The Fastfit is truly a one piece - one step connector, this new generation of knockdown connector continues to incorporate Zipbolts Patented gear drive technology to achieve a new approach to furniture/cabinet assembly. It is released coinciding with the world wide trend towards the use of CNC Routers or Nesting machines and the result is fast and easy manufacturing saving time and money. Fastfit uses a unique mechanism to conceal the thread within the dowel section and then using the gear drive exits the thread to bite directly into the wall of the hole producing a very strong anchor.
