Circlip pliers for internal and external retaining rings

Circlip pliers, also called snap-ring or retaining-ring pliers, engage the small holes in a circlip so the ring can be compressed or expanded and seated correctly. Internal circlips sit in a bore; external circlips sit on a shaft. The two jobs need opposite jaw action, so internal and external pliers are not interchangeable.

Straight tips suit open, easily reached positions. Bent 90-degree tips reach rings that sit close to a shoulder or inside a recess. Tip diameter, jaw length and overall reach have to match both the ring size and the clearance around it.

What to confirm before ordering circlip pliers

• Ring type: internal for bores or external for shafts. This decides the jaw action.
• Ring size and hole diameter: the tip diameter has to fit the ring holes without play.
• Tip shape: straight, or bent 90 degrees for recessed and shoulder-adjacent rings.
• Reach: plier length and jaw depth against the space actually available around the ring.
• Standard: circlip pliers are commonly specified to DIN 5254 for external rings and DIN 5256 for internal rings, or to ASME B107.19. State the standard you need so it can be confirmed.
• Order details: quantity, packaging and delivery destination.
