<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 difficult to pull out and does not impose a load 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 and self-tapping items, it improves accuracy and demonstrates groundbreaking effects 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 a load on the base material ■ Ideal for permanent measures for threaded holes ■ Can be used to reinforce and restore thread profiles ■ Enables installation at the ends → Designed with upward-facing thread profiles that draw 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 (mechanical stitch method) that physically repairs metal cracks using special bolts and reinforcement plates, and since it does not apply heat to the repair area, it does not cause 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 conducted on-site, it allows for reduced construction time and cost savings.
