Four-Arm Extended-Tip Thumb Screws
Also known as dog- and pilot-point thumb screws, insert the point into a drilled hole or slot to hold items in place. Arms provide a flat surface to push your fingers against. A black-oxide finish on the threads provides corrosion resistance in dry environments. Length is measured from under the collar.
Aluminum heads are lightweight and corrosion resistant in wet environments.

Press-Fit Captive Panel Screws
Install in soft material such as aluminum and low-carbon steel at least 0.036" thick 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.
Zinc-plated steel bodies resist corrosion in wet environments.

Snap-In Captive Panel Screws
Powder-Coated
Aluminum Head
Snap these screws into panels up to 0.125" thick—no tools are required for installation. Screws have a built-in retainer and 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.
Screws with black powder-coated heads blend in with dark surfaces and aren’t reflective. They’re often used in dashboards, cockpits, or military equipment where glare is a concern.

Flare-In Captive Panel Screws
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. They require a 90° flared hole. 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.
Aluminum bodies resist corrosion in wet environments and are nonmagnetic.
