Metric Bolt Thread Pitch Chart.
So what is a thread’s “pitch” on a bolt? As fastener manufactures, we got you covered. Bellow are ISO/DIN accepted thread pitch charts for commonly found metric fasteners. 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.
As a fastener manufacturer, we understand that there are many important aspects of a thread to ensure proper fit and engagement. Many find that the metric system is actually easier since many of the measurements are in the same unit and there are no fractions to deal with. As a supplier of metric nuts, and metric bolts, Lightning Bolt has a wide variety of metric fasteners to offer… Including special metric bolts, and large diamter metric bolts. Below you will find a Metric bolt thread pitch chart.
