LOCKTIX® The screw lock for vibration-proof screw connections

Simple advantages that speak for themselves:

  1. Only one washer to be installed
  2. Minimal washer height
  3. Shorter windings mean reduced weight and cost
  4. Can be used repeatedly; i.e. product is re-usable
  5. Also works in long holes
  6. No risk of confusion or mounting errors
  7. No hydrogen embrittlement
  8. Zinc-nickel plated
  9. Use in conjunction with screw rigidities 8.8; 10.9 and 12.9
  10. Optimum loosening turn lock at full or half preload force

Many of the alternative and even more expensive products currently on the market do not have the capabilities of Locktix!

These products frequently consist of two components positioned into place with an adhesive. Once the adhesive loses its stickiness (after being stored or due to aging or UV light exposure), the components, which are not symmetric, loosen and incorrect installation can no longer be ruled out.

You will not encounter this problem with Locktix, since it consists only of a single washer, which is always correctly positioned. It holds in place dependably – so your screw connection will not only be “firmer” but also more cost effective!

Locktix also secures screws tightly into painted, anodized and zinc coated surfaces as well as oily or greasy surfaces.
