Hexagon head bit 1.5 mm across flats for miniature screws, 44 mm long - Delvo DLB2321

A 1.5 mm hexagon forgives no crooked start. This bit is the smallest size of the NK4DX range and guides the screw head across the full flat, so the torque of the electric screwdriver arrives cleanly even on the smallest parts.

Benefits

• The smallest size of the range. Together with 2, 2.5, 3 and 4 mm, NK4DX covers the band where hand wrenches become too coarse.
• Production at Nitto Kohki from raw material to finished bit keeps the runout of the bit axis low, which matters more at 1.5 mm than at any larger size.
• Special alloy with controlled heat treatment and close hardness testing, prepared for screwdriver bits alone.
• Half round 4 mm shank, seated directly in the H4 holder of the Delvo screwdrivers, with no chain of adapters between clutch and screw.
• Overall length of 44 mm, short enough for a stiff tool and long enough to reach into a counterbore.

Applications

Optics and sensor assembly, connectors and small appliances, precision engineering and laboratory construction. The bit is at home wherever 1.5 mm hexagon heads are tightened to a defined torque instead of by feel.

Matching accessories

The ESD electric screwdrivers DLV-7410-BME6, DLV-7420A BME6 and DLV-7331-BME6 take the bit directly, on a 1/4 inch holder it works through the ADA-HR4-D63 adapter. Because screws of this size are easily lost while being placed, the ring magnets MAG-RING-4,7 and MAG-RING-6,0 are worth having. The next size up in the range is DLB 2322 with 2.0 mm.
