Five-claw buckle is a kind of four-claw buckle, five-claw buckle is usually composed of three parts: mother buckle (B piece), sub-buckle (C piece), bottom buckle (D piece) and face buckle (A piece). A piece can be changed at will, and the specification of five claws is determined by BCD.

Five claw buckle can be divided into: hollow five claw buckle, wrapped surface five claw buckle, pearlescent five claw buckle, lacquer five claw buckle, mixed pattern five claw buckle, nine claw buckle, eight claw buckle. 

In the installation of five-claw buckle, the five-claw buttoning machine is provided to customers free of charge, and the hand beer buttoning machine is used to install with the corresponding mold. it is suitable for batch installation in small factories and has high efficiency.
For personal use, you can also use manual five-claw buckle installation tools to use hammer hand to install, the success rate is high.
It can also be installed by hand with manual four-buckle installation tool and base with hammer, but the success rate is low and needs to be practiced many times.
Manual installation method is inefficient, suitable for a small number of manual enthusiasts to install.

Five-claw buckle is mainly suitable for woolen thin clothing material, flexible clothing material, non-flexible clothing material, such as: Western-style pajamas, knitted underwear and so on. 

The main material of the five-claw buckle is copper (62 copper, 65 copper, 68 copper), which makes use of the elastic characteristics of the brass belt to realize the function of riveting and fastening. the product needs to be fixed on the clothing by tapping the mold and sewing nail. 

As five-claw buttons are mostly used in children‘s clothing, perhaps outdoor products, EU countries are extremely cautious about environmental protection and chemicals that endanger children (mainly direct contact with the skin) and have developed corresponding legal standards. 

Therefore, five-claw button electroplating is generally non-Lat environmental protection treatment. 

All adopt Shanghai Chinalco high quality and high precision belt environmental protection copper, the product size control is very strict, the deviation is controlled within 5um, according to the influence of different electroplating colors on the product performance, the product eight-valve size is adjusted. 

In order to ensure that the tensile force, destructive force, patting force test of the product is qualified and stable, the fastening sound is clear and crisp, the opening force is stable, there are no high and low claws, the environmental protection test can reach more than eight grades, the product has been strictly inspected and packed in fine cartons before leaving the factory.
