The precision lozenge profile thread slides continuously turn after turn.
The dimensional accuracy of the ISO thread complies with the DIN 13 6H standard, but for special needs it is possible to obtain the 4H class, and meets the requirements of international standards.
HELICOIL® Classic can also be used in the Screwlock version with screw braking area.
THREAD REINFORCEMENT
HELICOIL® Threads
High load capacity and precision. HELICOIL® thread inserts for robust screw joints.
FOR HIGH STRENGTH FIXINGS
HELICOIL® threads create resistant joints
HELICOIL® threads have proven themselves in practice for over 65 years. They are available in Free Running (standard) and Screwlock (with special braking system) versions. This technique can be used on almost any application.
STRENGTHS
Advantages of HELICOIL®
-
Long duration
The great elasticity of the HELICOIL® thread allows a uniform distribution of loads and tensions. Result: a higher quality screw joint than one without HELICOIL®.
-
Potential for lightweight construction
Ideal for lightweight constructions, HELICOIL® combines minimal bulk with high load capacity. This makes it possible to optimize the use of high-strength screws even in materials with low shear resistance. Fewer connection points and smaller screw size mean less material, less mounting space required and less weight.
-
Wear resistance
HELICOIL® threads are resistant to friction. The high surface quality of the internal thread made of austenitic chrome-nickel stainless steel ensures extremely strong threads. Furthermore, the thread features extremely low constant friction.
-
Reduced thread friction
HELICOIL® reduces thread friction and leakage gap. This means that during the torque-controlled tightening procedure, the variable preload force of the screw is adjusted more precisely, thus making better use of the elasticity limit of the screw.
-
Long duration
Anti-unscrewing safety. The polygonal thread of HELICOIL® Screwlock ensures strong friction which opposes any risk of unscrewing the screw. Therefore it is not necessary to secure the screwing with washers, lock nuts etc.
PROCEDURE AND PRINCIPLE
Very resistant thread
Thread reinforcement and repair are concepts inextricably linked to our HELICOIL® brand.
HELICOIL® can be used in particular on materials with low shear resistance such as aluminum or magnesium and aluminum alloys. In these applications, HELICOIL® threading inserts enable the production of high-precision threads that are extremely resistant to wear and heat. The internal thread does not wear out, even with frequent use.
