What is the length of M12 bolt?
What is the length of M12 bolt?
Standard Thread Length for Bolts | Metric
| Bolt Diameter | 125mm and Shorter | Longer Than 125mm |
|---|---|---|
| M7 | 20 | 26 |
| M8 | 22 | 28 |
| M10 | 26 | 32 |
| M12 | 30 | 36 |
What does A325 bolt mean?
ASTM A325 is an ASTM International standard for heavy hex structural bolts, titled Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength. It defines mechanical properties for bolts that range from 1⁄2 to 11⁄2 inches (13 to 38 mm) in diameter.
How do you measure A325 bolt length?
The length of the bolt would need to be (3/8″ X 2) + 1 5/32″ = 1.90625″ rounding up on the size (increment by 1/4″ inch) would give us 3/4″ X 2″ A325 Structural Bolts.
What does M12 mean on a bolt?
The first half (M12), is the size measurement (metric) taken across the outside diameter of the thread (which in this case is 12mm). The second half is the thread pitch, which is the measurement of threads/inch (which in this case is 1.75).
What is M12 thread size?
| Tap size | Basic major dia (mm) | mm per thread |
|---|---|---|
| M10 x 1.5 | 10mm | 1.5 |
| M10 x 1.25 | 10mm | 1.25 |
| M12 x 1.75 | 12mm | 1.75 |
| M12 x 1.25 | 12mm | 1.25 |
Is A325 high strength?
Prior to its withdrawal in 2016, the ASTM A325 specification covered high strength heavy hex structural bolts from 1/2″ diameter through 1-1/2″ diameter. These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts.
Is A325 high strength bolt?
A325 bolts have a minimum tensile strength of 120,000 PSI for one inch or less diameters and 105,000 PSI for over one inch. This makes them weaker than A490, certain jobs do not require a structural bolt as strong as Grade A490.
Which is stronger A325 or Grade 8?
Strength Differences A325 bolts are typically manufactured from a medium carbon steel (although they can be made from an alloy) while SAE grade 8 bolts are made from a medium carbon alloy steel. Grade 8 bolts are significantly stronger than an A325.
How do you determine the length of a structural bolt?
What is the correct bolt length? The correct bolt length that should be used in an assembly is roughly 2 times the diameter of the bolt, plus the thickness of the material.
What thickness is M12?
M12 bolts are a metric sized bolt with a 12mm thread diameter.
