Wrench Sizes Chart: Discover the right size with 3 charts

You found the place with multiple charts for quick reference! Here are the internal links for charts found in this post for multiple applications: Wrench Size Chart, Wrenches by Socket Size, or Converting SAE to Metric. A wrench sizes chart is a helpful reference tool that lists the different sizes of wrenches in order from smallest to largest. This chart can help you quickly determine which wrench size you need for a particular job. Whether you’re a professional mechanic or a DIY enthusiast, having a wrench sizes chart on hand can save you time and frustration.

Wrench sets will have a number of different sizes within them, so you won’t necessarily have to purchase more wrenches that aren’t in your toolbox.

How Wrenches Are Sized

There are two different methods of sizing wrenches – the standard method (SAE) and the metric sizing. In wrench sets, they will be all positioned in order from smallest size to largest.

SAE and metric nuts and bolts will need to be used with the corresponding wrench sizes. For example, an SAE nut will need to be used with an SAE wrench to ensure that you get the correct fit.

Similarly, a metric bolt should be used with a metric-sized wrench.

Alternatively, you can use a wrench sizes chart to convert SAE sizes to metric sizes, and vice versa.

This means that you’ll be able to use SAE and metric wrenches interchangeably with most kinds of nuts and bolts.

Wrench Sizes In Order

Standard wrench sizes in America are as follows, in inches: 1/4, 9/32, 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, and 1. These are set out from the smallest wrench to the largest, and you will be able to buy these wrenches individually or in wretch sets.

A metric wrench set usually includes the following metric wrench sizes: 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, and 24mm.

Wrench Size Chart

Below is the wrench size chart for both SAE and metric sizes. You can use this to convert wrench sizes from one way of measuring it to another.

The bolt diameter is another term for the amount of space between the two prongs of a wrench. This diameter will be the same as the nut or bolt that it can be used with. Use this wrench sizes chart to work out which nut and bolt the wrench can be used with.

Wrenches According To Socket Sizes

Now that you have the conversion chart for your wrench sizes, let’s take a deeper look.

Below is a table of SAE socket sizes. These refer to SAE tools, sockets, and bolts.

Converting SAE Sizes To Metric Sizes

If you need to convert metric sizes from standard sizing, you can use the wrench sizes chart below to help with that.

Bear in mind that metric sizes don’t always relate completely to standard wrench sizes, but there are different socket sizes from both methods of sizing that correlate quite closely to one another.

When converting SAE sizes to metric sizes, you will need to convert them between inches and millimeters. This chart can help you to convert sizes in regard to wrenches, sockets, and other tools as well.

Summary

I hope that the wrench sizes chart and conversion charts are useful to you! Remember to bookmark this page and come back to it any time that you need to work out a conversion for your wrenches, sockets, or other tools.

Different methods of sizing can be frustrating and annoying to people who are just trying to get a job done, but we hope that our charts today can be helpful with that moving forward.
