Description

Technical Field

[0001] The utility model relates to the technical field of hexagonal bolts, in particular to a hexagonal bolt with a flange surface capable of preventing thread slippage. Background Art

[0002] Flange bolts are integrated bolts consisting of a hexagonal head, a flange plate and a screw. They need to be matched with nuts to fasten parts connecting two through holes. Depending on the use position of the flange bolt, the size requirements of the plate are different. There are also flat bottoms and teeth. The teeth have an anti-slip effect. The existing flange surface hexagonal bolts may be directly exposed to the outside after tightening, causing water to enter the connection between the hexagonal bolt and the threaded hole from the bolt head, causing the hexagonal bolt to rust, which leads to the hexagonal bolt slipping when disassembled. For this reason, we propose a flange surface hexagonal bolt that can prevent slipping.

[0003] In order to solve the above technical problems, a Chinese patent with announcement number CN216842608U in the prior art discloses a flange-face hexagonal bolt with anti-slip thread, comprising a bolt head and a threaded rod, wherein the bolt head comprises a bolt head fitting portion connected to the threaded rod and a hexagonal end head, wherein the hexagonal end head comprises an outer hexagonal end head connected to the bolt head fitting portion, an inner hexagonal groove is provided on a side of the outer hexagonal end head away from the threaded rod, a cross groove is provided on the inner bottom of the inner hexagonal groove, and a waterproof protective cover is sleeved on the outer side of the bolt head fitting portion.

[0004] Although the above-mentioned prior art solution allows the waterproof cover to cover the exposed part of the threaded rod to prevent moisture from seeping in from the gap of the interface, one side of the waterproof cover is installed with a blocking structure or a positioning structure. After the waterproof cover is installed, it is very easy to be flipped up on one side due to collision or improper connection. Gaps appear at the connection, and moisture enters therein to cause the threaded rod to rust, thereby affecting its service life. Utility Model Content
