What size is a M16 bolt?
What size is a M16 bolt?
Metric bolts are made fractionally under their stated size, for instance an M16 bolt will have a shank diameter of typically 15.97mm. This means that a 16mm bolt will fit through a 16mm hole but to allow for misalignment between parts it is common practice to drill bolt holes slightly larger.
What is M16 bolt inches?
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 |
|---|---|
| M10-1.5 | 3/8-16 (Smaller) |
| M12-1.75 | 1/2-13 (Larger) |
| M14-2.0 | 9/16-12 (Larger) |
| M16-2.0 | 5/8-11 (Smaller) |
What does M mean in bolt sizes?
metric thread
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 size head does a M16 bolt have?
Dimensions for DIN931 Hex Head Bolt
| Diameter (d) | Pitch | Head Depth (k) |
|---|---|---|
| M14 | 2mm | 8.8mm |
| M16 | 2mm | 10mm |
| M18 | 2.5mm | 11.5mm |
| M20 | 2.5mm | 12.5mm |
What is the pitch of a M16 thread?
2.0
Metric Thread Pitch and Tapping Sizes
| Size | Pitch (mm) | Tapping Diameter (mm) |
|---|---|---|
| M8 | 1.25 | 6.8 |
| M10 | 1.5 | 8.5 |
| M12 | 1.75 | 10.2 |
| M16 | 2.0 | 14.0 |
What does m8x1 25 mean?
For metric fasteners, you will see a M8 x 1.25 or an M8 x 1. For thread pitch, the distance between two points is the second number meaning the higher the number the fewer threads there are. This means the M8 x 1.25 is the coarse threading and the M8 x 1 is the fine thread.
What does M mean on a bolt head?
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 do bolt size numbers mean?
The number 1 or number larger than one, or number one or number larger than one followed by a fraction, is the diameter of the shaft. 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. Same as for smaller parts.
How is a bolt 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.
What is nominal diameter of bolt?
The size most commonly associated with screw threads is the nominal diameter. Nominal diameter is a 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.
