## What are the standard metric threads?

ISO Metric Machine Screw Thread Dimensions

Thread Size Nominal Diameter (mm) Thread Pitch (mm)
M8 8.0 1.25
M10 10.0 1.50
M12 12.0 1.75
M14 14.0 2.00

## What are the different types of metric threads?

If you have the metric threads, the pitch gauge identifies the distance between each individual crest in millimeters….STEP 2. Determine the Pitch.

Thread Type Pitch Size
BSPP (British Pipe) 11, 14, 19, 28
BSPT (British Pipe) 11, 14, 19, 28
Metric Parallel 1.0, 1.5, 2.0
Metric Tapered 1.0, 1.5, 2.0

Is standard for metric screw threads?

10 – Metric screw threads….Metric screw threads.

Standard and/or project (19) Stage TC
ISO 262:1973 ISO general purpose metric screw threads — Selected sizes for screws, bolts and nuts 95.99 ISO/TC 1
ISO 262:1998 ISO general purpose metric screw threads — Selected sizes for screws, bolts and nuts 90.93 ISO/TC 1

### How do you specify metric threads?

Designation. A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter) and the pitch P, both expressed in millimetres and separated by the multiplication sign, × (e.g., M8×1.25).

### What is standard M10 thread?

Metric thread sizes are specified differently than inch thread sizes. Inch sizes are specified using the nominal major diameter and the number of threads per inch….ANSI Equivalents for ISO Thread Sizes.

ISO THREAD DESIGNATION ANSI EQUIVALENT
M5 M5x0.8
M6 M6x1
M8 M8x1 M8x1.25 M8x1
M10 M10x1.25 M10x1.5 M10x1.25

What is the difference between standard and metric threads?

Metric fasteners are measured by length and pitch, or the distance between threads. So the systems are opposite in a way: The higher the TPI in a standard bolt, the finer the threads because there’s more squeezed into a set space. The greater the pitch on metric fasteners, the more distance between threads.
