GIVIMO 7-Piece Metric Thread Chaser Set Thread Restorer Tool Kit M10 M12 M14 M18 M20 M22 Rethreading Kit with Storage Case for Spark Plug and Oxygen Sensor Thread Repair

Carbon Steel Build: Heat-treated carbon steel chasers hardened to HRC 45 to 55 with black phosphate finish; chasers hold thread form through repeat engine passes.

7 Metric Sizes: Set covers M10x1.0 M14x1.25 combo, M12x1.25, M14x1.25 standard and long, M18x1.5, M20x1.5, M22x1.5 for spark plug O2 NOx and soot sensor work.

Square Drive Fit: Each chaser takes a square drive socket so 3/8 or 1/2 in ratchets turn the tool; works in tight engine bays where a T-handle does not swing.

Spark Plug and O2: M10/M14 combo chases spark plug threads on most passenger cars; M12x1.25 and M18x1.5 chase the two common O2 sensor seats for quick repair work.

Labeled Case: Blow-molded storage case holds each chaser in a labeled slot for fast pick; kit moves from a home garage bench to a mobile mechanic van without loss.
