Find out the different cross-sectional dimensions of any metric bolt's external thread and nut's internal thread using this thread calculator, given the thread pitch, basic major diameter, and tolerance class details of the threads.
- Pitch Diameter Calculator
Since this is a callout for a metric bolt thread, our first...
- Pitch Diameter Calculator
The Metric thread standard ISO 965-2 provides the limits only for classes 6H & 6g*. In all other cases, calculations must be made manually according to the below formulas or by our Threading Calculator. * For threads over 1.4 mm and classes 5H & 6h for threads up to and including 1.4 mm.
Calculate external and internal metric thread dimensions including major diameter, minor diameter, pitch diameter and thread tolerance according to ISO 724 and ISO 965 standards.
2 Φεβ 2021 · Here is the metric thread sizes table defines standard metric external thread size M1.6 to M18 per. ANSI/ASME B1.13M-1995. All units in mm. Here we’ll focus on the thread dimensions explained and the standard imperial/metric thread sizes chart.
Select your preferred unit of measurement and thread type. The calculator will automatically populate values for critical thread dimensions. These include dimensions such as basic diameter, minor diameter, pitch diameter, tap drill diameter, length of engagement, and more.
Count the threads: Tally the number of complete threads within the measured length. Apply the formula: Metric: Pitch = Measured length / Number of threads. Imperial: TPI = Number of threads / Measured length (in inches) Measure 10 complete threads on a bolt, spanning 15 mm. Pitch = 15 mm / 10 = 1.5 mm.
1 mm = 0.039 inches. Metric Bolts - Proof Loads. Download and print metric coarce threads clearance and tap drill chart. Metric Threads - Finer Threads. It is common to designate metric fine threads with the capital M plus an indication to their nominal outer diameter and their pitch: M size x pitch. Example: M 10 x 1.5.
