Zusammenfassung:	The utility model provides a bolt for pylon, the bolt is including the head, polished rod and the screw rod that connect gradually, the cross -section of head is the rhombus, the polished rod includes: the first body of rod and connect respectively in two second bodies of rod at the both ends of the first body of rod, the diameter of the first body of rod is greater than the diameter of the secondbody of rod, just the diameter of the second body of rod is less than the path of screw rod, an at least cornerwise length of rhombus is greater than the big footpath of screw rod is and be greater than the diameter of the first body of rod. The utility model discloses a bolt for pylon can reduce the clearance between mounting hole and the polished rod with the help of the first body of rod to avoid the bolt to use the back crooked for a long time, perhaps reduce crooked degree at least, and the cross -section is compared the cross -section for the head of rhombus and for the circular shape head, is changeed by spaci
