Description / Abstract:
To establish recommended hole sizes for use with protruding head
metric threaded fasteners primarily used on propulsion equipment,
and provide the recommended positional tolerance for use with these
holes.
Application:
The data for hole sizes and the positional tolerances provided
in this document are suitable for protruding head fasteners based
on the dimensional data in MA1518 for sizes 3 thru 20 mm nominal
diameter, and with a strength class less than 1250 MPa
