Steel Low-Profile Binding Barrels and Screws
These binding barrels and screws have a thin head that 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-oxide steel barrels and screws have a dark surface color and are mildly corrosion resistant in dry environments.
Zinc-plated steel barrels and screws resist corrosion in wet environments.
