A piston ( 5 ) for a two-stroke engine ( 1 ) has a piston base ( 19 ) and at least one piston pin boss ( 24 ). The piston pin boss ( 24 ) has a bore for accommodating a piston pin. At the piston pin boss ( 24 ), two mutually opposite-lying planar clamping surfaces ( 36, 37 ) are formed. The piston ( 5 ) is produced in a pressure die cast process and is thereafter clamped at the clamping surfaces ( 36, 37 ) and a stop surface ( 35 ). In this clamping state, all machining operations of the piston ( 5 ) can be carried out so that a high dimensional stability of the piston ( 5 ) results.
