Is M8 the same as 8mm?

M8 is the designation for a metric (M) sized bolt or screw that is 8mm (8) in diameter. This is roughly equivalent to a 5/16 bolt or screw.

Which is bigger M8 or 5 16?

Metric	Closest Inch
M8-1.25	5/16-18 (Smaller)
M10-1.5	3/8-16 (Smaller)
M12-1.75	1/2-13 (Larger)
M14-2.0	9/16-12 (Larger)

Is M10 bigger than M8?

10mm is larger than 8mm. The second number is the thread pitch. The nut and the bolt need the same pitch.

Are M10 and 3/8 the same?

That said, they are very close, the 3/8" bolt is about 0.019" smaller and the pitch's are very close so the 3/8 -16 bolt will thread in the 10mm x 1.5 but the 10 x 1.5 bolt will not fit the 3/8 but..

Are M6 and 1/4 the same?

6mm equal to 0.2362 inches. Your 6mm spinner will "work" on a 1/4" shaft, but you may have to ream out the hole a little to get it to slide on easily.

What is M10 in mm?

Size	Spanner	Allen Key
M8	13 mm	6 mm
M10	17 mm	8 mm
M12	19 mm	10 mm
M16	24 mm	14 mm

What does 8.8 mean on a bolt?

So, in English, a Property Class 8.8 bolt is a bolt with a nominal tensile strength of 800 MPa and a nominal yield strength that is 80% of that nominal tensile strength, so 640 MPa.

What does M10 mean on a bolt?

M10-1.0 x 20 Taking a closer look at this description, let's explore its meaning: 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.

Can I use 5/16 instead of 8mm?

For the threaded rod 8mm vs 5/16" makes literally no difference. For the smooth rods 5/16" will work, but will not work with LM8UU linear bearings. You would have to have bearings or bushings made specifically for 5/16" rod.

Are 8mm and 5/16 the same?

8mm = 5/16 inch. 9mm = almost 3/8 inch. 10mm = just over 3/8 inch. 11mm = almost 7/16 inch.

What does M8 mean?

m8 (plural m8s or m8's) (Internet slang, text messaging) Abbreviation of mate.

What does M5 mean?

Bolts and nuts described as M5 means they are bolts or nuts with threaded 5 mm bodies. Additional numbers in the description indicate thread pitch and length. The M series metric fasteners have standardized pitches and diameters and head wrench sizes.

Is an M10 bolt 10mm wide?

What size nut (M12, M14) fits a bolt which is 10mm in diameter? If the bolt is 10mm in diameter (nominal), and metric, it will have a M10 thread.

Is a M10 bolt 10mm?

Steel bolt with M10 metric thread. Metric threads are designated with a capital M plus an indication to their nominal outer diameter and their pitch: This bolt is M10 x 1.5 - which means the outside diameter is 10mm and the threads are 1.5mm apart (the most common thread pitch for M10).

What is M10 equivalent to?

Metric coarse	Metric fine	BSF/BSW
M10 x 1.5	M10 x 1.25	3/8"
M12 x 1.75	M12 x 1.25	1/2"
M14 x 2	M14 x 1.5	9/16"
M16 x 2	M16 x 1.5	5/8"

What size hole is M10?

Size	Pitch	Drill
M10	0.75	9.25
M10	1	9
M10	1.25	8.75
M11	0.75	10.25

Is M12 the same as 12mm?

A: Yes. M12 is a 12mm diameter thread. You have to be sure the thread pitch measured in threads per millimeter (1.5 here) is the same as what u need.

What is bigger M6 or m12?

The main difference between 10-32 and 12-24 threads is their dimensions. 10-32 screws have a diameter of 3/16″ (4.8mm) where as 12-24 screws have a diameter of 7/32″ (5.6mm). M6 threads are 6mm in diameter, only . 4 mm larger than 12-24 screws.

Will a 1/4 inch bolt fit a 6mm hole?

The holes that are slightly large of 6mm are actually for 1/4" bolts. As they say, the bolts are 1-1/4" long. Typically this will be 1/4-20 unless there is an extraordinary need for strength. Since they are bolt-nut pairs, you may be able to substitute 6mm, but the 1-1/4" length will still be essential.
