Metric Bolt Measuring Guide How To Measure A Fastener Pro Bolt Metric fasteners are specified with a thread pitch instead of a thread count. the thread pitch is the distance between threads expressed in millimetres (measured along the length of the fastener). for example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm. Step 3 measure length of bolt. since the length of the bolt is the last number in a metric measurement, you should measure for it last. start from right below the head, including only the shank, and measure to the tip. this rule for bolt length holds true for most types, including cheese, hex, pan, socket, button, and low socket head types.
Metric Bolt Measuring Guide How To Measure A Fastener Pro Bolt Common metric bolt grades include: grade 4.6: typically used for light duty applications. it has a tensile strength of 400 mpa and a yield strength of 240 mpa. grade 8.8: one of the most common grades, suitable for medium duty applications. it has a tensile strength of 800 mpa and a yield strength of 640 mpa. Bolts come in two major standards: metric and imperial (sae). metric bolts are measured in millimeters, while imperial bolts are measured in inches. for instance, a bolt labeled m10 has a 10mm diameter, whereas a 3 8″ bolt has a diameter of 0.375 inches. M12 x 25 = 12 mm diameter, coarse thread is assumed (1.75 mm), 25 mm long. m12 is a matching coarse threaded nut. (to avoid confusion, we always include the thread pitch for both coarse and fine metric fasteners.) if you normally work with inch fasteners, pitch can be a little confusing—pitch is the distance between adjacent threads. What do all of these screw and bolt sizes mean? in this video, we break down how screws & bolts are sized and how the us measurement system and metric measur.

Metric fasteners are specified with a thread pitch instead of a thread count. the thread pitch is the distance between threads expressed in millimetres (measured along the length of the fastener). for example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm. in general smaller fasteners have finer thread so. Measure screw diameter, or screw size, by measuring the width of the threaded part of the screw. this corresponds to the first number of the thread size. for inches, any diameter smaller than 1 4" is indicated by a number, referenced in the table below (e.g. 8 corresponds to 0.164"). for metric screws, this is the number of millimeters preceded.
