Model 800 Hex Bits - 4 mm Round Shank
Match small hex fasteners with a bit made for an 800-style electric screwdriver. These magnetic tips use a 4 mm round shank rather than a standard quarter-inch drive.
✅ Fit the small hex size accurately - H1.5 to H4 selections let you choose the tip around the actual fastener.
✅ Keep a matching bit on the driver - Magnetic construction provides retention behaviour for the supported screwdriver arrangement.
✅ Choose access length for the task - 40 and 60 mm options provide different reach within the matching tool format.
Check the Shank as Well as the Tip
Select the 4 mm round shank only for a driver that accepts that fitting. The hex designation refers to the screw-driving tip, so it should not be confused with a quarter-inch hex shank.
Single-bit and five-piece set selections are available in S2 steel. Choose both the length and tip size, and use the torque settings suitable for the fastener and driver.
