United Rentals offers a selection of ratchets for tightening and loosening nuts and bolts. Ratchets are tools similar to wrenches, except they are designed to move in one direction while preventing motion in another. Air ratchet wrenches are pneumatic, air-driven tools that promote ease and efficiency. Air ratchets offer a practical and simple solution, as their design allows for easy use in smaller spaces, where fasteners are often found. Our selection includes 3/8 inch and ½ inch ratchets, which are often used in mechanical applications, like tightening nuts and bolts in the automotive, agricultural and engineering industries. Learn more about ratchets in our FAQ section below.
A ratchet is a tool that is designed to tighten and loosen nuts and bolts more efficiently than traditional hand tools. Ratchets are designed to turn in one direction, tightening or loosening bolts at high torque. Need more help? Contact one of our equipment experts for further guidance.
Ratchets are designed to move in one direction at a time, but employ a switch when you need to change direction. To loosen nuts or bolts, turn your ratchet counterclockwise. To tighten, turn your ratchet clockwise.
Ratchets and socket wrenches are similar in look and operation, but have a few key differences. Ratchets are much longer and smaller, allowing for high-torque use in small spaces. Socket wrenches are bulkier and are designed to move or turn nuts and bolts, while a ratchet is designed to tighten or loosen them. Additionally, ratchets have a lower gear ratio for higher torque with less force.
