The VECTOR VINA D4*65 Ø4mm wing-type round shank hex nut setter is a specialized accessory designed for 800-type round shank electric screwdrivers (4mm shank diameter). This product is commonly referred to as a round shank nut driver bit, Ø4mm hex socket bit, or external hex nut setter for electric screwdrivers.
Manufactured from durable chrome-vanadium steel / S2 steel for long service life, the body is laser-engraved with the VECTOR VINA S2 marking. Its non-magnetic socket design makes it ideal for assembling electronic components, PCBs, or magnetic-sensitive equipment. The 4mm round shank features locking wings for secure engagement in the chuck of 800-series electric screwdrivers.
The D4*65 socket series has an overall length of 65mm and covers a wide range of internal hex sizes from 3mm to 10mm. To select the right model code, measure the distance across flats of the external hex bolt head or nut to be driven: corresponding codes range from D4*65*AF3 (3mm hex size, 6mm socket outer diameter) to D4*65*AF10 (10mm hex size).
