What it is
Long socket with hexagon bit Fervi BN413L005A is a socket wrench with a 1/2" drive fitted with a long hexagon bit, ideal for reaching socket-head screws and bolts or those in hard-to-access positions. The long configuration ensures grip and torque even when the working depth is great.
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 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.
