About Thumb Screw and Binding Post Materials

Aluminum Low-Profile Binding Barrels and Screws
Made from aluminum, these binding barrels and screws are lightweight, corrosion resistant in wet environments, and nonmagnetic. A thin head provides a nearly flush finish with the material surface. Barrel length and screw length are measured from under the head.
Open-end barrels are tapped through the head to provide more thread engagement when fastening thin materials.
Black anodized binding barrels and screws have an attractive black finish.
