    SAE-LT Thread—SAE-LT threads are tapered but designed to be installed into a 1/4"-28 straight-thread UNF hole.
    Zinc-Plated Steel—Zinc-plated steel fittings have mild corrosion resistance.
    303 Stainless Steel—303 stainless steel fittings are more corrosion resistant than brass fittings and have good chemical resistance.
    Ball Check Valve—Fittings with a check valve prevent grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.

    Self-Tapping Grease Fittings for Unthreaded Holes

    To fit securely in unthreaded holes, these fittings cut threads as they’re installed. Use a hex wrench to install. Fittings can be driven in, but then are not pressure rated. They're zinc-plated steel for mild corrosion resistance. All have an integral check valve that prevents grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants. These fittings are also known as hydraulic grease fittings.
