Which spanner for which bolt?

The size and type of spanner you need to use on a bolt depends on the bolt head size and shape, as well as the width of the bolt’s shaft. For example, a hexagonal bolt head will require a different spanner to a round bolt head. The most common type of spanner is the wrench, which come in various sizes to accommodate different bolt sizes.

There is no definitive answer to this question as it depends on the specific bolt in question and the desired level of tightness. However, as a general rule of thumb, a smaller spanner (such as an 8mm) is usually better for smaller bolts (such as those found on wheels), while a larger spanner (such as a 13mm) is usually better for larger bolts (such as those found on engine parts). If in doubt, it is always best to consult a mechanic or other expert to ensure that the correct spanner is used.

How do I choose a bolt spanner?

The most common way to calculate the size of a spanner (or wrench) for a given bolt is to take the bolt’s diameter (in millimeters or inches), multiplied by 1.5. This will give you the minimum size spanner that you will need for the bolt.

For example, for a 6mm bolt, you will need a 9mm spanner. For an 8mm bolt, you will need a 12mm spanner. For a 10mm bolt, you will need a 15mm spanner.

It is always a good idea to have a few different size spanners on hand, as it is not always possible to get an exact match. For example, if you only have a 10mm spanner and come across an 8mm bolt, you can still use the 10mm spanner, but it will be a bit more difficult.

A spanner is a tool used to provide extra torque to turn a nut or bolt. Modern spanner sizes refer to the distance across the flats of the hexagonal nut or bolt they would fit. A 17mm spanner therefore fits a nut 17mm across its flats and this is normally a nut to fit a 10mm diameter bolt (M10).

Which spanner is used for M8 bolt

A metric spanner is a tool used to measure the size of a bolt or other object in metric units. The most common metric spanner sizes are M6, M7, M8, and M10.

A metric spanner is a tool used to measure the size of an object. It is typically used in conjunction with a ruler or caliper. The size of a metric spanner is expressed in millimeters (mm). The most common sizes are: 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, and 16mm.

How do you match a bolt to a nut?

The diameter of a bolt is usually the outside diameter of the threads. To find the right size nut and washer, match the outer diameter of the bolt to the inner diameter of the nut and washer. For SAE nuts and bolts, diameters of 1/4 inch and smaller are listed with a # and a whole number (a bolt with a major diameter of 3/16 inch is a #10 bolt).

The size of a US bolt head and wrench can be determined by the bolt diameter. For example, a hex bolt with a 1″ diameter would require a 1-1/2″ wrench, while a square bolt with the same diameter would require a 1-5/8″ wrench.

What is 14mm spanner for?

The wrench is a tool that is used for fastening nuts and bolts. It is a very versatile tool that can be used for a variety of tasks. The wrench is a very important tool for anyone who works with machinery or repairs things around the house.

There are a few things to consider when choosing the right bolt for a joint. The first is to identify the load case and determine the necessary clamping force. The second is to choose the smallest bolt diameter that can support the clamp load. The third is to choose an effective bolt securing method. The fourth is to decide on the most appropriate tightening method.

What size spanner is between 11mm and 12mm

A wrench is a hand tool used to provide mechanical advantage or torque to turn objects. It is usually used to turn a bolt or a nut. Most wrenches are made of metal or strong plastic and are used to turn metal objects. There are different types and sizes of wrenches. The size of the wrench is usually indicated by the width of the jaw. Wrenches come in different sizes, from very small to very large. The size of the wrench you need depends on the size of the bolt or nut you need to turn.

If you need to know the threads per inch of a metric fastener, there are a couple different ways to do so. The first is to convert the pitch from millimeters to inches (by multiplying by 0.03937), and then divide 1 by that number. Alternatively, you can consult the table below.

What size spanner fits a M8 nut?

These nuts are shear nuts made of A4 stainless steel, and have a 13mm spanner size. They are used in a wide variety of applications where a high strength fastener is required. The A4 designation means that they are made of a material that is corrosion resistant and has a high strength-to-weight ratio.

When it comes to hole sizes for metric bolts, it’s important to note that the bolt shaft diameter should be slightly under the size of the hole. So, for example, an M8 bolt would have a shaft diameter that’s slightly under 8mm, meaning that the bolt should fit through an 8mm hole. This is important to keep in mind when making holes for metric bolts, as you want to make sure the holes are big enough for the bolts to fit through.

Is M6 bolt same as 6mm

M6 metric screws have a 6 mm outside diameter and 1 mm thread pitch. These screws are commonly used in rack-mount applications.

These are fully threaded M6-100 x 10MM hex head cap screws made of stainless steel 18-8. There are 100 pieces in total. The thread size is M6 and the bolt length is 10MM.

Are M6 bolts 6mm?

M6 Bolts have a thread diameter of 6 millimeters, making them great for smaller detail situations without compromising on load strength. These bolts typically have a smaller diameter head, and are used in a variety of applications where a lower profile is necessary. While they may not be suitable for every situation, M6 Bolts are a versatile option for many projects.

Metric bolts are typically marked with a number that indicates the material strength or class. The most common classes are 58, 88, 109, and 129. The higher the number, the stronger the material of the fastener.


There is no definitive answer to this question, as the appropriate spanner (wrench) to use for a given bolt depends on a number of factors, including the size and shape of the bolt head, the amount of torque required, and the type of material the bolt is made of. In general, however, a few basic rules can be followed:

– Use the smallest spanner that can fit around the bolt head without slipping. This will minimize the risk of damaging the bolt head.

– If the bolt is very tight, use a longer spanner to increase leverage.

– If the bolt is made of a soft material such as brass, use a softer spanner (e.g. made of plastic) to avoid damaging it.

There is no one answer to this question as it depends on the specific spanner and bolt in question. However, in general, it is best to match the size of the spanner to the size of the bolt, and to use the appropriate type of spanner for the type of bolt (e.g. a ratchet spanner for a nut).
