HEICO Befestigungstechnik GmbH

HEICO-LOCK® ring lock washers provide high-quality, user-friendly bolt securing for the most demanding of applications and are ideal for repeated use. The ring locking system guarantees that the two wedge lock washers are always fastened in the correct position with the wedge shaped cams on the inside and the radial teeth on the outside. This means that the bolt locking system is always easy, safe and quick to install, even for non-specialist users.

The HEICO-LOCK® wedge lock nut provides a high-quality, user-friendly bolt securing system for the most demanding of applications and is ideal for repeated use. The captive and rotary combination of the nut and the original HEICO-LOCK® wedge lock washers makes securing your bolted joints more efficient, effective and easier even under the most extreme vibrations and dynamic loads.

The HEICO-LOCK® wedge locking system delivers high quality anti-vibration security for the most demanding of bolted joint applications. Even under extremes of vibration or dynamic loads, HEICO-LOCK® wedge lock washers provide maximum reliability. When the bolt is tightened, the external radial teeth of the HEICO-LOCK® wedge lock washers embed themselves in an interlocking fashion with the respective mating surface. If the securing system is subject to dynamic stress, movement is only possible between the internal washer surfaces. This results in an increase in the preload force.

For a secure joint with a HEICO-TEC® tension nut, no electric, hydraulic, or pneumatic tools are needed. All you need is a torque wrench. The HEICO-TEC® tension nut is unique in the fact that the pretension force of the large main thread is distributed to many smaller pressure bolts. Because the pressure bolts are smaller, a conventional torque wrench can be used to achieve the correct pretension force. This eliminates the need for complex, bulky, or heavy tools and makes securing large bolted joints more convenient and easy.
