Once you've identified which metric wrench you would use, look at the chart to locate its SAE counterpart. Now, we do realize that the chart doesn't look complete on the metric side. However, the only common wrench size that isn't included in the chart is 18 mm, and it's counterpart is 45/64″. If you don't have that size, don't worry—neither do we.

Here is Lightning Bolt's Metric Bolt Thread Pitch Chart. In the Imperial "inch" system, threads are commonly referred to by measuring an inch, and counting how many threads are inside that measurement. The metric system's "pitch" is commonly viewed as the reverse of TPI in that it is the "DISTANCE" measured between two adjacent threads.

3-48 x .5 Let's break it down together: The first number is the screw gauge. Since it's #3, we can look at the chart and determine the major diameter and threads per inch. The second number is the TPI. 48 threads per inch indicate that the screws are coarse, not fine. Finally, the third number indicates the screw length.

The design principles of ISO general-purpose metric screw threads ("M" series threads) are defined in international standard ISO 68-1. Each thread is characterized by its major diameter and its pitch. ISO metric threads consist of symmetric V-shaped thread. In the plane of the thread axis, the flanks of the V have an angle of 60° to each other.

Metric Threads - Coarser Threads The table below indicates some of the most used coarse threads up to size M 68. Note that the ISO 724 standard specifies threads up to M 300. The table below is not complete. 1) For metric threads pitch is the distance between threads. 1 mm = 0.039 inches Metric Bolts - Proof Loads
