Screw type chain tool / link extractor - CT-3.3 - from Park Tool USA

Screw type chain tool - CT-3.3

A tremendous amount of force is needed to remove chain pins.

Note: for wide chains (3/16 and 1/8 in. like those used on BMX bikes) use the CT-7 chain tool.

The Park Tool screw type chain tool is made from investment cast steel - whatever that is!

Along with superior strength and durability, the CT-3.3 features a handy "loosening shelf" to remedy stiff links after reassembly.

The fine thread and comfortable size enable easy removal of even the toughest chain pins.

Like all Park Tool chain tools, it's easy to use and built to last.
