Hex socket, standard series, Fervi BN4E3N009A

What it is

Hex socket, standard series, Fervi BN4E3N009A. Key specifications: connection 1/2", opening (mm) 9, standard DIN 3124.

A socket is a cylinder with a hexagonal or bi-hex profile that fits over the nut and mounts on a ratchet; the category also includes box spanners and T-handle wrenches.

What it is for

Used in mechanical maintenance of machinery and plant, during scheduled shutdowns or breakdowns, for vehicle maintenance, in the workshop and on the road and for tightening nuts and bolts where torque must be accurate and repeatable.

How to use it

Choose a socket of the exact size with the ratchet's drive, standard or deep depending on how far the bolt protrudes. Push it fully onto the nut and pull the handle smoothly, without jerking. Chrome sockets are for hand use only: impact wrenches require impact sockets.
