The elastically durable friction-locking results in clamping torques that are comparable to the specifications of ISO 2320. These screw-locking torques meet the requirements of the technical delivery conditions for international standards. The clamping torques can also be individually adjusted as required for a specific application, e.g. for securing setting screws. HELICOIL® Classic Screwlock thread inserts should only be used with screws of higher strength classes (from 8.8).

The HELICOIL® Tangfree Screwlock has a clamping area that serves as a captive screw lock. The screw lock is achieved by one or more polygonal turns that have a clamping effect on the flanks of the installed screw. The elastically resilient frictional locking results in clamping torques comparable to the specifications of ISO 2320. These defined clamping torques meet requirements of the technical delivery conditions according to international standards.

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.

The coil thread insert with its precision-formed rhombic profile is free running turn by turn. This creates a true-to-gauge internal thread that can be used on both sides.

The dimensional stability of the ISO thread is compliant with DIN 13 6H, 4H for special requirements, and meets the requirements of international standards.

In addition, this thread insert also has a clamping area for captive screw locking. One or more polygonal turns have a clamping effect on the flanks of the installed screw. The defined clamping torques meet the requirements of international standards.

Just like the HELICOIL® Plus, the HELICOIL® Smart is provided with a special thread start to allow easier installation in a holding thread.

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.

With our HELICOIL® Cast thread inserts you can create threads in aluminium materials using the in-mould process. Generate wear-free, resilient threads in high-quality lightweight components.

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.

The advantages of the HELICOIL® Plus systems are particularly apparent in processing and tools, as they significantly reduce installation times.

The thread insert without tang. You do not need a driver tang to install these thread inserts. Thus, there is no need to break off and remove tangs.

The dimensional stability of the ISO thread complies with DIN 13 6H, with 4H for special requirements, and meets the requirements of international standards.

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.

This thread insert merges the advantages of the HELICOIL® Plus and the HELICOIL® Tangfree. There is a tang, but it does not have to be broken off and removed. The installation time is therefore reduced by approx. 20 %. Every thread of the thread insert with precision-formed, rhombic profile is free running. The result is a true-to-gauge internal thread including the last thread which is in every case threadable.

The HELICOIL® Tangfree Free Running can be set and inserted like a screw. Free running turn by turn, the HELICOIL® Tangfree Free Running thread insert is a true-to-gauge, internal thread that can be used on both sides for secure, high-strength screw joints.

Different weather conditions, permanent force effects through vibration and irregular capacity utilization significantly impact the individual components. These extreme influences pose a variety of challenges and requirements for the production of construction and agricultural machinery.

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®.

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.

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.
