Install through a hole and thread on a retainer (sold separately) to keep these screws secure—no special tools are required. Use an optional spring (sold separately) to provide even compression against panels. Screws, retainers, and springs are made from chemical-resistant 18-8 stainless steel and may be mildly magnetic. Length is measured from under the head.

Install through a hole and thread on a retainer (sold separately) to keep these screws secure—no special tools are required. Use an optional spring (sold separately) to provide even compression against panels. Screws, retainers, and optional springs are made from chemical-resistant 18-8 stainless steel and may be mildly magnetic. Length is measured from under the head.

These screws mount flush against the outer panel's surface for low-clearance applications. Install in soft material such as aluminum and low-carbon steel with an arbor press or similar pressure tool. Screws become a part of the panel when installed, so they won't fall out and get lost. They're often used with surface mount nuts.
For technical drawings and 3-D models, click on a part number.
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.

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.
Zinc-plated steel nuts and screws are corrosion resistant in wet environments. An installation tool (sold separately) is required to install the retainer.
Acetal plastic nuts and screws are chemical resistant and lightweight.
