Insulated Wiha extensions, T-handles and tool shanks for socket wrenches
Wiha extensions, T-handles and tool shanks extend a socket set, so you reach bolts that sit deep or behind other parts, or drive a socket with a different tool. Many of them are insulated for work on electrical installations.
First pick the square drive of your ratchet and sockets: the insulated extensions come in 1/4", 3/8" and 1/2", in lengths from 75 to 250 mm. A short extension keeps the ratchet close to the work, a long one reaches into a deep housing. An insulated transverse handle for 3/8" sockets gives a two-handed grip when you need to turn many revolutions quickly.
For interchangeable tools there are tool shanks and power connectors with a ball, going from a 1/4" hexagon socket to a square of 1/4", 3/8" or 1/2". That way you drive a socket with a screwdriver handle or a machine. The System 6 interchangeable shaft turns a screwdriver into a socket wrench. Complete sets with a ratchet are among the Wiha ratchet and socket sets 1/4", 3/8" and 1/2", and the whole family sits under Wiha sockets and ratchets.
