Description

Small-sized hexagonal screw

Technical Field

The utility model relates to the technical field of hexagonal screws, in particular to a small-sized hexagonal screw.

Background

Hexagonal screws are a common type of threaded connection fastener, the head of which is hexagonal. Hexagonal screws are typically made of metallic materials, such as steel, stainless steel, copper, etc., and there are some special applications in which hexagonal screws made of plastic materials are used. Hexagonal screws are a very important fastener and have wide application in various fields and industries. They are used to connect, secure and support various components to ensure stability and safety of equipment and structures. Hexagonal screws are indispensable for automobiles, aviation, machinery, construction, and electronic devices.

Hexagonal screws have some unique advantages over other types of screws. First, the six corners of the hex screw head provide better rotational control for easier tightening and loosening. Second, hex screws typically employ socket configurations that can be operated using a wrench, spanner or wrench-like tool, providing greater torque output and higher work efficiency. In addition, the hexagonal shape of the hexagonal screw head also provides better force transfer and slip resistance. The design can reduce the abrasion and damage of the screw head, thereby prolonging the service life of the hexagonal screw. Moreover, hex screws generally have greater tensile and torsional strength, making the connection stronger and more reliable. The hexagonal screw has various specifications and dimensions to be selected to adapt to different requirements and application situations. Hexagonal screws of different materials, different pitches and different diameters can be selected as required. In addition, there are special types of hexagonal screws, such as hexagonal screws with sealing washers, hexagonal screws with locking devices, etc., to meet specific engineering requirements.

In summary, hex screws are a common and important threaded connection fastener with a special design of six corners. They play an important role in various industries and fields, providing a stable, safe and reliable connection. Whether in mechanical assembly, building construction or other engineering fields, the hexagonal screw is an indispensable instrument, but current hexagonal screw has flat head and tip two kinds, can't possess the characteristics of flat head and tip simultaneously on a screw to reduced hexagonal screw's practicality, for this, we propose a small-size hexagonal screw.
