Take the diameter of the bolt, and multiply by 1.5. This calculation and conversion factor is valid for either metric or standard bolt sizes. The resulting number will be the size of the wrench you need to adjust the bolt properly. For example, If your bolt measures .
What size socket is my nut?
How to Determine the Right Size Socket for a Nut Turn on the digital caliper and set it to read in inches, not millimeters. Close the caliper jaws until each jaw rests on one flat side of the nut on opposite sides. Check the caliper display. Turn on the digital caliper and set it to read in millimeters, not inches.
How do I know what size nut I need for a bolt?
To measure the diameter of screws and bolts, you measure the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.

How do I know what size nut to buy?
If the nut is metric, count the number of lines on the tape measure to find the measurement. If you count 9 lines, the size is a 9-mm (millimeter) nut. If the nut is US standard, count the smallest lines on the tape measure in sixteenths. Add the sixteenths together to find the size.
Is the diameter of a bolt the same as the wrench size?
When ordering a bolt you will need to determine. bolt diameter, thread pitch, and bolt length. Technician A says that the diameter of a bolt is the same as the wrench size used to remove or install the fastener.
How do you measure a wrench bolt?
Tip Insert the shank of the bolt into the holes in a bolt-sizing gauge. Locate the printed bolt size to the side of the correct hole on the gauge (for example, 1/2, 3/4 or in mm for metric bolts). Locate the socket head in the socket set that has this size printed on its side.

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

What does M12 mean?
The first half (M12), is the size measurement (metric) taken across the outside diameter of the thread (which in this case is 12mm). The second half is the thread pitch, which is the measurement of threads/inch (which in this case is 1.75).
What does M12 nut mean?
This example illustrates how a coarse threaded screw may appear… M12 x 25 = 12 mm diameter, coarse thread is assumed (1.75 mm), 25 mm long. M12 is a matching coarse threaded nut. (To avoid confusion, we always include the thread pitch for both coarse and fine metric fasteners.).
How do wrench sizes work?
Spanner. The width across flats indicates the “size” of the spanner. It is imprinted on the spanners in millimeter (mm) values. Older British and current US spanners (wrenches) have inch sizes that are imprinted in intermediate sizes in fractions.
What are the sizes of sockets?
There are four common socket sizes: 1/4 inch (0.6 centimeters), 3/8 inch (0.9 centimeters), 1/2 inch (1.3 centimeters) and 3/4 inch (1.9 centimeters).
What sizes do adjustable wrenches come in?
Adjustable wrenches should be included in every professional toolbox in the following sizes: 6-inch, 8-inch, and 12-inch wrenches. These sizes are suitable for a variety of tasks.
What grade is a bolt with 3 markings?
Three radial lines will indicate an SAE grade 5 fastener, while six radial lines will indicate an SAE grade 8 fastener.
What is the easiest way to identify the TPI?
As the name suggests, TPI is measured by counting the number of thread peaks along a 1 inch length. The TPI measurement is then often affixed to the diameter of the thread to form a common imperial thread size, e.g. ‘1/4-20’, which would denote a ¼ inch diameter, and 20 threads per inch.
