Hex Drive Binding Barrels and Screws
Stainless Steel
Black-Oxide Stainless Steel
Made from 18-8 stainless steel, these binding barrels and screws are chemical resistant and may be mildly magnetic. Barrel length and screw length are measured from under the head.
Black-oxide 18-8 stainless steel binding barrels and screws have a matte-black finish that matches dark surfaces and reduces glare.
