422J High-Durability Firing Pin 100 Pieces Per Pack Multi-Purpose Air Stapler

As an air stapler, the core advantage of our factory's tool lies in its versatility across all staple lengths: it is compatible with U-shaped staples ranging from 10-22mm, precisely matching applications from securing thin materials to fastening thick materials.
In terms of product durability, the steel magazine is hardened to resist collision and wear during long-term operation; the firing pin assembly and O-rings are made of high-durability materials, resulting in a much lower staple jamming rate than the industry average, and faster recoil response. The machine body is reinforced with 12.9-grade hex screws and features an overall heat treatment process, ensuring that the structure remains stable and resistant to deformation even during high-frequency continuous operation.
Its pressure range of 4-7 kgf/cm² allows for flexible force adjustment – ​​light pressure can securely fasten soft materials such as leather and fabric, preventing damage; heavy pressure can firmly fasten wood substrates, making it suitable for applications such as sofa upholstery, furniture frame assembly, fine wood veneer edging, and shoe material shaping. It is a highly reliable tool that balances precision work with mass production.
