It is possible to strengthen the screw threads by using low-strength materials such as aluminum and fiber-reinforced plastics.
HELICOIL is a spring-shaped coil made from wire that can be inserted into a tapped base material to reinforce the threads. Using bolts on base materials with low shear strength carries the risk of thread damage, but by using this product, the risk of having to completely replace the product during thread repair is prevented. Additionally, when fastening with iron bolts, the risk of destroying the threads is reduced, contributing to a decrease in defect rates, and an increase of approximately 40% in pull-out load is expected compared to threads without reinforcement. 【Features】 ■ Prevents the risk of complete product replacement during thread repair ■ Reduces the risk of thread destruction when fastening with iron bolts ■ Contributes to a reduction in defect rates ■ Expected increase of approximately 40% in pull-out load compared to threads without reinforcement ■ Can keep costs to a minimum ■ Supports automatic assembly *For more details, please refer to the PDF document or feel free to contact us.
