TIFAS LockBolt

TIFAS® LockBolt standard system

Lockbolts are ideal for permanently and securely fastening two parts together so that they will never detach, even when subjected to preload or dynamic load.

TIFAS® LockBolt is the standard system offered by Titgemeyer GmbH & Co. KG and comprises a pin as well as three versions of collar: standard, low-profile or flanged. The components marry perfectly with each other to ensure correct assembly and a reliable fixing. Even when subjected to vibrations, the applied clamp force remains constant. As a positive locking device that fastens permanently with the bolt, the collar is impossible to remove. The expertise that we have acquired through manufacturing these components in-house means we can also offer bespoke solutions for customers, subject to feasibility.

 

Installation steps

  1. Select lockbolts based on the specified requirements as well as the clamping thicknesses available on-site (sum total of all wall thick- nesses to be installed)
  2. Select the installation tool, incl. pulling head that matches the lock- bolts to be installed (for details, see “Overview – Lockbolts” in the “Tools for Lockbolts” catalogue)
  3. Insert the bolt into both through- holes on the component and, with the chamfer aligned to the end of the bolt, slide the collar over the pin. (Fig. 1)
  4. Fully press the installation tool with attached pulling head against the collar while securing the pin in place from the opposite side to prevent it from being poked out. (Fig. 2)
  5. Press the trigger on the tool. The jaws then grip into the grooves on the pin tail and tug at the pin. The pulling head sleeve presses up against the components and the resulting clamp force pushes them together. (Fig. 3)
  6. As the tool continues to pull, the pulling head sleeve slides over the collar. (Fig. 4) This reduces the external diameter of the collar. The compressed material slides into the locking grooves of the bolt to form the desired positive fit. As the front side of the sleeve elonga- tes, it is pushed up against the component to create the desired preload where the parts connect.
  7. The tool will continue to pull until the lockbolt’s breakload is achie- ved causing the tip of the bolt (pul- ling head) to snap off at the break- neck groove. Installation is now complete. (Fig. 5)
