🔧 Key Features

• Forged Chrome-Vanadium Steel: Precision heat-treated Cr-V steel construction resists high torque, jaw spreading, and rounding under heavy mechanical loads.

• Side-Cutout Wire & Pipe Clearance: Open-side slot design allows sockets to slip over wiring harnesses, sensor pigtails, and rigid metal fluid pipes without damaging delicate connections.

• Comprehensive 10mm–22mm Size Coverage: Versatile 9-piece range tackles oxygen sensors, oil pressure sending units, diesel fuel injection lines, and recessed suspension strut top nuts.

• Precision Non-Slip Profile: Broached internal hex geometries grip fastener flats securely rather than corners, reducing slippage and protecting soft brass or rusty sensor bodies.

• Blow-Molded Storage Case: Heavy-duty organized carry case keeps all 9 specialty sockets organized, protected from moisture, and easy to transport between service bays.

⚠️ Important Safety & Usage Notes

 

1. Hand Ratchet Operation: Use standard hand ratchets or breaker bars; do not use pneumatic or electric impact wrenches on cutout slotted sockets to prevent tool jaw flexing or splitting.

2. Rust Penetrant Application: Apply penetrating oil to rusted oxygen sensors or high-pressure fuel line fittings prior to removal to prevent stripping threads on exhaust manifolds or fuel rails.
