<Bolt Hole> 【Product PR】 "MS Insert" is a female screw 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 a load on the base material, making it suitable for installation in areas that are 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 effects in terms of durability. Additionally, by pre-installing it in areas where bolts are frequently attached and detached, permanent solutions can be achieved. 【Features】 ■ Difficult to pull out and does not impose a load on the base material ■ Ideal for permanent solutions for screw holes ■ Can be used to strengthen and restore thread profiles ■ Enables installation at the ends → The upward design of the 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.
