    Default Tektronix 402x terminal keyboard enclosure -- 0.188" hex set screw?

    See http://bitsavers.trailing-edge.com/p..._2_Jan1980.pdf page 291 and following.

    I have a Tektronix 4024 terminal and the keyboard enclosure is similar to the 4027 keyboard. There are 4 tiny hexagonal set screws along the back of the keyboard enclosure that allow you to open up the enclosure. The 4027 parts listing gives this description for the set screws:

    SETSCREW:4-40 X 0.188 INCH,HEX SOC STL

    Manufacturer info:

    HOLO-KROME CO., 31 BROOK ST. WEST, HARTFORD, CT 06110

    Does anyone know what the right size hex wrench is for removing these without stripping the innards?

    Thanks.

    OK, the small hex driver in the "iFix It" kit took care of it.
