The invention relates to a three-dimensional adjustable hardware system. According to the invention, at least one of the hardware bodies (18) comprises at least one guide pin (28) for the purpose of adjusting the hardware system (10) in the z-direction and the housing, in which the at least hardware body is arranged, comprises at least one threaded pin (30, 32), wherein the guide pin (28) and thereby the hardware body (18) are moved relative to the housing in the z-direction when the threaded pin (30) is rotated. For the purpose of adjusting the hardware system in the x-direction at least one of the hardware bodies (16) accommodates at least one adjusting pin (34), which can be moved along the y-axis located in the xy-plane, and at least one surface (36, 38) of the adjusting pin (34) which is inclined with respect to the y-axis interacts with at least one sliding pin (40, 42), the movement of which along the x-axis located in the xy-plane being restricted by the housing (12) accommodating the at least one hardware body (16), and so the hardware body (16) can be moved relative to the housing (12) in the x-direction by adjusting the adjustment pin (34). For the purpose of adjusting the hardware system in the y-direction at least one housing (14) and the hardware body (18) arranged in said housing have at least one sliding guide (44) extending along the y-axis, along which the hardware body can be moved relative to the housing (14) in the y-direction.
