Operating principle of 1/4" star tube from E4x25mm to E8x25mm standard DIN 3121 Yato:
1. Articulation:

• Star socket heads are designed with grooves that match the edges on the heads of bolts and screws. These grooves are arranged in a star shape, forming a sturdy mechanical joint.
• When you put the tube head on a bolt or screw, these grooves will hug the edges, creating friction between the two surfaces. This friction force is large enough to keep the tube head from slipping off the bolt or screw during the screwing process.

2. Power transmission:

• When force is applied to the handle of the tube, this force will be transmitted through the axis of the handle to the tip of the tube.
• Because the tip of the tube is tightly attached to the handle with a threaded joint, this force will be converted into tissue force acting on the grooves of the tip of the tube.

3. Make bolts and screws rotate:

• The tissue force acting on the grooves of the tube head will create friction on the edges of the bolts and screws. This friction force will cause bolts and screws to rotate in the direction of the applied force.
• The direction of rotation of bolts and screws depends on the direction of the handle. Turn clockwise to tighten, turn counterclockwise to loosen.

4. Influencing factors:

• The performance of star tips depends on many factors, including:
  • Material and hardness of tube heads and bolts and screws.
  • The friction force between the grooves of the tube head and the edges of the bolts and screws.
  • Tissue force acting on the handle of the tube.
  • Precision of joint between tube tip and handle.

5. Advantages:

• Star tube tips have many advantages compared to other types of tube tips, including:
  • Sturdy joints, limited slippage when screwing.
  • Easy to use, quick operation.
  • Suitable for many types of bolts and screws with star heads.
  • High durability, long service life.

6. Disadvantages:

• The star tip also has some disadvantages, including:
  • The price is higher than other types of tube tips.
  • Need a complete set of different tip sizes to meet usage needs.

How to use of 1/4" star tube from E4x25mm to E8x25mm standard DIN 3121 Yato:

1. Choose a star socket head of the appropriate size for the bolt and screw head.
2. Plug the end of the tube into the tube handle or wrench.
3. Place the tip of the tube on the head of the bolt or screw and turn clockwise to tighten or counterclockwise to loosen.

Notes when using 1/4" star tube from E4x25mm to E8x25mm standard DIN 3121 Yato:

• You should use a wrench with appropriate torque to avoid damaging bolts, screws or socket heads.
