similar pressure tool. A quarter-turn locks and releases access panels, doors, and covers. The screw is held to the outer panel by a retainer. An installation tool (sold separately) is required to install the retainer. Nuts and screws have a zinc plating that provides corrosion resistance in wet environments. Length is measured from under the screw head.

The nut clips onto the edge of a thin panel, allowing you to mount the screw near edges. A quarter-turn locks and releases access panels, doors, and covers. The screw is held to the outer panel by a retainer. Length is measured from under the screw head.

Press these nuts into a closed-end hole or thick panel in applications where the back of the panel is inaccessible. A quarter-turn locks and releases access panels, doors, and covers. The screw is held to the outer panel by a retainer. An installation tool (sold separately) is required to install the retainer. Nuts and screws have a zinc plating to resist corrosion in wet environments. Length is measured from under the screw head.
