The wire screw insert is a solution that forms the screw thread by tapping a pre-drilled hole with a dedicated tap and inserting the main body.
**Features** - Suitable not only for metal and plastic substrates but also for softer materials such as aluminum, magnesium, and titanium. - By using lightweight materials, it contributes to cost reduction in manufacturing while maintaining the strength of the screw threads. - Products are available that accommodate various specifications, including metric coarse and fine, Unified coarse and fine (UNC/UNF), British standards (BSW, BSC, BA, BSP), and American standards (NPT), covering a wide range of sizes from 2mm to 100mm. - There are two methods: free-running and screw-locking, and both can be selected according to the application from tangless types and types with tangs.

Applications/Examples of results
【Purpose】 ■ It is used to attach screws and bolts to soft materials. Directly screwing screws or bolts into soft materials can damage the base material, so after setting the screw insert, screws or bolts are inserted into the screw insert. ■ It can repair loose screw holes due to improper insertion of screws that do not match the screw hole diameter, distortion during installation, over-tightening of screws, or deformation of screw holes caused by rust and corrosion. ■ It can also be used when it is not possible to support the entire length of screws or bolts with thin base materials. Even if the screw insert protrudes from the bottom edge of the workpiece, screws or bolts can be screwed all the way into the screw insert.

■ Wire screw inserts with tang: 【Features】・This product has a "tang" that allows for tool gripping during insertion. ・By using wire screw inserts, the screw threads can be reinforced, extending the lifespan of the application. ・The insert shares the load across the bolt and the entire hole, allowing for a more even distribution of load and stress, thereby improving holding or pull-out resistance. ・Typically made by rolling SUS304 (18-8) steel wire into a diamond cross-section, there are also products made from materials such as Inconel, Nimonic 90, Nimonic 60, phosphor bronze, and SUS316.
