INGCO 15-Piece 3/4" Drive Heavy-Duty Industrial Socket Set (Coffret de Douilles 3/4") – Cr-V Steel Construction, 21–50mm Range, Quick-Release Ratchet, and Heavy-Duty Metal Carrying Case (HKTS034151)

Tightening or loosening large-diameter bolts on heavy construction machinery, commercial truck axles, agricultural tractors, or industrial steel structures requires high-torque capacity tools that standard 1/2" drive sets simply cannot handle. Attempting to use under-sized sockets or non-impact-rated drivers on massive fasteners leads to catastrophic tool snapping, fastener rounding, and severe safety risks. The INGCO HKTS034151 15-Piece 3/4" Drive Industrial Socket Set (Coffret de Douilles) is a high-torque mechanical powerhouse engineered for extreme load-bearing strength, precise engagement, and durability in the harshest maintenance environments. Forged from premium Chrome Vanadium (Cr-V) steel, each component is heat-treated and chrome-plated to resist deformation, bending, and oxidation under high-pressure industrial applications.

The mechanical reliability and professional utility of this 15-piece set rely on its robust 3/4" drive quick-release ratchet, comprehensive socket range (21mm–50mm), and heavy-duty reinforced steel carrying case. The large-format sockets feature a 12-point design for secure seating on corroded or oversized hexagonal heads, while the included sliding T-handle and extension bars provide the necessary leverage to break stubborn, rusted connections. Secured in a rugged, partitioned metal box that keeps heavy tools organized and portable, the HKTS034151 equips heavy-duty diesel mechanics, plant engineers, mining maintenance crews, and structural contractors with a professional-grade fastening system.

Key Features

• Industrial 3/4" Drive System – Designed specifically for heavy-duty torque requirements in commercial trucking, agriculture, and large-scale industrial assembly.

• 15-Piece Comprehensive Metric Range – Includes a versatile selection of 10 essential socket sizes (21mm to 50mm) to cover the most common heavy-fastener applications.

• High-Strength Cr-V Steel – Precision-forged Chrome Vanadium steel construction provides maximum torsional rigidity and resistance to impact fracturing.

• Professional Quick-Release Ratchet – Heavy-duty 3/4" drive ratchet head allows for rapid socket changes and efficient operation in tight industrial maintenance spaces.
