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 an M6 bolt in standard?
6mm
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 and 1/4 the same?
The size of a metric screw or bolt is specified as diameter, pitch and length, in millimeters (millimeters is abbreviated “mm”).
Table 3.
| Metric | Closest Inch |
|---|---|
| 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) |
What is an M6 screw size in mm?
ISO Metric Machine Screw Thread Dimensions
| Thread Size | Nominal Diameter (mm) | Thread Pitch (mm) |
|---|---|---|
| M4 | 4.0 | 0.70 |
| M4.5 | 4.5 | 0.75 |
| M5 | 5.0 | 0.80 |
| M6 | 6.0 | 1.00 |
What is the pitch diameter?
Pitch diameter is the distance from the pitchline to the corresponding pitchline located 180 degrees around. All threads have a pitch diameter whether they are a straight or tapered thread. However, some threads’ pitch diameters are actually measured via their crest diameter (diameter from crest to crest) instead.
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 size head does a M6 bolt have?
SOCKET HEAD CAP SCREW – METRIC
| Size | Diameter | Head Diameter |
|---|---|---|
| M3-0.5 | 3.00 | 5.50 |
| M4-0.7 | 4.00 | 7.00 |
| M5-0.8 | 5.00 | 8.50 |
| M6-1.0 | 6.00 | 10.00 |
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.
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.
Which is bigger 6mm or 1/4 inch?
6mm = almost 1/4 inch. 7mm = almost 9/32 inch (= a bit over 1/4 inch) 8mm = 5/16 inch. 9mm = almost 3/8 inch.
What is M in bolt size?
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.
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 diameter is M6?

|---|---|---|
| M4 | 4.0 | 3.545 |
| M4.5 | 4.5 | 4.013 |
| M5 | 5.0 | 4.480 |
| M6 | 6.0 | 5.350 |
What size is M6 hole?

| Nominal size | Pitch | Percentage of thread engagement hole diameter (mm) |
|---|---|---|
| M5.5 | 0.5 | 5.07 |
| M6 | 1 | 5.13 |
| 0.75 | 5.35 | |
| 0.5 | 5.57 |
What does m3 0.5 mean?
Full Member. 0.5 is the pitch, which is standard pitch for m3.
What is circular pitch?
Pitch measurements
Circular Circular pitch is the distance from a point on one tooth to the corresponding point on the next tooth measured along the pitch circle as shown in Figure 57.32. Its value is equal to the circumference of the pitch circle divided by the number of teeth in the gear.
How do you find pitch diameter?
To calculate the pitch diameter, one must imagine a cylinder whose diameter exists at the point where the thread groove width and the thread crest width are both equal to one another and equal to half the nominal pitch of the thread. The diameter of this imagined cylinder is the pitch diameter.
What roof pitch is 30 degrees?
7/12
A 30° roof pitch is roughly the same as a 7/12 roof pitch. To convert from degrees to the American ratio: Find the tangent of the angle, tan(angle). This gives you the pitch of the roof.
What diameter is a #6 screw?
American Screw Sizes
| THREAD DIAMETER | ||
|---|---|---|
| Size | Nearest Fraction | Millimeter |
| #4 | 7/64 | 2.8 |
| #5 | 1/8 | 3.1 |
| #6 | 9/64 | 3.3 |
What is the thread pitch?
• The thread pitch is the distance between corresponding points on adjacent threads. Measurements must be taken parallel to the thread axis. • The major diameter or outside diameter is the diameter over the crests of the thread, measured at right angles to the thread axis.
