There are many names for bolts. Each person's name may be different. Some people call them screws. Some people call them stud bolts. Some call them fasteners. Although there are so many names, the meaning is the same. They are all bolts. Bolts are a common term for fasteners. Bolts are tools that use the physics and mathematics of an object's beveled circular rotation and friction to progressively fasten mechanical components.
Bolts are indispensable in everyday life and industrial manufacturing. Bolts are also called industrial rice. The use of bolts is widely seen. Bolt applications include: electronic products, mechanical products, digital products, electrical equipment, mechanical and electrical products. Bolts are also used in ships, vehicles, hydraulic engineering, and even chemical experiments. Anyway, bolts are used in many places. Special precision bolts used in digital products. DVDs, micro bolts for cameras, eyeglasses, watches, electronics, etc.; Non-Standard Bolts for TVs, electrical products, musical instruments, furniture, etc.; and large bolts and nuts for engineering, construction, and bridges; transportation equipment, airplanes, trams, automobiles. Etc. are used for size bolts. Bolts have an important mission in the industry. As long as there is industry on the earth, the function of bolts is always important.

Bolt detection is divided into two types, artificial and machine. Labor is the most primitive and most commonly used consistent detection method. In order to minimize the outflow of defective products, the general production company personnel conduct inspections by visually treating the packaged or shipped products to eliminate defective products (bad including dental injuries, mixed materials, rust, etc.).

Another way is automatic detection of the machine, mainly magnetic particle inspection. Magnetic particle flaw detection is the use of the interaction between the leakage magnetic field at the bolt defect and the magnetic powder, and the magnetic permeability and the permeability of the steel against the possible defects of the bolt (such as cracks, slag inclusions, mixed materials, etc.). These materials are discontinuous after magnetization. The magnetic field at the place will undergo a catastrophic change, forming a leakage magnetic field at the part of the magnetic flux leaking at the surface of the work piece, thereby attracting the magnetic powder to form a magnetic powder accumulation at the defect—a magnetic mark. Under appropriate lighting conditions, the position and shape of the defect will be revealed. The accumulation of these magnetic particles is observed and explained, and the purpose of rejecting defective products has been achieved.
