Socket Head Cap Screw Size Chart This chart contains information on number, metric and fractional number socket head cap screws, along with tap drill information. If all else fails, you may want to use our Drill Size Conversion Table or our Tap Drill Size Calculator .
socket wrenches metric sizes. The tables below show the commonly-available sizes of metric socket wrenches and the fasteners they fit. A 12-pt socket fits both hexagonal, square, and 12-pt heads (the last found mainly in aerospace bolts, but also on automobile engines as, for example, head bolts).

The length of a machine screw or bolt is indicated by a following x and the length expressed in millimetres (e.g., M8-1.25×30 or M8x30). Tolerance classes defined in ISO 965-1 can be appended to these designations, if required (e.g., M500- 6g in external threads).
Position of Head: The axis of the head shall be located at a true position relative to the axis of the screw shank within a tolerance zone having a diameter equivalent to 6% of the specified maximum head diameter, or the specified maximum width across flats of hex and hex flange heads, regardless of feature size. All tolerances are plus and minus.
Monster and dinosaur movies are notorious for getting the size of (real) creatures wrong. Using a thread length of 50mm (estimate), an M8 bolt, and steel with a shear strength of 270MPa, we can.
Calculation of dimension "F" is as follows: For Plug Taps M8 and smaller: F = Insert Nominal Length (Q) + .5 (Bolt Nominal Diameter) + 4P (Tap Chamfer) + 1P (allowance for countersink and maximum.

Fastener Designation First, when ordering or identifying the dimensions of a metric fastener, all metric fasteners are preceded by the capitalized letter ‘M’. Then, similar to how inch series fasteners are identified, the diameter is listed with the thread pitch, length and property class. For example: M12 x 1.5 x 50, 10.9 hex cap screw.
