【Product PR】 The "MS Insert" is a female threaded part designed to repair damaged bolt holes. It embeds an insert with a special structure applied to the outer diameter thread into the bolt hole area for restoration. It is difficult to pull out and does not put stress on the base material, making it suitable for installation in areas constantly exposed to vibrations or at the ends. Compared to conventional products such as spring-type coils and 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 stress the base material ■ Ideal for permanent measures for threaded holes ■ Can be used to reinforce and restore thread profiles ■ Enables installation at ends → Designed with upward-facing thread profiles that attract the surrounding base material towards the center of the screw from all directions For more details, please contact us or download the catalog.

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.
