    Tight-Clearance Inverted External Retaining Rings

    Image of Product. Front orientation. Retaining Rings. Tight-Clearance Inverted External Retaining Rings.
    The lugs on these rings point inward, so they won't snag on other parts and have better clearance than standard external rings. Shaped in the most common style, they are tapered so the thickest section is opposite their opening for a secure 360-degree hold. Open with retaining ring pliers, pass over the end of a shaft, then release them to spring into a groove.
    Ring ID is measured with the ring uninstalled.
    Phosphate-Coated Carbon Steel—The most popular choice, these are strong and wear resistant. Their finish adds some corrosion resistance, but only to minimal dampness.
