NORMECO wobble adapter is a small but very useful accessory that adds controlled angular flexibility between your automatic tightening spindles and a socket.  

The micro-wobble universal joint for automated tightening systems (also referred to as a micro-damping universal joint or precision floating universal joint) is a high-precision floating transmission component installed between the servo tightening spindle and the socket.

 Key Features

1. Controlled Angle Movement

• Allows slight misalignment without losing engagement (around 5%) 

• Ideal for tight or partially obstructed spaces

2. High Torque Efficiency

• Transfers torque more directly than a universal joint

• Less energy loss and vibration

3. Compact Design

• Shorter and stronger than U-joints

• Better for confined environments

4. Drive Conversion

• Often used to convert:

• Square drive → square drive (e.g., 3/8" → 3/8")

  
  

  

  
  

Normeco offers standard models in 3/8", 1/2", and 3/4" drive sizes, compatible with the standard sockets listed in the product catalog.
