What does 8.8 mean on a bolt?
In the case of a 8.8 grade bolt the first figure signifies that the Tensile Strength is at least 800MPa. The second figure signifies that the fastener will begin to yield at 80% of the Ultimate Tensile Strength, i.e. at least 640MPa.
What size is a M15 bolt?
M15 x 150mm
Metric Bolt, Size: M15 x 150mm (Din 931) 5 pcs.
What is the difference between M10 and M12?
The only difference between the M10 and M12 is the external appearance.
What does M12 mean?
Those are metric screw dimensions. M10 means a 10 millimeter outer diameter for the bolt or whatever piece it is; M12 means 12 millimeters. The part after the ‘x’ is the pitch — how many mm a thread is wide. To figure out which you have, you can measure the existing part with calipers and a thread gauge.
What size thread is a 10mm bolt?
Metric Shoulder Bolt Dimensions
| Shoulder Diameter (A) | Thread (C) | Thread Length (D) |

| 16mm | 12mm x 1.75 | 18.4mm |
What size nut fits a 10mm bolt?
A 17mm spanner therefore fits a nut 17mm across its flats and this is normally a nut to fit a 10mm diameter bolt (M10).
What size bolt has a 22mm head?

How can you tell if a bolt is metric or standard?
How long is that bolt? Most bolts come in pretty uniform lengths; and this is a good way to determine if the bolt is metric or standard. Measure the bolt length (not including the cap), and see if it’s closer to a fraction of an inch, or a nice and round millimeter length that ends in 5 or 0.
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.
How do I know if I have a M10 bolt?
If the size is M10 x 25, that would mean that the diameter is 10 mm.
M10-1.0 x 20
- 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.
Is M8 same as 8mm?
M8 is not exactly 8mm but it is sufficient from a non-engineering point of view as long as the thread pitch is correct. Luckily, most commonly available metric bolts have the same pitch. Regarding tolerance for common uses it can also often be ignored.
Which is bigger M6 or M8?
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) |
Are M8 and 5/16 the same?
Well, quick answer is no. They are not the same and they are not interchangeable, although they can work under certain circumstances. The most important part is understanding the meaning of M8 and 5/16 to refer to the size of a metric screw or bolt, so then we can see why they aren’t the same thing!
What’s the difference between 4.6 and 8.8 bolts?
Category 4.6/S refers to commercial bolts of Property Class 4.6 conforming to AS 1111.1 tightened using a standard wrench to a ‘snug-tight’ condition. Category 8.8/S refers to any bolt of Property Class 8.8, tightened using a standard wrench to a ‘snug- tight’ condition in the same way as for category 4.6/S.
