How to Perform Shank Reduction for Extra-Long Screws?

Release time：2020-01-16 18:44 Browse：

To reduce the diameter (shrink the rod) of an extra-long screw, common methods include:

1. Turning/Lathing – Machining down the threaded portion to a smaller diameter.

2. Cold Drawing – Pulling the screw through a die to compress its diameter.

3. Grinding – Precision grinding to achieve a smooth, reduced diameter.

4. Swaging – Using pressure to taper or reduce the screw’s end.

Key Considerations:

• Maintain thread integrity and strength.

• Avoid overheating (especially in cold working).

• Ensure dimensional accuracy for proper fit.
