When specifying a threaded rod, the length comes after the class of fit. The two are commonly separated by an “x” (read as “by”). Length should be in units of inches for Inch-Standard fasteners and millimeters for Metric fasteners.

## How is a threaded rod measured?

Threaded rod is measured Diameter-Threading x Length. For example, you may find a threaded rod measuring 1/4″-20 x 6ft. The 1/4″ is the rod’s diameter, the 20 means there are 20 threads per inch of rod, and the 6ft is how long the rod is. Most threaded rod is available in either three-foot or six-foot lengths.

## What size is a #10 threaded rod?

#10-24 x 36 in. Zinc-Plated Threaded Rod.

M8 8 1.25
M10 10 1.5
M12 12 1.75
M16 16 2

## What size is a #8 threaded rod?

Thread pitch is the distance from the crest of one thread to another crest measured along the length of the thread. Pitch is best measured using a thread pitch gauge. So-called “English,” “Standard,” “Imperial,” or SAE threads are designated by the frequency of how many threads are counted along one inch.

## How is TPI measured?

As the name suggests, TPI is measured by counting the number of thread peaks along a 1 inch length. The TPI measurement is then often affixed to the diameter of the thread to form a common imperial thread size, e.g. ‘1/4-20’, which would denote a ¼ inch diameter, and 20 threads per inch.

## What size is #10 24 threaded rod?

For a 10-24 screw this is 0.19 of an inch as the major diameter and 0.1379 as the minor diameter.

## What sizes do all thread come in?

As standard, allthread comes in steel across a number of grades including 4.8, 5.8, 8.8, 10.9 and 12.9 – as well as other variations including stainless steels and Duplex stainless steels, which are characterised by their high yield strength and improved corrosion resistance.
