    Stock up on our go-to internal retaining rings in a range of sizes. Squeeze with retaining ring pliers and release into a groove inside a bore or housing.
    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.
    Zinc-Yellow-Chromate-Plated Carbon Steel—These rings are strong with good wear resistance. They provide some corrosion resistance, but not as much as stainless steel rings.
    15-7 PH Stainless Steel—Combine strength with corrosion resistance. While harder than most stainless steel rings, these will dent and scratch easier than carbon steel ones.

    Image of Product. Front orientation. Retaining Rings. Spiral External and Internal Retaining Rings Assortment.
    Wind spiral retaining rings of many sizes into grooves. These are coiled, so no tools are required and they won't fly away during installation. Insert one end into the groove, then wind the rest of the ring into place.

    18-8 Stainless Steel—The choice for wet and outdoor environments. These rings resist rust, but they aren't as strong as carbon steel.
