KS TOOLS Metric Thread File, 230mm, 8 Pitches 0.75-3.00mm, Black Oxide 150.1340

A metric thread file that restores damaged external threads on bolts and studs with precision-ground cutting edges. This 230mm tool covers eight common metric pitches from 0.75mm to 3.00mm, making it indispensable for automotive and machinery repair where cross-threaded or burred fasteners must be salvaged quickly.

Advantages

Eight thread pitches in one file eliminate the need for multiple single-pitch tools. The high-grade tool steel body with black oxide finish resists corrosion and maintains sharpness through repeated use. The integrated knurled handle provides a secure grip even with oily hands, while the square cross-section allows access to threads in tight spaces. Each cutting face is ground to exact tolerances, ensuring clean thread restoration without removing excess material.

Suitable for

• Repairing damaged external threads on bolts, studs, and shafts
• Automotive technicians working on engine, suspension, and chassis fasteners
• Machinery maintenance in industrial and agricultural settings
• Restoring metric threads from M3 to M24 diameter range
• General workshop use where thread chasing is required

Recommendations

For best results, clean the damaged thread area before filing and use light pressure with a forward stroke. Match the file's pitch to the thread by visual inspection or thread gauge. After filing, chase with a die if available to ensure full thread form. Store in a dry place to maintain the black oxide finish.
