Since 1900 the family owned HEICO group has offered its customers reliable and high-quality solutions in the field of fastening technology and can thus draw on extensive technical know-how.
Starting with the production and distribution of nails, mainly for the furniture industry, the product portfolio of HEICO has continuously expanded over the years. At the beginning of the 1990s, HEICO started production of customer-specific, drawing-related cold forged parts. These parts are mainly distributed to the automotive industry with customers including Audi, VW and BMW. With management of the company passing to the fourth generation of the family in 2006 the product range was significantly enhanced again by the HEICO-LOCK® product group and the HEICO-TEC® Tension Nut.
The highest degree of vertical integration through in-house tool and machine construction, in-house heat treatments and surface refinements, as well as a continuous process control system, have always characterized the quality philosophy of the HEICO group.
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
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.
