VÖLKEL Thread Repair Kit V-COIL notch M 5 x 0.8 – 1.5 D

Features and applications

This repair kit is intended for restoring a damaged M 5 X 0.8 internal thread while retaining the original screw size. The decisive selection points are thread designation, repair system type, insert length, and the application environment.

Before starting, confirm that the component has enough material for the repair process and that the original thread size is known.

Applications

• for repairing damaged internal threads with the original designation M 5 X 0.8
• for V-COIL repair workflows using coordinated preparation and insert installation steps
• for maintenance, repair workshop, field service, and mechanical engineering use for selecting a complete repair route by thread size and insert length

Benefits

• Kit format supports a coordinated thread repair workflow for one original thread size.
• Thread designation M 5 X 0.8 keeps repair selection tied to the damaged internal thread.
• Insert length in the title supports repair planning where the length is specified.
• Process structure helps separate drilling, STI tapping, insert installation, and final checking.

Application limits

• A repair kit still requires correct sequence and alignment, so do not skip component checks before starting the repair.
