日本KATO无尾螺纹护套是在普通螺纹护套的基础上开发研制的新型螺纹护套产品，克服传统螺纹护套安装柄及安装效率低的缺点，传统螺纹护套安装柄开槽部位不能控制精确，造成尾部不易折断或过易折断的现象，去柄时尾端易突起，影响螺纹旋入，严重影响产品质量，尾部去除后不易清理，易造成滞留，严重时会影响整个产品的质量。
同时传统的钢丝螺套在安装去柄时严重影响生产效率，安装较慢。无尾钢丝螺套采用螺纹旋转挂接式安装工具，充分考虑了安装的效率，安装不用去柄，无方向性。
无尾钢丝螺套的优点
◆KATO无尾钢丝螺套做为目前世界上先进的无安装柄钢丝螺套，具有诸多的优点，最主要就是安装方便，无方向性、安装便利，省去普通有尾钢丝螺套去除安装柄的繁琐环节，节省了时间，提高效率！
◆无尾钢丝螺套安装工具齐全，包括气动、电动工具、批量安装的配套工具支架等，适合大批量的安装使用，对提高工作效率有非常大的帮助！
KATO Tangless inserts give you all the benefits, features and performance of conventional tanged inserts. In fact, KATO Tangless inserts are identical in form fit and function to conventional tanged inserts. The only thing missing from KATO Tangless inserts are the tangs!
Here is where Tangless CoilThread Inserts stand out from all other helically-coiled inserts. Instead of a tang, tangless inserts feature a unique, ramped driving notch on the inside diameter of the first coil on each end of the insert (see diagram below). To drive the insert we developed an innovative installation tool with a patented, internal, spring -loaded pawl located at the tip of the tools mandrel. During Installation, this hooked pawl locks into the Insert Driving Notch and rotates the insert into the tapped hole. The pawl then retracts into the mandrel to allow the tool to back out of the installed insert.

The spring-loaded pawl within the installation tool engages the driving notch to install the insert. The chamfered ends of the insert allow the insert to smoothly enter the tapped hole.

Once the insert is driven to the proper depth, the installation tool automatically reverses rotation. The pawl slides back into the tool's recess as the mandrel unscrews from the installed insert
