The present invention relates to a device to check a bolt and, more specifically, relates to a device to check a bolt by hitting a bolt on a railroad tie (700) to check if the bolt is loose; and check the loose bolt using a comparison of waveforms of the sound made by the impact. The device to check the bolt comprises: a body (100) having wheels engaged with the railroad to be movable; a checking unit (200) including a hammer plate (210) connected to the body (100) to hit a top surface of a connector (500) to fixate a rail (400) on the railroad tie (700); and an elastic unit connected to the top of the hammer plate (210); a control unit to receive the sound of hitting of the connector (500), and to determine if there is disorder; and an output unit (300) to display if there is disorder by a control of the control unit.
