How do you figure out what size bolts you need?
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.
What does M10 mean in bolt size?
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. 20 = The fastener’s length, in millimeters.
What are standard bolt sizes?
US Standard Thread Length for Bolts
| Bolt Diameter | Standard Thread Length (in.) * | |
|---|---|---|
| Bolts 6 inches and shorter | Bolts longer than 6 inches | |
| 1/4″ | 3/4″ | 1″ |
| 5/16″ | 7/8″ | 1-1/8″ |
| 3/8″ | 1″ | 1-1/4″ |
How do bolt sizes work?
The size of a metric bolt is specified using pitch, diameter, and length in millimeters. For example, in M8-1.0*20, the “M” means the Metric thread designation, the digit 8 refers to the Nominal diameter (in millimeters), 1.0 refers to the pitch, and 20 refers to the length.
Are M10 and 3/8 the same?
That said, they are very close, the 3/8″ bolt is about 0.019″ smaller and the pitch’s are very close so the 3/8 -16 bolt will thread in the 10mm x 1.5 but the 10 x 1.5 bolt will not fit the 3/8 but..
What are M bolt sizes?
Metric Bolt Sizes
- The letter ‘M’ indicates that this bolt uses a metric thread.
- The number ‘8’ refers to the nominal diameter of the bolt shaft in millimeters.
- The number 1.0 is the thread pitch of the bolt, which is the distance between threads, in millimeters.
- And the final figure, 20, is the length in millimeters.
Is bolt a size?
A bolt’s size is classified based on a number of dimensions, namely the bolt’s diameter, length of shank, thread pitch, grade, thread length and head size. Bolts can me specified in metric using millimeters, but the standard, internationally-recognized descriptions of bolt sizes are in inches.
What size is a M8 bolt?

| M6 | 6.5 | 5.0 mm |
| M8 | 9 | 6.75 mm |
| M10 | 11 | 8.5 mm |
Does bolt size matter?
Normally it will not matter whether the bolt head or the nut is torqued. This assumes that the bolt head and nut face are of the same diameter and the the contact surfaces are the same (giving the same coefficient of friction). If they are not then it does matter.

How are nuts and bolts measured and how are they measured?
How to Measure Nuts & Bolts. Bolts commonly use four types of measurement, while nuts use only two. Bolts are measured in length of shank, bolt head size, width of shank (the diameter of the threaded bolt body) and the thread pitch (the size of the thread). Nuts are measured by the width of the hex shape and by their thread pitch.
What’s the difference between a nut and a bolt?
(Nominal diameter is more of a label than a size. For example, a bolt and nut may be described as being ½” diameter. But neither the external threads of the bolt nor the internal threads of the nut are exactly .500 in diameter.
