[0002] A bolt is a cylindrical, threaded fastener that connects with a nut or a threaded connection to a machine body, used to secure two or more parts together. In practice, conventional bolt and nut designs are often used. High-strength, wear-resistant bolts, made by melting materials in varying proportions, are used to replace ordinary bolts. However, existing technology has the following drawbacks: Existing high-strength, wear-resistant bolts can slip or even break during use due to excessive force. In light of this, this invention was specifically filed. Utility Model Content

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] like Figure 1-3As shown, the utility model relates to a high-strength hexagonal flange bolt, comprising a bolt head 1, a screw 4 and a flange 2, wherein the screw is located below the bolt head, and a flange is provided below the bolt head; a bolt head is provided below the flange; the screw comprises a column 4, an outer convex layer 41 is provided on the column, the outer convex layer is provided around the main body surface, and a thread 42 is provided on the outer convex layer; four guide grooves 5 are symmetrically provided on the outer convex layer, the guide grooves extend along the length direction of the outer convex layer, and the guide grooves cut through the threads on the surface of the stud; a special-shaped socket is provided in the middle of the top surface of the bolt head, and a special-shaped socket is provided on the top surface of the cap at the outside of the special-shaped socket The logo is recessed and marked 13. The special-shaped socket includes an upper socket 10 and a lower socket 11. The special-shaped socket extends into the interior of the screw. The upper socket contains four vertical surfaces 101, which are perpendicular to each other. An inward convex arc surface 102 is provided between adjacent vertical surfaces, and the height of the inward convex arc surface is 3.5mm to 6mm. An anti-counterfeiting groove 1 is provided on the top surface of the bolt head, and an anti-counterfeiting patch 8 is provided in the anti-counterfeiting groove.
