PROBLEM TO BE SOLVED: To provide a bolt for locking capable of preventing an outsider from removing it by using it in combination with a commercially available padlock. SOLUTION: This bolt 1 for locking is inserted into a bolt hole 33 in a recessed part 32 of an object 31 to be fastened, is fastened by a box wrench, and is screw-fitted into a bolt hole 35 in a fixing member 34. This bolt 1 is composed of a main body 2 and a locking pin 5 capable of rotating around a shaft of the main body 2 and moving freely and vertically. The main body 2 is composed of a head part 3 and a shaft part 4 and has a guide hole 6, a receiving hole 7, and a through hole 8. The locking pin 5 is composed of a head part 10, a shaft part 11, and a coming-off prevention part 12. The head part 10 has a locking hole 14 and is received into the receiving hole 7 in the main body 2. After fastening the object 31 onto the fixing member 34 by the bolt 1 for locking, a shackle 22 of the padlock 21 is inserted into the locking hole 14 of the locking pin 5 protruding from the head part 3 to lock, thereby preventing the box wrench from being engaged with the head part 3.
