The kit combines offset and straight socket designs in both 3\/8\" and 1\/2\" drives plus two M12 and M18 thread chasers to clear and realign sensor threads. Constructed from alloy steel with phosphating and heat treatment, the components resist rust and withstand repeated use in garage conditions.\u003c\/p\u003e\n\n\u003ch3\u003eWhich sensor types can I service with this WORKPRO kit?\u003c\/h3\u003e\n\u003cp\u003eThe set covers oxygen (O2) sensors, thermal switches, oil pressure and vacuum sensors.
