Overview The INGCO 8-Piece 3/4″ Drive Deep Impact Socket Set (HKISSD34082L) is engineered from industrial-grade Chrome-Molybdenum (Cr-Mo) steel to withstand extreme torque from heavy-duty impact wrenches. Designed with an extended 90mm deep profile, it provides superior reach and secure grip for large mechanical fasteners, structural bolts, and heavy automotive maintenance.
1. Core Engineering Features
Premium Cr-Mo Steel Construction: Forged using cold extrusion and specialized heat treatment processes to maximize durability, impact resistance, and shatter prevention under intense percussive loads.
3/4″ Drive & 90mm Deep Profile: Features a heavy-duty 3/4-inch square drive anvil interface and an extended 90mm length to easily access recessed bolts, wheel hubs, and long protruding threaded rods.
8-Piece Large Metric Matrix: Covers a comprehensive range of heavy-duty metric sizes perfectly suited for commercial truck and industrial machinery applications.
High-Torque Compatibility: Specifically optimized to pair safely with high-torque 3/4″ cordless and pneumatic impact wrenches (including INGCO models CIWLI201351, CIWLI20135, and UCIWLI20135).
2. What’s Included in the Box
8 x 3/4″ Drive Deep Impact Sockets (Sizes: 26mm, 27mm, 29mm, 30mm, 32mm, 35mm, 36mm, 38mm)
1 x Heavy-Duty Plastic Storage Box
3. Primary Use Cases
Commercial truck, tractor, and heavy fleet wheel lug nut removal
Structural steel erection, bridge building, and large flanged pipe bolting
Agricultural equipment, excavator, and industrial plant machinery maintenance
4. TK Tools Pro-Tip
Always use Chrome-Molybdenum (Cr-Mo) sockets like these on high-torque impact wrenches rather than standard Chrome-Vanadium (Cr-V) hand-tool sockets. Cr-Mo is engineered to absorb extreme percussive strikes without shattering. For maximum power transfer and to prevent rounding off fasteners, ensure the 90mm deep socket is fully seated over the bolt head before engaging the impact trigger!
