What it is

Spark plug socket, Fervi BN4C4L021A. Key specifications: size (mm) 21, connection 3/8", length (mm) 65.

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 and for vehicle maintenance, in the workshop and on the road.

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.
