The HEICO-LOCK® HLK-Washers offer high quality anti-vibration security for HV sets according to DIN EN 14399-4 and DIN EN 14399-8. Even under extremes of vibration or severe dynamic loads in steel construction the HEICO-LOCK® HLK-Washers, which are approved by the German Institute for Structural Engineering (DIBt), provide maximum reliability. Due to the increased under head radius of HV bolts, the HEICO-LOCK® HLK-Washers are chamfered on the internal diameter to ensure optimal surface contact while tightening. Designed to secure HV sets according to DIN EN 14399-4 and DIN EN 14399-8 Replacing washers according to DIN EN 14399-6 Can be used for bolted connections of cat. A to E according to DIN EN 1993-1-8, a. o. suitable for slip-resistant connections Certified construction product (certificate of conformity) Approved for use by General Building Supervisory Authority (DIBt) Approval No Z-14.4-702 Approved for railway-specific applications (EBA approval) Very easy to install and remove (HLK-washers are supplied as a pre-assembled pair) The double chamfer also ensures that the HEICO-LOCK® HLK-Washers cannot be applied incorrectly, so avoiding operator error High corrosion resistance provided by use of a zinc-flake coating Available for HV sets from M12 up to M36

As with the other HEICO-TEC® mechanical tensioning products, the new HEICO-TEC® Tension Bolts are based on the same functional principle: taking a large bolted joint’s hard-to-manage main thread preload requirement and dividing it into many smaller, easier-to-manage force requirements. The HEICO-TEC® Tension Bolt's key advantages are accuracy, simplicity, reliability and safety. For example, a worker can tighten/loosen HEICO-TEC® Tension Bolts with simple hand tools instead of other costly and complicated tensioning methods. HEICO-TEC® Tension Bolts are specifically designed for applications with tight spaces. Compared to a conventional stud + hex nut bolted joint design, the solid, one-piece HEICO-TEC® Tension Bolt requires much less outside diameter and head height space allowances. This one-piece design further simplifies operations and logistics in doing away with the traditional two-piece stud + nut arrangement. As with the HEICO-TEC® Tension Nut, the HEICO-TEC® Tension Bolt creates torsion-free preloads in the main bolt avoiding the potential for thread damage. Wherever customers face tight installation spaces or require a single, easy-to-install tensioning device, HEICO-TEC® Tension Bolts provide the best solution. We can offer our HEICO-TEC® Tension Bolts in strength class 8.8 as a direct replacement for conventional bolts of the same strength class in the dimension range of M20-M100. HEICO can also satisfy specific customer requests with imperial/inch sizes, unique designs, higher strength classes or other special requirements.

The HEICO-TEC® Compact Series is mainly designed to be used in extraordinary confined spaces, as well in axial or radial direction, or if a comparably moderate preload level needs to be generated in relation to the classic, high-strength Tension Nut Series (Strength Class 8 and 10). The aim is to realize the best out of the available space and the maximum preload force that can be achieved. The standard range of dimensions is M20 - M160 Available in bare as well as zinc flake coated design Other dimensions, coating systems or materials are available on request
