ABSTRACT:
A novel fastener is provided for securing a valve actuator housing to a valve mounting flange. The fastener, according to the present invention, comprises an elongated and generally cylindrical pin member which threadably engages the valve mounting flange so that a portion of the pin member extends outwardly from the valve mounting flange. The protruding portion of the pin member is received within an appropriate bore formed in the bottom of the valve actuator housing as the valve actuator housing is positioned on the valve mounting flange. A threaded transverse bore radially intersects the housing bore and threadably receives a locking screw. Upon tightening, the locking screw abuts against a reduced diameter circumferential portion of the pin member and, thus, locks the valve actuator housing to the valve mounting flange.
