Sealing Binding Barrels and Screws

Sealed with PVC foam under the head to prevent leaks and keep contaminants out. Barrels and screws have a low-profile head with a Torx drive. Screws have a knurled shoulder that resists rotation and adhesive on the threads to resist loosening. They're also known as Camtainer fasteners. A zinc plating provides corrosion resistance in wet environments. Barrel length is measured from under the head; screw length is measured from under the shoulder.
