How do I know if my bolts are metric or standard?
For both metric and standard bolts, the head size is the distance across the flats. For standard bolts, the head size is measured in inches or fractions of an inch. For metric bolts, head size is measured in millimeters. However, metric bolt head size is measured in millimeters.
What are metric bolts used for?
Metric Bolts Metric bolts are bolts that are measured and classified according to the metric system that is used as a worldwide standard for measurement. Metric bolts are an essential component for any product or piece of equipment that must be compatible with parts from other continents such as Europe or Asia.
What size screw is M10?
M10-1.0 x 20 M = This designates the fastener is a metric size. 10 = The nominal diameter in millimeters. 1.0 = The thread pitch, or distance between threads, in millimeters.
Is M6 or M8 bigger?
The size of a metric screw or bolt is specified as diameter, pitch and length, in millimeters (millimeters is abbreviated “mm”). For nuts, size will appear as diameter and pitch….Table 3.
| Metric | Closest Inch |
|---|---|
| M6-1.0 | 1/4-28 (Larger) |
| M7-1.0 | 1/4-28 (Smaller) |

Is metric and SAE the same?
SAE sockets are sized in inches and fractions of inches. Metric and SAE wrenches have different systems of measurement. Metric sockets and wrenches use the metric measurement system. This is when millimeters are used to describe the size.
What is difference between metric and 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.
What is difference between SAE and metric?
SAE & Metric: What’s the Difference? SAE sockets are sized in inches and fractions of inches. Metric and SAE wrenches have different systems of measurement. Metric sockets and wrenches use the metric measurement system.
What is the difference between M10 and M12?
The size of a metric screw or bolt is specified as diameter, pitch and length, in millimeters (millimeters is abbreviated “mm”). For nuts, size will appear as diameter and pitch….Table 3.
| Metric | Closest Inch |
|---|---|
| M8-1.25 | 5/16-18 (Smaller) |
| M10-1.5 | 3/8-16 (Smaller) |
| M12-1.75 | 1/2-13 (Larger) |
| M14-2.0 | 9/16-12 (Larger) |
What size is 10mm bolt?
Metric Shoulder Bolt Dimensions
| Shoulder Diameter (A) | Thread (C) | Head Diameter (E) |
|---|---|---|
| 8mm | 6mm x 1.0 | 13mm |
| 10mm | 8mm x 1.25 | 16mm |
| 12mm | 10mm x 1.5 | 18mm |
| 16mm | 12mm x 1.75 | 24mm |
Is 5/16 or 8mm bigger?
8mm = 5/16 inch. 9mm = almost 3/8 inch. 10mm = just over 3/8 inch. 11mm = almost 7/16 inch.
What does M12 mean on a bolt?
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).
How do I know if my screws are imperial or metric?
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.
Can you use SAE on metric bolts?
Can you use Metric sockets on SAE fasteners or SAE Sockets on Metric Fasteners? Yes, you can use some sockets on both metric and SAE sizes. However, you need to be careful, as most times they are not exactly the same, and you can strip a bolt by using an SAE socket on a metric bolt and vice versa.
Why is metric better?
Metric is simply a better system of units than imperial In other words, it fits together very well and calculations are easy because it is decimal. This is a big advantage for use in the home, education, industry and science.
How can you tell the difference between metric and imperial bolts?
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.
How do I know if my nuts are metric?
The size of a metric screw or bolt is specified as diameter, pitch and length, in millimeters (millimeters is abbreviated “mm”). For nuts, size will appear as diameter and pitch. There is an exception though—if pitch isn’t specified, the fastener is coarse threaded. Consider this size…
