M-POINT

Agradezco la ayuda. Siguiendo instrucciones iniciales del cliente, aquellas abreviaturas o siglas que no se pueden "descifrar", quedan igual. En este caso me incliné por dejar "punta m" (es punta, ya que se refería a las puntas de los pernos). Si bien "punta media" quizá sea válida, en todo caso, "punta m" quedaría bien también.
Saludos y gracias nuevamente!

Seems we are dealing with chassis parts, at http://auto.ihs.com/document/abstract/WRXFGBAAAAAAAAAA

it says Typical Application. This coating is intended primarily for bulk processed small steel parts such as bolts, screws and nuts used on exterior and interior visible parts (cosmetic applications). This coating is especially suitable for internal drive (cross recess, 6 lobed socket etc.) threaded fasteners and self drilling and tapping screws.

Would M Pt be the Melting Point referring to the coating?
