Thread chaser FANAR M5 model N1-111001-0050

The FANAR thread chaser for M5 threads, model N1-111001-0050, is a compact hand tool designed to restore and clean internal M5 female threads. Intended for maintenance and repair work in metalworking, automotive and machinery applications, this thread chaser removes light corrosion, debris and deformation to recover the correct thread profile and improve fastener engagement. The tool is built for repeated use in workshop environments where accurate thread recovery is required.

Advantages

The FANAR M5 thread chaser provides targeted restoration of internal threads without the need for full re-tapping, reducing time and material removal. Its compact size allows access to confined spaces and threaded holes in assemblies. Constructed from durable tool steel, the chaser offers wear resistance suitable for typical workshop conditions and repeated use. The design focuses on restoring thread form to ensure reliable bolt and screw fit and to prevent cross-threading during assembly.

Suitable for

• Repairing damaged or corroded M5 internal threads in machinery and equipment
• Maintenance work on automotive components that use M5 fasteners
• Workshop and fabrication tasks requiring thread cleaning before assembly
• Restoring threads in metalworking prototypes and small production runs

Key specifications

• Thread size: M5 internal (metric)
• Tool type: thread chaser for internal threads
• Intended use: restoration and cleaning of existing threads
• Construction: tool steel suitable for hand use in maintenance applications
• Form factor: compact, designed for access to confined threaded holes

How to use

Select the FANAR M5 thread chaser for the matching M5 female thread. Secure the workpiece to prevent movement and align the tool squarely with the thread axis. Carefully engage the chaser into the threaded hole and turn by hand in the normal fastening direction to cut away corrosion and debris while preserving the original thread profile. Reverse periodically to clear chips and check fitment with a corresponding M5 fastener. Avoid excessive force; the tool is intended to correct light damage and clean threads rather than re-machine heavily distorted holes.

Usage recommendations

Use appropriate personal protective equipment, apply light cutting fluid for smoother operation when necessary, and inspect threads after chasing to confirm correct engagement with M5 fasteners. Replace the chaser if signs of wear or damage appear to avoid further thread impairment.
