## What is gauge in screw sizes?

The gauge of a screw is defined by the thickness (diameter) of the un-threaded part of the screw known as the shank. Ordinarily, in the United Kingdom the head size is roughly twice the diameter of the shank, although there are some exceptions associated with hybrid, hardened, DIN Standard (metric) and imported screws.

## What size is 4 gauge screw?

As a handy coincidence, the Gauge (imperial) roughly equals the screw head size in millimetres. A 4 gauge screw will have a head that is approximately 4mm wide.

## What is M6 screw?

M6 refers to a metric 6mm screw. The outside diameter of the threads is 6mm. The standard metric rack screw is actually an M6 x 1mm. The number “1mm” refers to 1 threads per millimeter. … You can identify an M6 screw by measuring the diameter with a ruler at slightly more than 7/32″ (0.228″).

## What does 6g screw mean?

As an example, a common screw thread tolerance is 5g6g, which indicates a 5g tolerance on its pitch diameter, and a 6g tolerance on its external (thread) diameter. … For instance, for a screw with both a 6g major diameter tolerance and a 6g pitch diameter tolerance, this would simply be written as “6g”.

## Is M6 the same as #6?

M6 threads are 6mm metric screws. The standard metric rack screw is called M6 x 1. The ‘M’ means it’s metric. The ‘6’ is the outside diameter measured in millimeters, and the ‘1’ is the distance between adjacent threads, also in millimeters.

## What diameter is a 6 32 screw?

#6-32 UNC screw

The #6-32 UNC is a UTS screw specifying a major thread diameter of #6 which is defined as 0.1380 inches (3.51 mm); and 32 tpi (threads per inch) which equates to a thread pitch of 0.031250 inches (0.7938 mm).

## How do I know what size screw I need?

The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4. The other factor is the screw’s diameter, or gauge. Screws come in gauges 2 through 16. Most of the time you’ll want to go with a #8 screw.

## How wide is #8 screw?

The #8 gauge screw has a major diameter of 0.17″ and 8 TPI. The screw is 1-1/4″ long, a measurement taken from the bottom of the head to the point.

## What does a #8 screw mean?

Their size is described as diameter, number of threads per inch (if used with a nut or in a threaded hole), and length in inches. … In all cases, the larger the number, the larger the size. Consequently a #8 screw is larger than a #4 screw, just as a 3 inch bolt is larger than a 2 inch bolt.

## What size is M5 screw?

Metric clearance and tapping drill hole sizes.

M5 5.5 4.2 mm
M6 6.5 5.0 mm
M8 9 6.75 mm
M10 11 8.5 mm
