In the vehicle manufacturing industry the use of light weight materials such as aluminum and magnesium is becoming increasingly common. Accordingly, demand is growing for more advanced tightening strategies and equipment, especially at low torques. Atlas Copco's QST34-20CT and QST34-8CT are a high end solution for the low-torque segment of fixtured tools.

The wide torque range of the spindle, down 20% of the rated torque, makes the QST34 suitable for large angle and yield tightening strategies. It also means that the same spindle type can be used at several stations in a line.  This offers major savings due to a reduction in the number of spare parts and shorter mean time to repair.

The new QST makes tricky bolt patterns a thing of the past.

Suitable joints

• Joints with M5 and M6 bolts
  
• Bolts made of aluminum or magnesium
  
• Joints where torque, Torque plus Angle and yield tightening strategies are used
  

Target applications

• Robot applications (stitching)
  
• Gearbox lines
  
• Sun roof applications
  
• Smaller engines like marine engines, snowmobiles and motor-cycles
