There are a few ways to determine bolt spanner size. One way is to measure the distance between the bolts. Another way is to measure the length of the spanner. The size of the bolt spanner is usually stamped on the head of the spanner.
To find the size of a bolt spanner, you will need to measure the distance between the innermost points of the jaws of the spanner. This measurement will tell you the size of the spanner.
How do I know what size spanner my bolt is?
Spanners come in different sizes, indicated by the width across flats. This is usually imprinted in millimeter (mm) values. Older British and current US spanners (wrenches) have inch sizes that are imprinted in intermediate sizes in fractions.
A spanner is a tool used to tighten or loosen bolts and nuts. Spanners come in a variety of sizes, which are typically based on the distance across the flats of the hexagonal nut or bolt they would fit. For example, a 17mm spanner would fit a nut 17mm across its flats. This is typically a nut to fit a 10mm diameter bolt (M10).
What size is a 3 8 spanner
There are a few things to keep in mind when converting between US inches and metric mm wrench and spanner sizes. First, it is important to remember that the metric system is based on the metric prefixes, which means that there are 10 mm in a cm, and 1000 mm in a meter. This means that there are 25.4 mm in an inch. So, to convert from inches to mm, you simply need to multiply by 25.4. For example, a 3/8 inch wrench would be 9.53 mm in size, and a 17/16 inch wrench would be 111.86 mm in size.
A metric spanner is a tool used to apply torque to a fastener, and is sized according to the fastener’s metric size. The most common metric spanner sizes are listed in the table below.

This table lists the bolt diameter and head/wrench size for the U.S. bolts. As you can see, the larger the bolt diameter, the larger the head/wrench size. This is so that the bolt can be tightened or loosened with the appropriate tool.
What size nut do I need for a 3/8 bolt?
The following is a US nut size table. The table lists the diameter and height of hex nuts.

Is M8 bolt same as 8mm
The M8 bolt has a shaft diameter of slightly under 8mm, which means that it should fit through an 8mm hole. However, the defined diameter of metric bolts is actually slightly larger than the actual diameter of the bolt shaft, so it’s important to check that the bolt will actually fit through the hole before using it.
As the pitch of M8 threads is 125mm and the TPI (Threads Per Inch) of 5/16 UNC threads is 18, which can be converted to 141mm per pitch, there is no chance to fit a M8 bolt to a 5/16 nut.

The thread diameter of an M8 Bolt is 8mm. However, we stock a range of various lengths so you can pick the right option for your next DIY project.
A wrench is a tool used to provide grip and torque around an object, such as to turn a bolt. The most common shapes are called open-end wrench and box-end wrench. In American English, spanner refers to a specialized wrench with a series of pins or tabs around the circumference.
There is no definitive answer to this question, as the appropriate bolt spanner size will vary depending on the specific application. However, a few general tips that may be helpful include:
– Consulting a torque chart: Torque charts are widely available and can be extremely helpful when selecting the appropriate wrench size for a given bolt.
– Checking the wrench size markings: Most wrenches will be marked with their size, which can be helpful in ensuring the correct size is selected.
– Considering the bolt head size: In many cases, the wrench size will be determined by the size of the bolt head. Therefore, it can be helpful to measure the bolt head before selecting a wrench.
There are a few ways to find out the bolt spanner size that you need. One way is to measure the bolt directly with a ruler or caliper. Another way is to look up the size in a spanner size chart. Once you know the size, you can select the appropriate spanner from a set.
