How big is a m8 nut?

The normal size of the M8 hex nut is 13 mm across opposite sides, the height can vary slightly depending on the thickness of the thread type of the nut about 80 percent of the nominal bolt diameter.

Correspondingly, how thick is an m8 nut?

Standard Metric Hex Nuts per ANSI/ASME B18. 2.4. 1M and B18. 2.4. 2M

Nominal Nut Dia. x Thread Pitch	Width Across Flats, S	Thickness M
Nominal Nut Dia. x Thread Pitch	Max	Min
M5 × 0.8	8.00	4.40
M6 × 1	10.00	4.90
M8 × 1.25	13.00	6.44

Likewise, what size is an m8 bolt in inches?

Tap size	Basic major dia (mm)	Basic major dia (inch)
M6 x 1	6mm	.2362
M8 x 1.25	8mm	.3150
M8 x 1	8mm	.3150
M10 x 1.5	10mm	.3937

Keeping this in view, how do I calculate nut size?

Stretch the tape measure across the nut's diameter to the flat-side directly across from the one your pulling from. If the nut is metric, count the number of lines on the tape measure to find the measurement. If you count 9 lines, the size is a 9-mm (millimeter) nut.

What are M sizes?

The "M" means "metric." Metric threads are designated by diameter and thread spacing. For instance, the most common bolt size used on bicycles is 5 x . 8, also known as "M5." This size is used for water bottle mounts, cable anchor bolts, fender/rack eyelets, shifter mounts etc. The "5" means the bolt diameter is 5 mm.

What size nut fits a 15mm socket?

The standard wrenches needed are: 11,13,15,17,19,22,24,27,30,32,36mm. I believe that the bold that goes with the 15mm wrench is normally an M8. M8s usually use 12 or 13mm heads.

What is thread pitch?

The thread pitch is the distance between threads expressed in millimeters (measured along the length of the fastener). For example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm.

How is thread count measured?

Thread count

It is measured by counting the number of threads contained in one square inch of fabric or one square centimeter, including both the length (warp) and width (weft) threads. The thread count is the number of threads counted along two sides (up and across) of the square inch, added together.

How do you determine thread size?

How to Determine Screw Size & Thread Count

Lay the screw down on a flat surface.
Place a steel rule down the axis of the screw.
Count the number of thread gaps within 1 inch of the screw.
Divide the count of thread gaps into the length.
Place the screw on a flat surface.
Lay a steel rule between two screw threads and measure across the diameter.
