Beschreibung
Zusammenfassung:	The utility model discloses a bolt and engineering equipment comprising the same. The bolt comprises a screw cap part and a screw rod part which are mutually connected, wherein a crewing structure is formed on one side of the screw cap part, which is opposite to the screw rod part, the bolt further comprises a cap, and the cap is made of a nonmetallic material and is connected with a screw cap part so as to isolate the crewing structure of the screw cap part from the outside. The bolt provided by the utility model seals the hexagonal structure in the screw cap part by using the cap made of the nonmetallic material, so as to enable the screw cap part to be isolated from the outside, blockage caused by foreign objects, or rain water and air erosion leading to rust can be avoided, convenience in bolt dismounting can be improved, and equipment maintenance efficiency is improved.
