Product Overview
A ratchet wrench, also called a socket wrench, is a hand tool used to loosen and tighten fasteners. Fasteners include nuts and bolts that secure the ends of screws in buildings, furniture, and some electronic devices.
The body of a ratchet wrench is usually made of metal and consists of a long, narrow ratchet handle and a small hollow attachment. Sockets are designed to modify different sizes of hardware to fit the fasteners that tighten the wrenches. The ratchet wrench gets its name from the action of the ratchet that tightens and loosens the screw. This tool is used for building or repairing various types of objects such as car repairs and building construction. Used to change the wrench to fit different size fasteners.
Insert the square part of the socket into the square hole in the wrench handle so that the socket engages the ratchet. The bushing is held in a square hole called an actuator and has a mechanism called a ball detent or ball stopper that uses a spring-loaded ball to lock the bushing to the actuator.
The size of the drive hole in the ratchet wrench handle determines the size of socket it will hold. The ratchet wrench handle and socket must match the size of the drive it will be used with.
Features
• Available with different drive sizes — 1/4 inch, 1/2 inch and 3/8 inch — to operate different size sockets.
• Most operate with a geared drive; those with a higher tooth count let you operate the tool with a smaller swinging motion, which is useful when there's little room to move the handle.
• Gearless models operate with a roller bearing and require smaller movements to turn fasteners than a geared drive.
• Many have a lock that keeps the socket from falling off or sticking on the fastener; a quick-release button disengages the lock.
• Jointed or flexible-head ratchets (bottom image) allow you to adjust the angle of the handle to work in tight areas.

Metric and standard sizes.
Ratchet action on one end moves freely in one direction and engages the fastener in the other.
