It is a special kind of projection of the Globe. AF: across flats: Commonly used when measuring the flat surfaces of a hex drive, such as a hex nut. Part of the bolt inside which the shear plane or planes pass through. Therefore the mean diameter dm is approximately: Strength properties for bolt steel according to EN 1991-1-8 Table 3.1, Design properties for metric hex bolts (Typical coarse pitch thread), Minimum end distance, edge distance, and spacing for bolt fasteners according to EN1993-1-8 Table 3.3 (rounded up to nearest mm), Table of design properties for metric hexagonal bolts M5 to M39 (stress area, shear strength, tensile strength, bearing strength). Flatness is can be measured using a height gauge run across the surface of the part if only the reference feature is held parallel. Distance definition: The distance between two points or places is the amount of space between them. 8 mm for M8 bolt.
