ABSTRACT:
A locking device for preventing access to a bolt or stud-nut which secures an equipment to a base. The device comprises three parts: a block, a cover member and a lock body. In use, the bolt is put through a hole in the block and the equipment and is tightened down. The cover member is then fitted over the head of the bolt or stud-nut and the lock body is inserted in the block and locked by a key. This causes the lock to bear down on the cover member, preventing its removal. The device is compact and able to be used for a variety of applications where equipments are secured by bolts or stud-nuts.
