How to Use a Ratchet

Determine which ratchet size fits the job you are doing. The size of the drive tang determines what size socket to select. 

Ratchets come in three sizes: 

• A 1/4-inch ratchet is best for smaller sockets and precision work.
• The most versatile ratchet is the 3/8-inch size. This ratchet size can accommodate sockets of all sizes. It is big enough to apply a lot of force, but it can still fit into tight spaces.
• A 1/2-inch ratchet is for larger nuts and bolts.

Sockets come in multiple sizes and different depths. Use deeper sockets for long bolts and tight spaces. The size and length of the nut or bolt will determine the socket size. For example, a 1/4-inch nut will require a 1/4-inch socket. An adapter allows you to switch the drive tang size during any job to fit larger or smaller bolts.

Tip: Larger ratchet wrenches have the dual option for shallow and deep sockets. Shallow sockets are best for short bolts and nuts. Deeper ones are ideal for longer ones.

Once you have the appropriate size socket, it’s time to attach it to the ratchet handle. Align the bottom square hole of the socket with the drive tang. Push it to connect them. If the socket has a groove, notch or side hole, line it up with the ball bearing on the drive tang. Then, push or tap the socket down until you hear a snap as the ball bearing fits in the notch or groove. 

Tip: Sockets should be easy to swap out as you need different sizes, so choose a ratchet with a quick-release button on the ratchet head.

Before tightening or loosening a nut or bolt, check to make sure the socket is turning in the right direction.

• Hold the socket in one hand and use your other hand to move the ratchet handle left and right. It will only move in one direction.
• To loosen a nut or bolt, the socket handle should turn counterclockwise.
• To tighten a nut or bolt, the socket should turn clockwise.
• If the socket is not turning in the appropriate direction, turn the lever on the back of the ratchet to switch the direction.

Once you’ve checked the turning direction, align the socket with the nut, bolt or fastener. Slide it over as much of the hardware as possible until it’s secure. You may have to rotate the socket slightly for good contact. 

Once the socket is securely in place on the nut or bolt, turn the ratchet handle:

• Rotate the ratchet handle in the direction you wish to turn the fastener.
• When there is no more room to move the ratchet handle, rotate the handle back to the starting point.
• The ratchet mechanism will not turn the socket or fastener when the handle is rotated back to the starting point.
• Once the handle is back in the start position, rotate the handle in the other direction to continue turning the fastener.
• Repeat until the fastener is tightened or loosened as needed.
