Each socket is slotted to clear sensor wiring, finished from chrome-molybdenum steel for strength, and sized to fit 22mm (7\/8\"), 27mm, and 29mm hex fittings used across a wide range of cars and light trucks. The set mixes 1\/2\" and 3\/8\" drive pieces, including deep and offset styles for stubborn or recessed fittings.\u003c\/p\u003e\n\n\u003ch3\u003eWhich sizes are included and what does each socket do?\u003c\/h3\u003e\n\u003cp\u003eThe seven sockets cover the typical O2 sensor hex sizes plus oil pressure senders and vacuum\/pressure switches. You get both long and short slotted 22mm oxygen sensor sockets and larger 27mm and 29mm sockets for pressure senders on older GM models and other vehicles.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e1 × 1\/2\" drive × 27mm (12-point) oil pressure sending unit socket\u003c\/li\u003e\n  \u003cli\u003e1 × 1\/2\" drive × 29mm (6-point) pressure\/vacuum switch socket with slot\u003c\/li\u003e\n  \u003cli\u003e1 × 1\/2\" drive × 7\/8\" (22mm) long slotted O2 sensor socket\u003c\/li\u003e\n  \u003cli\u003e2 × 3\/8\" drive × 7\/8\" (22mm) slotted vacuum switch sockets\u003c\/li\u003e\n  \u003cli\u003e1 × 3\/8\" drive deep 1-1\/16\" \u0026amp; 1\" (27mm) oil pressure socket for deep switches\u003c\/li\u003e\n  \u003cli\u003e1 × 3\/8\" drive × 7\/8\" (22mm) short slotted O2 sensor socket\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do slotted sockets make O2 sensor jobs easier?\u003c\/h3\u003e\n\u003cp\u003eSlotted sockets free the sensor wiring so you can turn the hex without disconnecting or cutting the harness, saving time and preventing wiring damage.
