Zinc-Plated Carbon Steel—These pins withstand occasional exposure to moisture. However, since friction from moving parts can wear away the finish, they're not ideal for wet environments. While not nearly as corrosion resistant as stainless steel, they are stronger and won’t deform under stress.
Loop Closure with Easy-Release Tab—Grip the tab to open and close with less effort than other wire-retainer clevis pins. The tab sticks out from these pins, so they might catch if space is tight.
