Damage and loosening prevention for aluminum and non-ferrous materials, thread reinforcement (insert nut).
HELICOIL、Kobsert
<Compatible with M3 to M120> Demonstrates high airtightness and corrosion resistance for metal materials with low shear strength, such as aluminum die-cast and magnesium parts!
We would like to introduce the thread reinforcement (insert nuts) for non-ferrous materials, including aluminum die casting, handled by our company, Berhof. 【Product Details】 ◎ Helicoil: For aluminum extrusions Using bolts on a base material with low shear strength poses a risk of thread damage. However, by using this product, the risk of having to completely replace the product during thread repair is prevented. Additionally, the risk of damaging the threads when fastening with iron bolts is reduced, contributing to a lower defect rate. An approximate 40% increase in pull-out load is expected compared to unreinforced threads. ⇒ It is possible to keep costs to a minimum. ◎ Kobsert: For aluminum and magnesium die casting - Used for thread reinforcement and repair of damaged threads - Mechanically secured without the need for additional fixing pins, washers, or chemical adhesives - Easy to install for anyone - Available with a seal ring for even higher airtightness An approximate 40% increase in pull-out load is expected compared to unreinforced threads. ⇒ It is possible to extend product life and achieve high cost-effectiveness. *For more details, please refer to the PDF document or feel free to contact us.
