Hexagon socket head cap screw fastener

Abstract

The invention belongs to the technical field of screw fasteners, and particularly relates to a hexagon socket head cap screw fastener. The hexagon socket head cap screw fastener comprises a screw mainshaft, a connecting block is arranged at the upper end of the screw main shaft, a limiting plate is arranged on one side of the connecting block, a connecting clamping groove is formed in the outer surface of the lower end of the limiting plate, an extension plate is arranged in the connecting clamping groove, a fixed screw hole is formed in the outer surface of the upper end of the limiting plate in a penetrating manner, a rotating stud is arranged on the inner side of the fixed screw hole, a bearing plate is arranged at the upper end of the rotating stud, a connecting square groove is formed in the outer surface of the upper end of the connecting block, a fastener fixing block is arranged above a connecting square groove in the upper end of the connecting block, and a connecting squareblock is arranged on the inner side of a connecting square groove in the outer surface of the lower end of the fastener fixing block. The hexagon socket head cap screw fastener is more convenient to use, the service life of the hexagon socket head cap screw fastener can be prolonged, and better use prospects are brought.

Description

technical field [0001] The invention belongs to the technical field of screw fasteners, in particular to an inner hexagonal screw fastener. Background technique [0002] Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc., in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments All kinds of fasteners can be seen on the , chemical industry, instruments and supplies, etc., which are the most widely used mechanical basic parts. It is characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization, and generalization. Therefore, some people also refer to a class of fasteners with existing national standards as standard fasteners, or simply as s...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, it is easy to solve the phenomenon of wire slipping during disassembly and installation, which leads to time-consuming and laborious disassembly. At the same time, after internal corrosion occurs, lubricating oil is usually applied on the surface for lubrication, but the lubricating oil cannot enter the interior, resulting in The infiltration effect of the rusted part is poor, and the disassembly process is still time-consuming and laborious, and it is very easy to cause damage to the hexagon socket screw fastener and the problem of short service life. The invention proposes a hexagon socket screw fastener
