Product Description

Bolt

,

Bolt: A cylindrical threaded fastener used with nuts as an essential mechanical component. It consists of a head and a screw (cylindrical body with external threads) that pairs with a nut to securely join two parts through holes. This connection type is known as a bolted connection.If the nut is unscrewed from the bolt, the two parts can be separated, making this a detachable connection.

Applications

Our bolts find their place in a myriad of applications, including electronic devices, mechanical assemblies, digital products, power systems, and electromechanical equipment. They are also invaluable in ships, vehicles, hydraulic projects, and even chemical experiments.

Moreover, bolts are indispensable across various sectors. Precision bolts are vital for digital products, such as DVDs, while micro bolts are essential for cameras, glasses, clocks, and electronics. General bolts are used in televisions, electrical appliances, musical instruments, and furniture. In engineering and construction, especially for bridges, large bolts and nuts are crucial. Transportation vehicles, including airplanes, trams, and cars, utilize both large and small bolts. Bolts are indeed the backbone of industries, maintaining their significance as long as industry exists.Bolts are essential in many fields, from precision to large-scale engineering projects, playing a pivotal role in the industrial world.

Key Configurations

Based on the connection's force method, bolts are categorized into ordinary and reamed holes. According to the head shape,they are divided into hexagonal heads, round heads, square heads, and counterstops. Hexagonal heads are the most prevalent. Countersinks are typically used for connections requiring flush surfaces. U-bolts, known for their U-shape, are non-standard components used to secure tubular objects or sheets, like water pipes or car leaf springs. Named for their resemblance to a rider on a horse, these bolts have threads at both ends to work with nuts, and are available in full or partial thread lengths.They are specifically designed to fix tubular objects or sheets, such as water pipes or car leaf springs, effectively securing them as a rider does to a horse. Thread length options include full and partial threads.

Bolt Detection Excellence

Bolt inspection is meticulously executed using both manual and machine methodologies. Manual inspection, though traditional, remains effective and a highly reliable approach. To significantly reduce the outflow of defective products, skilled personnel in manufacturing enterprises conduct thorough visual inspections of products destined for packaging or shipment, diligently identifying and eliminating defects such as thread damage, mixed materials, and rust.

An advanced alternative is the fully automated machine inspection, predominantly employing magnetic particle testing. This sophisticated process leverages the interaction between the leakage magnetic field at bolt defects and magnetic powder. The disparity in magnetic permeability between potential defects—such as cracks, slag inclusions, and mixed materials—and the steel results in a distorted magnetic field upon magnetization, causing partial magnetic flux leakage on the workpiece surface. This leakage magnetic field attracts magnetic powder to the defect location, forming identifiable magnetic indications. Under optimal lighting, the precise position and nature of these defects are revealed by analyzing the magnetic powder accumulations, effectively facilitating the elimination of defective products.
