Conventional column connection solutions often don't work for metal columns due to different material properties and their larger outer diameter. The following solution can be used to connect 2 metal columns:

• 0.53 mm to 0.53 mm (you have to order: 1x 980-03168, 2x 980-05636)
• 0.53 mm to 0.32 mm (you have to order: 1x 980-03168, 2x 980-05636)
• 0.32 mm to 0.32 mm (you have to order: 1x 980-03168, 2x 980-05636)
