What Are The Most Common Metric Wrench Sizes?

What are 8 point sockets for?

The 8 point sockets are designed for quick engagement on 4 point fasteners.

They have a high polished chrome finish.

The size of the sockets range from 3/8 to 1 1/4-Inch..

What is better 6 point or 12 point?

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.

How do you tell if a bolt is SAE or metric?

Metric and SAE fasteners are measured differently and with different vocabulary. SAE nuts, bolts and screws are measured by their thread count, or TPI (threads per inch) and their length. Metric fasteners are measured by length and pitch, or the distance between threads.

Why do 12 point sockets exist?

12 Point Sockets. The additional points make these sockets easier to connect with the heads of fasteners. This is ideal if you are trying to work on a fastener that is hard to see or you cannot see at all. 12 point sockets are also great for use in tight spaces as they allow you to connect to a fastener at more angles.

What does m8 1.25 mean?

For metric fasteners, you will see a M8 x 1.25 or an M8 x 1. For thread pitch, the distance between two points is the second number meaning the higher the number the fewer threads there are. This means the M8 x 1.25 is the coarse threading and the M8 x 1 is the fine thread.

Should I buy SAE or metric?

Some trucks used the metric system of fasteners while some cars used both metric and SAE fasteners. … If you are passionate about imported cars or just to prefer them to work on, then metric tools give you real pleasure. So, you don’t need to buy SAE tools to accomplish your most jobs.

Are 6 point sockets better?

For 6-point fasteners, a 6-point tool is your best choice. Matching up the points between the tool and fastener means that you will maximize the surface area of steel in contact, making the tool less likely to slip or fail.

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

Telling the difference between a metric and imperial bolt is easy. If the bolt has lines on the head its standard or imperial. If the bolt has numbers on the head then its metric. These markings indicate how strong the bolt is they call this tensile strength.

What is the difference between SAE and metric?

While the majority of bolt-type fasteners used in the United States conform to one or the other measurement scale, the difference between SAE and metric fasteners (and their corresponding sockets) is as profound as the difference between yards and meters: They are almost the same, but not quite.

Does Ford use SAE or metric?

Ford has a couple metric 12 point fasteners on their drive shafts as well. American cars haven’t been SAE in a long time. So what uses SAE?

What are standard bolt sizes?

Typically, machine bolt sizes range from 1/4″ to 1 1/4″ for square heads and 3/8″ to 1 3/4″ in diameter for hex heads, and lengths span from about 3/4″ to 18″ for square and 6 1/2″ to 24″ for hex heads. Measure length from under the head to the threaded end of the bolt.

What is the most common wrench size?

Most common are the 1/4-inch, 3/8-inch and ½-inch ratchet drivers, but ¾-inch and 1-inch sets are available for heavy-duty work.

What are the metric wrench sizes?

Metric Combination Wrenches (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19) Standard Flare Nut Wrenches (3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 7/8) Note: Each wrench may combine two sizes. Metric Flare Nut Wrenches (9, 10, 11, 12, 13, 14, 15, 17) Note: Each wrench may combine two sizes.

How do I know what size wrench to get?

Multiply the first number which is the bolt size in inches or millimeters, by 1.5 using a pocket calculator, if necessary. For example, for the numbers in Step 1, 1/2 x 1.5 = . 75 or 3/4, which is the wrench size needed for this standard-sized bolt.
