Stainless Steel Low-Profile Binding Barrels and Screws
Made from stainless steel, these binding barrels and screws are chemical resistant and may be mildly magnetic. A thin head provides a nearly flush finish with the material surface. Barrel length and screw length are measured from under the head.
All 18-8 stainless steel barrels and screws have good chemical resistance. Black-oxide 18-8 stainless steel barrels and screws have a matte-black finish.
316 stainless steel barrels and screws have excellent chemical resistance and can be used in saltwater environments.
Open-end barrels are tapped through the head to provide more thread engagement when fastening thin materials.
