Measuring Square Bolts for 8 Point Sockets: A Step-by-Step Guide (2023 Update)

Measuring a square bolt for an 8 point socket requires a few steps. Here's a simple guide to follow:

Measure the width of the bolt across the flats (the parts of the bolt that are parallel to each other). This measurement is referred to as the bolt's "across flats" dimension.
Determine the socket size that corresponds to the across flats dimension of the bolt. Sockets are typically labeled with their size, but if you don't have that information, you can use a socket size chart to match the across flats measurement to the corresponding socket size.
Make sure that the socket you're using is an 8 point socket. 8 point sockets are designed specifically for square bolts, and they have 8 points of contact with the bolt, as opposed to the 6 points of contact of a standard socket.
Once you have the correct socket size, you can use it to remove and tighten the square bolt.
If you don't have the socket size chart, you can measure the diagonal measurement of the square bolt, which will be slightly larger than the across flats measurement. You can use this measurement to find the correct socket size.

It's important to note that the measurement should be taken in inches or millimeters, depending on the socket size chart you use. Additionally, when measuring the bolt, make sure that the measurement is accurate and precise to ensure that you have the correct socket size. It's also important to note that some sockets are labeled with the measurement of the across corners, instead of the across flats. It is important to use the correct measurement in order to have the correct socket size. It's always a good idea to double check the measurement and the socket size chart before making a purchase.

Additionally, when using the 8 point socket, ensure that the socket is seated properly on the bolt and that the points of contact are properly aligned with the corners of the bolt. This will ensure that the socket is securely attached to the bolt, and that you can safely remove or tighten the bolt.

It's also a good practice to periodically check the sockets for wear or damage, as well as the bolts for any signs of damage, like rounding or deformation, to avoid any issues when trying to remove or tighten them.
