A pin jet nozzle for providing an evaporative fog in evaporative cooling systems or the like has a body member with an internal bore for receiving fluid under pressure, and an orifice receiving chamber integrally formed in the upper surface of the body member. The orifice receiving chamber is unitary with the body member and in fluid communication with the internal bore. An orifice member is directly secured in the orifice receiving chamber so that an orifice of the orifice member is coaxial with the internal bore. A pin member has an impingement pin with an impingement face that is spaced from, and in alignment with, the orifice.
