What does m3 mean on screws?
You asked about M3, M4, etc - that describes (only) the outside diameter of the screw - or the size of an unthreaded hole the screw would slip through. A full description is like M 6 - 1 X 25 Which describes the outer diameter (6) , the distance from one thread to the next (1) (pitch) and the length (25) (all in millimeters.)
What does M3 0.5 mean?
Full Member. 0.5 is the pitch, which is standard pitch for m3.
What does M3 5 screw mean?
2.5 holem3 .5 pitch =2.5 hole. m4 .7 pitch =3.3 hole. m5 .8 pitch =4.2 hole. m6 1.0 pitch=5.0 hole. all taps have size and pitch on them hope this has helped.Nov 17, 2003
What does M3 stand for in screws?
M3 is usually 3mm x . 5, the second number (. 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.May 28, 2020

What is M in bolt size?
The letter 'M' indicates that this bolt uses a metric thread. The number '8' refers to the nominal diameter of the bolt shaft in millimeters. The number 1.0 is the thread pitch of the bolt, which is the distance between threads, in millimeters. And the final figure, 20, is the length in millimeters.Jun 19, 2020

How do you read thread size?
Thread sizes are given in nominal sizes, not in the actual measurement. The exact measurement is slightly below the named or nominal size. For example, a 6mm bolt may measure 5.8mm or 5.9mm, but it is called 6mm bolt. It is also common to use “M” before the bolt size, such as M6 for a 6mm bolt.Aug 24, 2015
Basic profile
The design principles of ISO general-purpose metric screw threads ("M" series threads) are defined in international standard ISO 68-1. Each thread is characterized by its major diameter, D ( Dmaj in the diagram), and its pitch, P. ISO metric threads consist of a symmetric V-shaped thread.

Preferred sizes
ISO 261 specifies a detailed list of preferred combinations of outer diameter D and pitch P for ISO metric screw threads. ISO 262 specifies a shorter list of thread dimensions – a subset of ISO 261.
Spanner (wrench) sizes
Below are some common spanner (wrench) sizes for metric screw threads. Hex head widths (width across flats, spanner size) are for DIN 934 hex nuts and hex head bolts. Other (usually smaller) sizes may occur for reasons of weight and cost reduction.
What are my radon levels, and what do they mean?
Measuring radon levels in a home or building is key to protecting the health of anyone breathing the air, but interpreting those levels is not quite as exact without a radon detector. As they say, everything is relative, and what is an acceptable radon level to one country or organization may differ from what is acceptable to another.
Radon level measurement units
Radon is generated by the radioactive decay of radium, an element which was originally discovered in 1898 by Pierre Curie, Marie Skłodowska Curie and G. Bemont 2. Radioactive elements are unstable, always in a constant struggle, deciding whether to hold onto all of their atomic energy in the nucleus or release some of it.
Safe radon levels
The best radon level measurement would be zero. Unfortunately, that's not possible. The average global outdoor radon level varies between 5-15 Bq/m3, equal to 0.135-0.405 pCi/L. For every 99.9 Bq/m3, or every 2.7 pCI/L increase in long term radon exposure, lung cancer risk rises 16% 4.

Airthings is on a mission to ensure people around the world take control of their air quality through simple, sustainable and accessible technology solutions; making radon and air quality solutions an essential and universal element for every building or home. That is why radonmap.com was created.
Healthy radon levels
A concrete answer to ‘what are healthy radon levels’ is highly disputable. Zero would be the natural answer, except that radon is a naturally occurring, radioactive gas that is in the air all around us. It is unavoidable, and in high levels over long periods of time can be dangerous.
Radon level chart
Airthings View Plus, Wave Radon and Wave Plus have a color-coded visual indicator. This makes it easy to get an overview of the air in your home. In addition, you can check in the Airthings app if the radon sensor is good (green), fair (amber) or poor (red).
A simple solution
High radon levels can be fixed easily and simply. Whether it is following easy radon reduction tips, increasing ventilation, performing DIY fixes or contacting a radon mitigator, radon gas levels can be improved dramatically. The first step is to monitor, so that you can be alerted to high levels and make small changes where necessary.
