What is a half inch drive socket?

What are 1/2 drive sockets used for?

1/2 inch – 1/2″ sockets are generally used for nuts and bolts from around 10mm and up. A 1/2″ drive socket can apply enough force to undo all nuts on a car. There are also 3/4″ and 1″ ratchets but these are used on trucks, tanks and industrial machinery.

What does drive size mean for sockets?

The drive socket size is a measurement of the distance between the flat sides of the square recess. The drive socket size must match the drive square size of your turning tool for the socket to fit correctly. For example, a 1/4″ drive or 1/4″ square drive will attach to a turning tool that has a 1/4″ drive square.

What are the different drive sockets?

Drive Sockets



There are 5 different sizes of ‘drive socket’ that are commonly used: 1/4″, 3/8″, 1/2″, 3/4″ and 1″. The smaller the drive is, the smaller the head is likely to be as well.

What are the 3 common drive sizes for sockets and ratchets?

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.

Do I need a 1/2 drive socket?

Small, ¼-inch drive sockets can sometimes reach small nuts or bolts in tight spots more easily. Large, ½-inch drive sockets can handle more torque and are ideal for larger fasteners that require a longer ratchet or breaker bar to loosen or fully tighten.

How do you tell what size drive my ratchet is?

Drive Hole indicates the size of the drive hole (also referred to as the “driver hole” or “square hole”), which determines the torque size of the driver tool you’ll need. For example, you’d use a ½-inch drive socket with a ½-inch drive ratchet. L indicates the overall socket length.

What are the four socket drive sizes?

These drive fittings come in four common sizes: 1⁄4 inch, 3⁄8 inch, 1⁄2 inch, and 3⁄4 inch (referred to as “drives”, as in ” 3⁄8 drive”).

What are the 4 different types of sockets?

However, some of the commonest options you would find are 36mm sockets and 10mm sockets. Considering the standard sockets, you can find four common types, and they include 3/4 –inch, ½-inch, 3/8-inch, and ¼-inch sockets. Most of these options mentioned above come with bits that would fit Torx screws.

How do I know what size socket I have?

It’s important to note that socket sizes are actually given in two measurements, namely: The size of the drive socket (the part that attaches to the socket wrench). These are always given in imperial measurements, and will usually be either 1/4″, 3/8″, 1/2″, 3/4″ or 1″.

What are the socket sizes in order?

Six Point Standard Sockets (3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, 1)

Can I use impact sockets with a ratchet?

You can absolutely use an impact socket on a hand tool ratchet, a breaker bar or a torque wrench without damaging the tool or placing yourself at risk. New impact sockets are designed with a shoulder that is stepped down to a parallel neck.

Does drive size matter?

Hard Drive Processing



The size of the hard drive doesn’t matter, but a faster hard drive takes less time to send data to the processor. Additionally, the hard drive can be used to hold a page file, also known as virtual memory, that acts as an extension of the computer’s main memory, the RAM.

Are deep sockets better?

Deep sockets are longer in length therefore can reach lug nuts and bolts that standard sockets are unable to reach. Deep impact sockets are suitable for a wider range of applications. In most cases, they can be used in place of a standard sockets.

How do I know what size socket to use?

How to Determine the Right Size Socket for a Nut

  1. Turn on the digital caliper and set it to read in inches, not millimeters. …
  2. Close the caliper jaws until each jaw rests on one flat side of the nut on opposite sides.
  3. Check the caliper display. …
  4. Turn on the digital caliper and set it to read in millimeters, not inches.

Can I use a 12-point socket on a 6 point nut?

A 12-point end is a double-hexagon (sometimes called “double-hex”)—it has 12 points, or vertices, evenly spaced at 30 degree increments around a circle. This geometry will also fit on a 6-point fastener.

What does drive size mean for screws?

Drive style—or drive recess as it is called—refers to the kind of tool you use to install (or remove) the screw. Of the many that exist, the most common are: slotted, Phillips, combination (both slotted and Phillips), hex, hex socket, square, Torx® and spanner.

Are 6 or 12-point sockets better?

Answer: It’s true that 12-point sockets are fine for most lightweight repairs, but heavy wrenching calls for a six-point socket. A six-point socket is much less likely to slip off a stubborn fastener or round over the corners. Here’s why: (1) Six-point sockets have thicker walls, so they’re less likely to flew.

Why are impact sockets black?

Impact sockets are typically black. This is because the surface is carbonized in order for it to harden. Ensuring that the surface is hard allows the sockets to absorb sudden torque changes i.e. “impact” a lot better.

When would you use a 6 point socket?

6 point sockets are used in applications using hexagonal fasteners. This is obvious since the 6-point socket will not fit on any other shape bolts. They are also ideal for situations that require a large amount of force due to their greater wear resistance. Typical uses include automotive applications and outdoor work.
