KT Pro Tools A6403SP 8 Piece 3/4 Inch Drive SAE Deep Impact Socket Set 6 Point CR-MO Steel 1 to 1-1/2 Inch Heavy Duty Industrial Truck Repair Tools

Unmatched Torque and Reach for Heavy-Duty Industrial and Automotive Applications

The KT Pro Tools A6403SP 8-Piece 3/4" Drive Deep Impact Socket Set is a professional-grade collection engineered for the extreme demands of heavy machinery, commercial truck maintenance, and industrial construction. Forged from high-strength Chrome Molybdenum (CR-MO) Alloy Steel, these sockets are specifically designed to absorb the high-energy impact of 3/4" drive air wrenches without cracking or failing. The specialized deep-well design provides essential access to long bolts and recessed fasteners that standard sockets cannot reach, making this set indispensable for suspension work, engine mounts, and structural assemblies.

Each socket features a precision-machined 6-point configuration that ensures a secure, non-slip grip by making contact with the flat sides of fasteners rather than the corners. This design significantly reduces the risk of rounding off expensive hardware under high-torque conditions. Coated in a rugged phosphate sunk finish for superior corrosion resistance and durability, these sockets meet or exceed stringent ANSI/ASME B107.2 quality standards. Whether you are working in a professional automotive shop or a harsh industrial environment, the A6403SP set delivers the performance and longevity backed by a lifetime limited warranty.

Specifications

Pro-Tip: When using deep impact sockets on 3/4" drive air tools, always ensure the socket is fully seated on the fastener before engaging the trigger. Because deep sockets have more mass and a longer rotational axis than standard sockets, maintaining a perfectly perpendicular angle to the workpiece is critical to prevent vibration and ensure maximum torque transfer.
