Impact Socket 3/4" 75 mm 12-Point Cr-Mo for Impact Wrench 1.74 kg, JCB Tools

Key Facts — JCB Tools Impact Socket 3/4" 75 mm

• Brand: JCB Tools
• Model: JCB65628
• EAN: 5905101399570
• Type: Impact socket, 12-point
• Size: 75 mm
• Square drive: 3/4"
• Material: Chrome-molybdenum steel (Cr-Mo)

The JCB Tools 75 mm impact socket is made for impact wrenches with a 3/4" square drive and for fasteners of the size found on truck hubs, construction plant, agricultural machinery and heavy industrial joints. The socket weighs 1.74 kg, giving it the mass needed to absorb blows from a powerful impact wrench without deforming.

The socket is made from chrome-molybdenum steel, a material tougher than chrome-vanadium and therefore able to take repeated impacts, shocks and high torque without cracking. That is exactly why it is the standard material for impact sockets.

The 12-point profile lets the socket go onto the nut at more angles than a 6-point, making work easier where the impact wrench cannot be positioned freely. The 3/4" square drive fits impact wrenches, ratchets and torque wrenches with the same drive.

Why workshops choose a Cr-Mo impact socket for heavy fasteners

Because a standard socket is not built for impacts. Chrome-vanadium sockets are hard but brittle and can crack when an impact wrench delivers thousands of blows a minute at hundreds of newton-metres. The Cr-Mo steel in the JCB Tools impact socket is tougher and absorbs that energy, making it both safer and longer-lasting on heavy fasteners seized by rust and time.

Applications for the impact socket

The impact socket is used for removing and fitting hub nuts on trucks, buses and trailers, servicing construction and agricultural machinery, industrial maintenance of heavy bolted joints, and steel structure assembly. It belongs in truck workshops, machine shops and heavy vehicle service units.

Technical Specifications

Used by: Truck mechanics, machine repairers, agricultural mechanics, heavy vehicle tyre fitters and industrial maintenance technicians.

Common in: Truck and bus workshops, construction plant, agriculture, industrial maintenance and steel construction.

Frequently Asked Questions (FAQ)

Does the JCB Tools 75 mm impact socket fit hex nuts?

Yes. A 12-point socket grips both 6-point and 12-point fasteners at 75 mm across flats, and can go on at twice as many angles as a 6-point socket. On heavily torqued or rusted hex nuts, however, a 6-point socket has more contact area against the flats, reducing the risk of rounding the corners at very high torque.

Which impact wrench does the JCB Tools 3/4" 75 mm impact socket fit?

Impact wrenches with a 3/4" square drive, whether pneumatic, cordless or corded. The socket also fits ratchets, breaker bars and torque wrenches with 3/4" drive. Do not use a 1/2" adaptor to drive a 75 mm socket — the torque on fasteners of that size exceeds what a 1/2" drive is rated for, and the adaptor becomes the weak link.

What separates the JCB Tools Cr-Mo impact socket from a standard chrome-vanadium socket?

Toughness. A standard chrome-vanadium socket is hard and polished but brittle, and can crack or shatter under the blows of an impact wrench. The chrome-molybdenum steel in the JCB Tools impact socket is tougher and absorbs impact energy without cracking. That is why impact sockets should always be used with impact wrenches, and standard sockets only with hand tools.
