How are socket cap screws measured?
Measuring Bolts and Screws Length is measured from the point at which the head sits flat with the surface, to the tip of the threads. Hex, pan, truss, button, socket cap, and round head screws are measured from right under the head to the end of the threads.

How are metric bolts sized?
Metric nuts and bolts are commonly referenced using ‘M’ sizes, for example: M3, M8, M12. But the size of a metric fastener is more accurately specified using diameter, pitch and length dimensions, in millimeters. For nuts the size dimensions used are simply diameter and pitch.
What is M6 in standard?
M6 refers to a metric 6 mm screw. The outside diameter of the threads is 6 mm. The standard metric rack screw is actually an M6 x 0.1 mm. The number 0.1 mm refers to 0.1 threads per millimeter. You can identify an M6 screw by measuring the diameter at slightly more than 7/32″ (0.228″).
Are M6 and 1/4 the same?

What grade is a standard socket head cap screw?
Typical bolts are supplied as grade 5.8, 8.8, or 10.9. Socket cap screws are often available in grade 12.9, meaning it has a UTS of 1200 MPa and will yield at 90% of this (1080 MPa).
What are M3 and M4 screws?
As a rule of thumb, the diameter of the clearance hole is more than the diameter of the screw. The M3 screw’s clearance hole is either 3.5 or 3.2mm. The M4 screw has a clearance hole of at least 4.2mm.
How do you tell the difference between metric and standard?
Standard tools use the imperial or SAE measuring system, commonly used in the USA. Metric tools rely on the metric measurement system. The difference is in the units, where standard tools will use inches, feet, miles, and yards. The metric system uses millimeters, centimeters, meters, and kilometers for expression.
Is M6 the same as 6mm?
M6 refers to a metric 6 mm screw. The outside diameter of the threads is 6 mm. The standard metric rack screw is actually an M6 x 0.1 mm. The number 0.1 mm refers to 0.1 threads per millimeter.
Is M6 and 1/4 the same?
The size of a metric screw or bolt is specified as diameter, pitch and length, in millimeters (millimeters is abbreviated “mm”). For nuts, size will appear as diameter and pitch….Table 3.
