Thread reinforcement
Load capacity and precision at the highest stage. HELICOIL® thread inserts for strong screw joints.
For high-strength fastenings
HELICOIL® thread inserts have been reliable in practice for over 65 years. They are available in Free Running and Screwlock versions. There is virtually no task that this thread technology cannot handle.
Plus factors
The elastic properties of the HELICOIL® thread insert distribute load and tension uniformly. Result: A higher-quality screw joint compared to a screw joint without HELICOIL®.
Perfect for lightweight construction, HELICOIL® combines minimum spatial requirements with high load capacity. You can use high-strength screws optimally in low shear strength materials. Fewer connection points and reduced screw dimensions result in less material, reduced install space and lower weight.
HELICOIL® thread inserts are abrasion-resistant. The high surface quality of the rolled internal thread made of austenitic chrome-nickel steel ensures a high-strength thread. Moreover, this thread has a constant, extremely low thread friction torque.
HELICOIL® reduces thread fiction and its scatter range. This means that for a torque-controlled screw tightening application, the screw preload force can be adjusted more precisely, i.e. the yield point of the screw is utilized more efficiently.
No self-loosening. The polygonal twist of the HELICOIL® Screwlock results in a high friction locking capacity and thus a captive screw lock. Additional locking of the joint using split pins, wires or washers is not necessary.
Method and principle
Thread reinforcement and thread repair are terms that are inseparably connected with our HELICOIL® brand.
Use HELICOIL® wherever low shear strength materials – such as aluminium or aluminium-magnesium alloys – are used. In these applications HELICOIL® thread inserts generate heat-resistant, wear-resistant and high-strength thread of the highest precision. No internal thread wear, even with frequent use.
