A track fitting assembly for removably securing a seat through a swivel bearing to a generally channel-shaped track secured to the fuselage of an aircraft. The track fitting assembly includes a forged body member having spaced track lugs projecting laterally from a narrow finger portion. The body member has a socket which receives a threaded shear plunger adjusting screw such that a head on the adjusting screw moves into the socket to indicate when the shear plunger is properly seated to lock the track lugs in the track.

[ Having described the invention, I claim:] [1.] A shear plunger assembly for use in combination with a track fitting body for removably securing a seat leg to a generally channel-shaped track having an elongated groove formed between a pair of flanges, each of the flanges having spaced openings positioned to form a series of spaced receptacles having flange lip segments between the receptacles, wherein at least a portion of the track fitting body is a first color and has a threaded socket and a finger portion which has a width less than the width of the groove formed in the track and a plurality of spaced track lugs projecting laterally from the finger portion, said shear plunger assembly comprising:a shear head on the shear plunger assembly;mounting means for mounting said shear head on the track fitting body, said mounting means positioning said shear head a distance relative to the track fitting lugs which is not equal to the distance between adjacent spaced receptacles in the track; anda screw having a threaded central portion, a stem portion and a painted head portion, said painted head portion being painted a second color and having a smaller outside diameter than said threaded portion and a smaller outside diameter than said threaded socket, said screw being connectable between said shear head and the track fitting body for moving said shear head relative to the track fitting body, said painted head portion of said screw being concealed in the threaded socket when said shear head is positioned in a receptacle in the track flange to prevent movement of the track fitting lugs longitudinally of the track, said painted head portion being clearly visible when said shear head is not properly positioned in a receptacle in the track flange.
