Low profile, matching head on both the bolt and screw allow for a nice clean look. Zinc plated steel is much stronger than common aluminum binder posts. Each barrel bolt assembly consists of one bolt and one screw. Binding capacity is determined by length of barrel bolt used. Otherwise known as Sex Bolts or Chicago Screws.
