Abstract: A T-bolt locking device provides positive engagement of a T-bolt with a track as well as prevents disengagement from the track when loosening the T-bolt sufficiently to allow movement of an accessory along a slot in the track to a new position. Tightening the accessory onto the T-bolt secures flanges of the head of the T-bolt against an inner surface of the track while fixing the accessory to the track. The T-bolt locking device comprises opposing tabs configured to pass through the slot in the track and receive the flanges of the head of the T-bolt, whereby the locking device is in the engaged position, preventing rotation of the head of the T-bolt in relation to the tabs. When fastening the T-bolt and locking device, if the locking device does not seat against the track surface, this indicates that the T-bolt is under-rotated and not properly engaged with the track because the opposing tabs of the locking device are contacting the upper face of the T-bolt flange.
