Types of sockets

There are a wide variety of sockets in varying shapes sizes and depths, to help understand these a little better Cromwell has taken the liberty of showcasing a few of the most common types.

• Hex drive/socket - A drive or socket with six sides resembling a hexagon when viewed straight on.

• Double hex driver/socket - A driver or socket resembling two hexagons overlaying each other. Features twelve sides.

• Torx socket- A socket that features a 6-pointed star shape.

• Driver head/bit - A type of socket head that acts much like a screwdriver or Allen key.

• Deep sockets - Designed for fasteners that are hard to reach, these sockets come in a range of depths to suit the application.

Considerations when choosing a socket set

• Drive shape - Most common type of drive shapes are square and hex drive. Selecting the right socket shape for the drive will enable the socket to connect to wrench.

• Drive size - Much with drive shape this will determine whether the socket fits or not. Common sizes include 1/4-inch drive, 1/2-inch drive and 3/8-inch drives.

• Socket type - Sockets commonly come in square, hex, torx and double hex types, suitable for a variety of fastener types. Selecting the right type of socket type for the fastener ensure that you will be able to complete the job without delay.

• Socket size - Sockets come in various sizes with both metric and imperial measurements available for every size of fastener.

• Socket depth - Deep sockets allow to reach fasteners that are fixed in position where the bolt protrudes beyond the reach of a standard socket.

• Accessibility - Is the work environment confined or open? Is your range of motion going to be impaired by objects in the immediate environment? Flex head attachments and extension bars give you more reach. If you're going to be working in varied environments selecting a socket set with these options might be right for you.
