<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 regeneration. It is difficult to pull out and does not put stress on the base material, making it suitable for areas constantly exposed to vibrations or at the ends. Compared to conventional products such as spring-type coils or self-tapping items, it improves precision and demonstrates groundbreaking effects in terms of durability. Additionally, by applying it in areas where bolts are frequently attached and detached, permanent measures can be established. 【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 recover thread profiles ■ Enables application 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.
