Material: Blackened hexagon socket bolts with half thread are usually made of carbon steel as the main material. Carbon steel is an iron-carbon alloy with a low carbon content. It has good mechanical properties, such as high strength and toughness, can withstand certain tensile, shear and torsion forces, and has a relatively low cost, which makes it widely used in many common mechanical connection scenarios.
Surface treatment - blackening: The surface of this bolt is blackened. Blackening is a chemical oxidation treatment process that improves its surface properties by forming a black oxide film on the surface of the bolt. The main component of this oxide film is ferroferric oxide, which can prevent the bolt from rusting to a certain extent, improve its wear resistance, and also make the appearance of the bolt more uniform and beautiful. However, compared with some other surface treatment methods (such as galvanizing, nickel plating, etc.), the anti-rust ability of blackening treatment is relatively weak, and additional protective measures may be required in high humidity or highly corrosive environments.
Machinery manufacturing: It is widely used in ordinary mechanical processing equipment, agricultural machinery, woodworking machinery and other fields. For example, in the installation of machine tool guardrails, the connection of agricultural machinery shells, and the fixing of woodworking machinery knives, it is used to connect non-critical parts and exert its good mechanical properties and basic anti-rust ability.
Automotive industry: It is used in the connection of automobile interior parts, the fixing of non-critical brackets and other parts. Such as partial fixing of car seats, installation of storage boxes in the car, etc., it can meet the connection needs of automobile parts during normal driving. At the same time, considering the cost factor, blackened hexagon socket bolts with half threads are a more appropriate choice.
Electrical equipment assembly: It is used in the internal structure connection of some electrical equipment that does not have particularly high requirements on appearance. For example, the casing of ordinary TV sets and the chassis connection of small electrical appliances can be precisely connected using its semi-threaded structure, and its rust and wear resistance can also meet the requirements in general indoor environments.
Good mechanical properties: Due to the use of carbon steel, blackened hexagon socket bolts with half thread have good strength and toughness. In normal mechanical connections, it can withstand certain working loads, such as in the connection of the shells of some ordinary machine tools and the connection of non-critical parts of automobile parts, which can ensure the stability and reliability of the connection.
Certain anti-rust and wear resistance: Although the anti-rust ability of blackening treatment is limited, it can provide certain anti-rust protection in general indoor environments or mildly corrosive environments. At the same time, the oxide film formed by blackening can also enhance the wear resistance of the bolts and reduce the surface damage caused by friction during use.

What is an Allen bolt called?
An Allen bolt is also called a hex socket bolt or socket screw.
Why are Allen bolts used?
Allen bolts are used because they provide a secure, tamper-resistant fastening, and the hexagonal socket allows for better torque distribution. This makes them ideal for applications where space is limited, as they can be tightened or loosened in confined areas using an Allen key. They're commonly used in machinery, furniture, bicycles, and automotive parts.
How many types of Allen bolts are there?
There are several types of Allen bolts:Standard Allen Bolt、Button Head Allen Bolt、Flat Head Allen Bolt、Socket Cap Bolt、Set Screw (Grub Screw).
