What does m8 1.25 bolt 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.

Are m10 and 3/8 the same?

Since 10 mm is bigger than 3/8″, the simple answer is, “NO”. But you CAN drill the hole out to either 25/64″ (for 3/8-24) or letter “X” (. 397″)( for 3/8-16), and tap for a Helicoil.

How do you measure the width of a bolt?

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 m8 bolts 8mm?

All dimensions of the bolt (and nut) are a parameter of its basic diameter. The “M8” refers to an approximation of the major diameter of the thread of 8mm – actually slightly less, like 7.9, as the sharp edges are rounded off.

What are standard bolt sizes?

Typically, machine bolt sizes range from 1/4″ to 1 1/4″ for square heads and 3/8″ to 1 3/4″ in diameter for hex heads, and lengths span from about 3/4″ to 18″ for square and 6 1/2″ to 24″ for hex heads. Measure length from under the head to the threaded end of the bolt.

How do you measure bolt head size?

Multiply the first number which is the bolt size in inches or millimeters, by 1.5 using a pocket calculator, if necessary. For example, for the numbers in Step 1, 1/2 x 1.5 = . 75 or 3/4, which is the wrench size needed for this standard-sized bolt.

What do the numbers mean on bolts?

In addition, most metric bolts are identified by a number stamped on the bolt head, such as 4.6, 5.8 or 10.9. The number has nothing to do with the size, but does indicate the relative strength of the bolt. The higher the number, the stronger the bolt. … A metric fastener could be designated M12 x 2, for example.
