Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, and more specifically, to a special-shaped bolt fastener. Background Art

[0002] Special-shaped bolts are a kind of non-standard fasteners. The main functions of special-shaped bolts and standard bolts are to fix two or more parts together. Special-shaped bolts are often used for some special parts and special occasions. Some special-shaped bolts can improve the efficiency of installing bolts or add additional functions. Traditional standard bolts are composed of screws and bolt heads. The main styles of bolt heads include hexagonal styles. However, traditional standard bolts lack waterproof function, and the waterproof plugs of installed bolts are easy to fall off. In outdoor occasions, rainwater will penetrate into the interior of the parts from the gap between the bolts and the parts, resulting in rust inside the parts, etc., which affects the airtightness of the parts to a certain extent. In order to solve the shortcomings of the existing technology, we propose a special-shaped bolt fastener. Utility Model Content
