Internal retaining ring pliers compress internal snap rings or circlips. External retaining ring pliers spread external snap rings or circlips. Convertible models can be configured for either internal or external snap ring work, while dedicated four-piece and five-piece selections cover multiple common tasks.

  • Internal options are represented for rings from 40 mm to 100 mm inside diameter and for an 85–200 mm range stated by outside diameter.

  • Horseshoe washer and lock ring pliers spread soft iron horseshoe lock washers and tempered steel lock rings.
Access and fit

Compare pin size, jaw shape, and reach

Tip and jaw geometry affect how the pliers approach a compatible ring. Straight-jaw designs keep handles parallel to the shaft, while 90-degree designs keep handles perpendicular to the shaft. Curved long-nose internal pliers add reach for recessed or hard-to-reach locations.

  • Tapered pin options include 0.9 mm, 1.3 mm, 2.3 mm, 3.2 mm, 3/32-inch, and 1/16-inch tips.
