SPIRALĂ METALICĂ

The HEICO-LOCK® Wedge Lock Nut is a re-usable one piece design that delivers high quality, user friendly bolt security without the need for seperate fasteners. 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 one piece design eliminates the risk of misuse Minimized risk of operating and production breakdowns caused by faulty bolted connections Easy handling especially in hard to reach locations Fixed permanently in the correct position Reduction of assembly time and effort Reduced complexity of the component due to less individual parts Easy, safe and fast installation even for non-specialist users Can be re-used Available from M6 – M27 in strength class 10 Also available with fine thread: M20x1.5 and M22x1.5

Even under extremes of vibration or dynamic loads, the HEICO-LOCK® Wedge Locking System provides maximum reliability. When the bolt is tightened, the external radial teeth of the HEICO-LOCK® Wedge Lock System 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 clamping force. Certified system for securing bolts, working at low and high preload levels Particularly suitable for dynamic loads – including when using lubricants Can be re-used Very easy to install and remove (wedge lock washers are supplied as a pre-assembled pair) Also suitable for high-tensile bolts of 8.8, 10.9 and 12.9 and their respective nuts Available in steel or stainless steel with narrow or wide bearing surfaces – other materials are available upon request Available from M3 – M76 and ¼” – 3” - custom sizes upon request

HEICO-TEC® Expansion Bolts are the perfect product solution for connecting large and rotating couplings - precise, reliable, and quickly assembled! Optimal alignment of components Adapts perfectly to the bores due to radial expansion No expensive and time-consuming reboring of holes or new fitted bolts Easy to handle – even for non-specialist users Quick assembly Reusable HEICO-TEC® Expansion Bolts are customized to your specific application and precisely tailored to your requirements. Whether you prefer the compact series of HEICO-TEC® Tension Nuts due to limiting constraints, or you wish to optimize the product lifespan of the bolt by using an elastically resilient HEICO-TEC® Reaction Nut, or want to protect your connections against self-loosening, the variety of options is nearly unlimited. We are also please to assist you with all questions related to corrosion protection, ensuring that your expansion bolts remain durable and reliable despite adverse environmental and weather influences. In this way, you ensure that your components stay safe and ready for long-term use. In cooperation with you, we will design the perfect solution for your application!
