INGCO 8-Piece 3/4″ Drive Heavy-Duty Deep Impact Socket Set (90mm Deep Profile, Cr-Mo Cold-Extruded Alloy Steel, Sizes 26mm to 38mm, Heavy-Duty Plastic Carry Case, For High-Torque Impact Wrenches)
Stop shattering standard chrome-vanadium sockets, rounding off expensive hub nuts, and stripping threaded studs under heavy impact loads. The INGCO HKISSD34082L 8-Piece 3/4″ Deep Impact Socket Set completely replaces brittle hand sockets that crack under high-torque power tools. By utilizing cold-extruded Chromium-Molybdenum (Cr-Mo) steel—a specialized metallurgy engineered to absorb extreme kinetic shock without fracturing—this master set gives heavy equipment mechanics, commercial fleet technicians, and structural riggers an indestructible driving system built for extreme industrial service.
Cold-Extruded Cr-Mo Steel Build & Shock-Absorbing Metallurgy
Industrial Chromium-Molybdenum (Cr-Mo) Alloy Steel: Forged from high-grade Cr-Mo steel using cold extrusion processing and precision heat treatment. Cr-Mo offers superior ductility and impact strength compared to standard CR-V steel, allowing the socket walls to flex slightly under high percussive impact hits without shattering or splitting.
Corrosion-Resistant Black Phosphate Coating: Finished with a thick, chemical-resistant black phosphate protective layer that repels water, shop grease, road grime, and harsh automotive solvents to prevent rust and corrosion.
Precision-Machined Drive Pin & O-Ring Slots: Features standard 3/4″ square drive receivers equipped with dedicated safety pin holes and retaining ring grooves to lock the socket securely onto high-torque impact wrench anvils without risk of throwing the socket off mid-job.
90mm Extended Deep Profile & High-Torque Wall Engagement
90mm Extra-Deep Socket Depth: Engineered with an extended 90mm deep profile, providing ample clearance to slide over long exposed wheel studs, protruding axle threads, and recessed structural anchor bolts that short sockets cannot reach.
Off-Corner 6-Point Engagement Geometry: Designed with recessed internal corners that grip the flat sides of hex nuts rather than the delicate corners, dramatically reducing corner rounding and allowing maximum torque transfer on stubborn, rusted, or frozen fasteners.
High-Visibility Stamped Size Markings: Each socket is deeply roll-stamped with clear metric sizing numbers, ensuring rapid size identification even in low-light repair pits or oily shop environments.

Best Use Cases
Commercial Truck, Bus & Heavy Machinery Service: The absolute daily baseline impact socket asset for commercial vehicle mechanics in Salem to service heavy wheel lug nuts, suspension U-bolts, track shoes, and axle hub assemblies.
Agricultural & Earthmoving Equipment Repairs: Perfect for tractor technicians and field service crews to break loose rusted, high-torque bolts on plows, excavators, crushers, and heavy farm implements.
Pencil Carving Art Studio Structural Stand & Machinery Rigging: A valuable studio utility asset for pencil carving artists managing heavy workshop equipment or massive gallery installations. These 3/4″ deep impact sockets provide an unyielding method to assemble heavy steel display frames, adjust massive stone/metal pedestal mounts, and torque down heavy machine lathe bases securely.
Structural Steel Construction & Industrial Plant Maintenance: An indispensable utility carry for riggers and plant maintenance teams to secure structural steel flange bolts, crane rails, and heavy foundation anchor rods.
TK Pro Tip: Cr-Mo impact sockets are an unbeatable high-torque power tool asset, and using the proper retention pin and O-ring setup on your 3/4″ anvil is the absolute secret to safe, uninterrupted job-site operation! Because 3/4″ impact wrenches produce immense percussive shock, never rely solely on a friction ball detent when running high-torque fasteners overhead or in deep service pits. Always slip a steel retention pin through the socket drive hole and lock it with a rubber O-ring around the anvil groove. Additionally, apply a light drop of anti-seize lubricant onto long wheel studs before running sockets down—this prevents galling on the threads and ensures clean, accurate torque delivery every single time!
The TK Tools Promise
