Thread chaser Art-Pol M18x2.0 mm, model 47136 — external metric thread repair tool

Art-Pol model 47136 is a thread chaser for external metric threads sized M18x2.0 mm. It is designed to restore, clean, and repair damaged or corroded external threads on bolts, studs and other cylindrical parts. The tool restores the original thread profile and thread fit so that nuts and mating parts can be reassembled with correct engagement. This chaser is intended for manual or light power-assisted use in maintenance, automotive repair and general metalworking environments where M18x2.0 external threads require accurate restoration.

Advantages

The thread chaser is manufactured to match the standard M18x2.0 metric thread form, providing precise correction of thread pitch and profile without removing significant material from the parent thread. Its geometry is aimed at cleaning rust, paint and debris while reforming deformed crests and roots, enabling improved mating with nuts and threaded components. The compact design allows access to exposed thread lengths and facilitates controlled manual or low-speed powered operation.

Suitable for

• Repairing damaged or corroded M18x2.0 external threads on bolts and studs
• Maintenance and service work in automotive and industrial equipment
• Cleaning threads prior to assembly or inspection
• Metalworking tasks requiring restoration of thread fit without full replacement of parts

Key specifications

• Thread size: M18 x 2.0 mm (external metric)
• Function: external thread chasing and repair
• Compatibility: designed for standard metric M18x2.0 thread profile and pitch
• Application method: manual use or low-speed power-assisted operation
• Typical materials: steel, stainless steel, plated fasteners and similar metals

How to use

Secure the workpiece or fastener to prevent rotation and ensure stable access to the damaged thread. Align the thread chaser with the thread axis and start engagement by hand, applying steady axial pressure while turning the tool in the correct thread direction. Work slowly through the damaged section, reversing periodically to clear debris and avoid further deformation. After reforming the thread, clean chips and residue with a brush or compressed air and verify fit with a mating nut or gauge. For heavily corroded threads consider initial rust removal and lubrication to reduce resistance during chasing.

Usage recommendations

Use appropriate personal protective equipment such as gloves and eye protection. Avoid high-speed power tools that may overheat or remove excessive material. Apply light cutting oil or lubricant when working on corroded or hardened surfaces to improve tool life and thread finish.
