What does M6 mean?
M6 threads are 6mm metric 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.
Is M6 smaller than 1 4?
The size of a metric screw or bolt is specified as diameter, pitch and length, in millimeters (millimeters is abbreviated “mm”).

How do you identify metric threads?
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.

What is a #6 screw?
A 6 gauge screw will have a head almost equal to 6 mm wide. Correlation between diameter (metric in mm), gauge(imperial) and head size is complicated.
What does a 1/4 20 screw mean?
The fraction is the diameter of the shaft, in fraction of an inch. The number following the hyphen is the number of threads per inch, that is, the number of threads on the shaft itself, per inch of shaft length. 1/4-20: One quarter inch shaft diameter, 20 threads per inch.

How are Allen bolts sized?
Size refers to nominal diameter of the bolt while length is just that—how long the bolt is. 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. From 3/8″ to 1″, lengths are in 1/8″ increments.
How are Allen bolt sizes measured?
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.
