This means that the external thread must end flat at Dmaj, but can be rounded out below the minor diameter Dmin. Diameter and Lengths of the stud and bolt are covered in flange standard ASME B16.5 & B16.47. The outermost 1⁄8 and the innermost 1⁄4 of the height H of the V-shape are cut off from the profile. All other trademarks cited here are the property of their respective owners. Max. an M6 screw has a nominal outer diameter of 6 millimetres). The design principles of ISO general-purpose metric screw threads ("M" series threads) are defined in international standard ISO 68-1. Conversely, in an internal (female) thread (e.g., in a nut), the major and minor diameters are minimum dimensions; therefore the thread profile must end flat at Dmin but may be rounded out beyond Dmaj. Stainless Steel & Nylon Parts: M2.5 thread is tapped thru 9.6 MM in length M3 thread is tapped thru 12.7 MM in length. Our M6 fine thread studs include an allen socket drive for easy installation. The 1st choice column follows (approximately) the R10 series from ISO 3, while the 2nd choice column are rounded off values from the R20 series from ISO 3. M3.5 and larger threads are tapped thru 25.4 MM in lengths. Diameter and Lengths of the stud and bolt are covered in flange standard ASME B16.5 & B16.47. ISO 68-1: ISO general purpose screw threads — Basic profile — Metric screw threads. [4][5], ISO 262 specifies a shorter list of thread dimensions – a subset of ISO 261.[6]. We can leverage our USA and off-shore molding capabilities to deliver the right cord, when you need it. 1/4 0.250" (6,350 mm) M6 6,0 mm (0.24") 0.265" (6,7 mm) 5/16 0.3125" (7,938 mm) M8 8,0 mm (0.32") 0.328" (8,3 mm) 3/8 0.375" (9,525 mm) M10 10,0 mm (0.40") 0.397" (10,1 mm) Tolerance classes defined in ISO 965-1 can be appended to these designations, if required (e.g., M500– 6g in external threads). M3 and larger thread is tapped thru 25.4 MM in length. Lengths between 500 mm and 1 000 mm shall be graded in 20 mm steps. [2] Each thread is characterized by its major diameter, D (Dmaj in the diagram), and its pitch, P. ISO metric threads consist of a symmetric V-shaped thread.

In the plane of the thread axis, the flanks of the V have an angle of 60° to each other. 1996 - 2020 All Rights Reserved. Metric Bolt Head/Wrench Size. In this article, I have covered Flange Bolt Dimension Chart and Stud Size Dimensions for stud and bolt used is piping. The chart below shows metric bolt conversions and DIN numbers for fasteners. Metric Stud Bolt To Nut Size Chart. Image shown below indicates the nomenclature that used in the dimension chart. StayOnline provides the most reliable power cord supply chain management. The terms “coarse” and “fine” have (in this context) no relation to the manufacturing quality of the thread. Superfine pitch metric threads are occasionally used in automotive components, such as suspension struts, and are commonly used in the aviation manufacturing industry. Print this page . Metric bolt conversion data for industrial bolts/rods, machine screws and small diameter fasteners includes metric to standard bolt conversions. [7] Fine and superfine threads also have a greater minor diameter than coarse threads, which means the bolt or stud has a greater cross-sectional area (and therefore greater load-carrying capability) for the same nominal diameter. Note : * Non-preferred threads according to standard. [CDATA[
Flange Bolt Chart and Stud Size in mm In this article, I have covered Flange Bolt Dimension Chart and Stud Size Dimensions for stud and bolt used is piping. All dimensions are given in millimeters. Supplements: Metric hex nut dimensions calculator The relationship between the height H and the pitch P is found using the following equation where θ is half the included angle of the thread, in this case 30° :[3]. $('head').append('')
A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter) and the pitch P, both expressed in millimetres and separated by the hyphen sign, - (e.g., M8-1.25). Definitions of terms are located below the chart. This is because extra fine threads are more resistant to coming loose from vibrations. In addition, one or two smaller “fine” pitches are defined, for use in applications where the height of the normal “coarse” pitch would be unsuitable (e.g., threads in thin-walled pipes).
