How are M bolt sizes measured?
Do not measure the head of the bolt, measure the threaded part, outside of the threads. If your bolt is metric, then the diameter is stated using the letter “M”. For example, if your bolt has a diameter of 4mm then it is called an ‘M4 bolt’ if your bolt is imperial then it will be measured in inches.
What size are the hex bolts?
Hex bolts range in size from 1/4″ to 4″ in diameter; 1/4″ to 1 1/2″ sizes are commonly available. Lengths range from 3/8″ to 24″; 1/2″ to 10″ is typical.
What does the M stand for on screws?
The standard metric rack screw is called M6 x 1. The ‘M’ means it’s metric. The ‘6’ is the outside diameter measured in millimeters, and the ‘1’ is the distance between adjacent threads, also in millimeters. Metric threads are used outside of the USA, and commonly in products by HP and other global entities.
How do you size a hex nut?
Place the end of a measuring tape on one of the flat sides of the nut’s outer perimeter. Stretch the tape measure across the nut’s diameter to the flat-side directly across from the one your pulling from. If the nut is metric, count the number of lines on the tape measure to find the measurement.

What is a hex size?
Hex nut size refers to its nominal thread diameter. Typically, sizes range from 1/4″ to about 2 1/2″. Size is specified in inches, usually fractional rather than decimal. Table 1 lists width across flats and across corners, and thickness.
What is the size of a metric bolt?
Metric bolts are referenced using “M” sizes, such as the M8 bolt size. 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.
What are the dimensions of a hex bolt?
Heavy Hex Bolt Dimensions Bolt Diameter D F F H 5/8 0.642 1-1/16 1.062 27/64 3/4 0.768 1-1/4 1.250 1/2 7/8 0.895 1-7/16 1.438 37/64 1 1.022 1-5/8 1.625 43/64
Are hex bolts and hex cap screws the same thing?
However, make sure you are comparing apples to apples, because “Hex Bolts” and “Hex cap screws” are different! Lightning Bolt has many people that contact us which interchange the names of hex cap screws and hex bolts as they are synonymous… they are not. Hex bolts are “less precise” and therefore cheaper than hex cap screws.
What does M8 20 mean on a bolt?
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. Sometimes, the pitch is omitted in the abbreviated format, such as M8-20, this means the bolt has a coarse thread.
