<Bolt Hole> 【Product PR】 "MS Insert" is a female thread part designed to repair damaged bolt holes. An insert utilizing a special structure on the outer diameter thread is embedded into the bolt hole area for restoration. It is designed to be difficult to pull out and does not impose stress on the base material, making it suitable for installation in areas constantly exposed to vibration or at the ends. Compared to conventional products such as spring-type coils or self-tapping items, it improves precision and demonstrates groundbreaking effectiveness in terms of durability. Additionally, by pre-installing it in areas where bolts are frequently attached and detached, permanent measures can be implemented. 【Features】 ■ Difficult to pull out and does not impose stress on the base material ■ Ideal for permanent solutions for threaded holes ■ Can be used to strengthen and restore thread profiles ■ Enables installation at the ends → The design of the upward-facing thread works to attract the surrounding base material towards the center of the screw from all directions For more details, please contact us or download the catalog.

Company information
The mechanical stitch metal crack repair technology is a method that physically repairs metal cracks using special bolts and reinforcement plates (mechanical stitch method), which does not apply heat to the repair area, thus preventing thermal distortion in the crack repair (Mechanical Stitch method). In addition to metal crack repair, it also has the technology to regenerate damaged screw threads using repair inserts. Furthermore, since repairs can be performed on-site, it allows for reduced construction time and cost savings.
