Frequently Asked Questions

What is a bent nose external stop ring plier used for?

These pliers are specifically designed to install and remove external retaining rings, also known as external circlips or stop rings. The bent nose provides angled access to recessed clips, making it easier to work in confined spaces commonly found in marine equipment.

What is the difference between external and internal retaining ring pliers?

External pliers have tips that point inward and are used for rings that contract around a shaft, while internal pliers have tips that point outward to expand rings inside a bore. This product is for external rings, ensuring proper fit and safe operation.

Are these pliers suitable for saltwater environments?

Yes, the pliers are made from chrome vanadium steel with a corrosion-resistant finish, making them suitable for marine applications. However, as with all hand tools, rinse with fresh water and dry after exposure to saltwater to maximize service life.

What size of retaining rings can these pliers handle?

They are designed to handle external retaining rings with diameters from 10 mm to 60 mm. The fine tips fit most standard ring holes, providing a secure grip for controlled installation and removal.
