What are metric sockets used for?

What are metric sockets used for?

Metric sockets: Ideal for working on imported vehicles, metric sockets’ sizes are measured in millimeters. The most commonly used types are 8 mm, 10 mm and 14 mm sockets.

What is the difference between metric and standard wrenches?

The standard wrench uses the imperial system, and its units are in inches and incorporate fractions. On the other hand, the metric wrench uses the international system of units, and the measurements are in millimeters. Also, the numbers are whole, making interpretation an effortless process.

Is metric better than SAE?

Metric Measurements Metric is the preferred fastener measurement throughout the world. More exact than fractions of an inch, metric measurements–based on millimeters–are a precise representation of the diameter of the head of the fastener. Imported cars have used metric bolts for more than 30 years.

Are metric and imperial sockets interchangeable?

Metric sockets use imperial-sized drivers and the drive dimensions follow in US sizes, such as 1/4″, 3/8″, 1/2″, ¾. This means you can use the sockets whether it’s metric or SAE. Logically, smaller sockets would use smaller drive sizes, and larger sockets use larger drive sizes.

How do I know what socket to use?

Look through the table’s decimal column and select the first decimal larger than your caliper reading. Select the corresponding fraction. The website Sizes has a table showing Imperial (American) socket sizes. If the fraction is listed, it’s the size of your nut and required socket.

How do you know when to use metric or standard?

Depending on the context, “standard” often refers to U.S. fasteners. This typically means we’re talking about measuring units in inches, whereas metric is exactly that: measurements based on metric units, such as millimeters. Keep in mind, however, the U.S. is now producing fasteners using the metric system.

Do cars use metric or SAE?

Today, most of the domestic cars prefer using Metric bolts over the SAE inch sized bolts. Your new car must be a joint of Metric bolts and not the standard SAE bolts.

How can you tell if a bolt is metric or imperial?

Most bolts come in pretty uniform lengths; and this is a good way to determine if the bolt is metric or standard. Measure the bolt length (not including the cap), and see if it’s closer to a fraction of an inch, or a nice and round millimeter length that ends in 5 or 0.

Are metric and standard bolts interchangeable?

For standard bolts, head size is measured in inches or fractions of inches; however, metric bolt head sizes are measured in millimeters, which can cause confusion if engineers attempt to apply metric bolts to standard systems, and vice versa.

What does AF mean in sockets?

The term width across flats (AF) is used for the following forms: 2-socket = round material with two surfaces. 4-socket = profile square section. 6-socket, 8-square = regular polygons.

What’s between a 6mm and 7mm socket?

Metric Socket Sizes Chart

Do cars use metric or standard?

American cars are assembled with nuts and bolts that use standard measurements while foreign cars almost exclusively use metric measurements.

How can you tell the difference between imperial and metric threads?

Metric threads are measured by their pitch. That is the distance from the crest of one thread to the crest of the next measured in millimetres. The pitch of a metric thread can be checked by direct measurement with a metric rule. Imperial threads have their pitch measured indirectly as a given number of teeth per inch.

When did Ford switch to metric?

The Metric Conversion Act of 1975 is an Act of Congress that U.S. President Gerald Ford signed into law on December 23, 1975….Metric Conversion Act.

Does Ford use metric or standard bolts?

With a few exceptions of really old carryover parts (like the 8.8 rear axle in a Crown Vic), Fords and all manufacturers are metric and have been for quite some time. Even my 80’s Dodges are metric except for body fasteners and plumbing.
