While there is no precise correlation between SAE fractional and metric measurements, there are many sockets that are close enough in size to be used interchangeably, in some circumstances. For example, 5/16 and 8 mm, 7/16 and 11 mm, 5/8 and 16 mm, 3/4 and 19 mm, 7/8 and 22 mm, and 15/16 and 24 mm.

What is a 28mm socket in standard?

Metric socket wrenches fit fasteners where that nominal length is a round number of millimeters (8mm, 10mm, 15mm). “Standard” (often “inch” or “SAE”) socket wrenches fit fasteners where that nominal length is a round fraction of an inch (1/4″, 1/2″, 13/16″).
Can SAE and metric interchangeable?
Are SAE & Metric Interchangeable? ... Yes, you can use some sockets on both metric and SAE sizes. However, you need to be careful, as most times they are not exactly the same, and you can strip a bolt by using an SAE socket on a metric bolt and vice versa.
How do you tell the difference between metric and SAE?
Metric and SAE fasteners are measured differently and with different vocabulary. SAE nuts, bolts and screws are measured by their thread count, or TPI (threads per inch) and their length. Metric fasteners are measured by length and pitch, or the distance between threads.May 22, 2019
