Staple Product Classification

Based on the nail type, they are categorized into three series: J-type, K-type, and N-type. J-type corresponds to standard straight staples, K-type is thicker, and N-type is narrower. Each model is distinguished by a first letter code. For example, J4215 represents a J-type staple with a 15mm foot length and a 42mm width. This coding system, along with F-type straight staples and ST-type steel staples, forms a standardized sequence for pneumatic nailer consumables.
