Hex socket bit 5.5 mm across flats, largest size of the range, 8 mm socket - Delvo DLB2426

The larger the hexagon, the higher the moment running through the socket. At 5.5 mm across flats this is the largest size in the NK4DB range, meant for bolts and nuts that still stay within a short 44 mm tool path on an electric screwdriver.

Benefits

• 5.5 mm across flats, the largest size of the range. Four sizes from 4.0 to 5.5 mm cover the whole band with a single type of screwdriver.
• Socket body of 8 mm diameter, paired with exactly this size by the manufacturer. The wall thickness carries the higher moment of the larger heads.
• Hardness grade F for bolts and nuts rather than the hard grade of the Phillips bits, so the socket stays tough under shock load.
• Positive H4 drive through the 4 mm half-round shank, without an adapter, clockwise and counter-clockwise alike.
• Made at Nitto Kohki from raw material to finished bit, with close hardness testing and low runout of the bit axis.

Applications

Frame and profile joints, motor and gearbox brackets, sheet metal housings and earthing connections in equipment building. The right pick whenever the hexagon is too large for the smaller sizes of the range while a hand tool would be unnecessary. The bit is carried by the DLV7400A, DLV5700, DLV5800, DLV7300 in BME design, DLV7000, DLV8000 and DLV3300 series.
