These screws have a head height about one-third the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines.

Install these rounded head screws through a hole and thread on a retainer to keep secure—no special tools are required.

The base flares out during installation, creating a backside flange in hard materials and near edges in panels up to 0.312" thick. Install with a flare-in installation tool and an arbor press.

Install in soft material such as aluminum and low-carbon steel at least 0.036" thick with an arbor press or similar pressure tool.

Push the plunger to secure and pull to release for quick access.

Press these rounded head 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.

Press these wing head nuts into the backside of a panel in applications where you have access to both sides of the panel. A quarter-turn locks and releases access panels, doors, and covers.

These wing-head screws have a clip-on nut that allows you to mount them near the edge of a thin panel. Use them to lock and release access panels, doors, and covers with a quarter-turn.

These rounded head screws have a nut that 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.
