You can identify an M6 screw by measuring the diameter with a ruler. It’ll be 6 mm, or slightly more than 7/32 inches (0.228″).
Are M6 and 1/4 20 the same?
I took the OP to mean that M6 fitted but was loose. This rules out 0BA which apart from the included thread angle is virtually identical, thus 1/4 BSF which has a similar pitch and slightly greater diameter. 1/4 20 tpi is either 1/4 Whitworth or 1/4 UNC, they are interchangeable for most purposes.
What size is a M6?
6 mm
M6 refers to a metric 6 mm screw. The outside diameter of the threads is 6 mm. The standard metric rack screw is actually an M6 x 0.1 mm. The number 0.1 mm refers to 0.1 threads per millimeter.
What is M6 equal to?

What is M6 size bolt?
6mm
M6 refers to a metric 6mm screw. The outside diameter of the threads is 6mm. The standard metric rack screw is actually an M6 x 1mm. The number “1mm” refers to 1 threads per millimeter.
Is M6 smaller than 1 4?
6mm equal to 0.2362 inches. Your 6mm spinner will “work” on a 1/4″ shaft, but you may have to ream out the hole a little to get it to slide on easily.
Are M6 and 1/4 28 the same?
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.

| M6-1.0 | 1/4-28 (Larger) |
| M7-1.0 | 1/4-28 (Smaller) |
| M8-1.25 | 5/16-18 (Smaller) |
| M10-1.5 | 3/8-16 (Smaller) |
Is M6 the same as #6?
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.

What size is M6 nut?
The situation on is almost as complex with metric nuts which come in a wide variety of types (full, thin, nyloc, castellated…..) and 5 strength grades as well as the same range of sizes.

How do you read thread pitch?
Thread pitch refers to the distance between threads and is expressed in millimeters. This measurement is taken along the length of the fastener. For example, if the distance between two threads is 1.6mm, this means the thread pitch is 1.6.

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.
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.
