Zinc-plated steel extensions are corrosion resistant in wet environments. They are also magnetic.
All 18-8 stainless steel extensions have good chemical and corrosion resistance. They may be mildly magnetic. Black-oxide 18-8 stainless steel extensions have a matte-black finish.
316 stainless steel extensions have excellent chemical and corrosion resistance, can be used in saltwater environments, and may be mildly magnetic.
All aluminum extensions are lightweight, corrosion resistant in wet environments, electrically conductive, and nonmagnetic. Black-oxide aluminum extensions have a matte-black finish.
Brass extensions are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. They’re also friction resistant, so you can make smooth adjustments when they’re used as pivot points.

Brass Low-Profile Binding Barrels and Screws
These brass binding barrels and screws are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. A thin head 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.

Brass Binding Barrels and Screws for Door Hardware
Brass binding barrels and screws are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. Use them to anchor door closers, kickplates, and other architectural hardware. The barrel head is smooth with no drive to be tampered with on the outside of your door, and the screw has a flat head that sits flush with the surface for a finished look. The screw protrudes from the barrel to leave room for hardware. Install in a hole with a diameter equal to the barrel diameter. Barrel length and screw length are measured from under the head.
