GEDORE K 21 80 3/4 Inch Drive 80 mm Hex Socket, UD Profile, Matt Chrome

On a busy factory floor, a maintenance technician reaches for the GEDORE K 21 80 socket to break loose a stubborn 80 mm bolt on a large industrial press. The socket's UD profile grips the flats of the fastener, not the corners, so the bolt head remains intact even after repeated high-torque applications. Hot forged from Gedore Vanadium Steel 31CrV3 and finished in matt chrome, this 3/4-inch drive socket is built to withstand the demands of heavy machinery maintenance.

The matt chrome finish not only protects against rust but also provides a secure grip when handling. Laser-marked size and brand ensure quick identification in a busy workshop.

Ideal use cases

• Industrial machinery maintenance and repair
• Automotive heavy-duty applications, such as truck and bus servicing
• General mechanical work requiring large hex fasteners
• Assembly operations in manufacturing plants
