GIVIMO 7-Piece Metric Thread Chaser Set M10 to M22 Rethreading Tool Kit for Spark Plug O2 Sensor and NOx Sensor Threads with Square Drive and Storage Case

7 Chasers From M10 to M22: Covers spark plug, O2 sensor, NOx and soot sensor threads in one rethreading kit, including a long M14 x 1.25 for deep plug wells

Square Drive for a Ratchet: Each chaser turns with a ratchet so damaged threads are restored smoothly even where a wrench has little swing room

HRC 45-55 Heat-Treated Steel: Hardened carbon steel with a black phosphate finish holds its edge through repeated thread cleaning and resists corrosion

Auto Shop and Home Garage Repairs: Saves stripped spark plug holes on engines in the garage and cleans sensor bungs on exhaust work at the auto shop

Fitted Storage Case: A molded case keeps every thread chaser set piece in its own slot so the right size is easy to find and carry to the next job
