Product Information

Full details

The Mehr 7 Piece Impact Driver Set is an essential tool for professional mechanics and DIY enthusiasts who frequently encounter seized or rusted fasteners. Its primary benefit is the ability to break loose stubborn screws using manual kinetic force, making it indispensable for automotive and workshop repairs. However, users should note that because it is a manual tool, it requires physical force and precision placement to prevent cam-out on fastener heads.

FAQs

Can I use this set with an electric impact gun?

No, this is a manual impact driver designed to be struck by a hammer.

What size drive does the handle accept?

The handle accepts standard 3/8-inch drive accessories.

Are the included bits replaceable?

Yes, the bits are standard size and can be replaced with other 3/8-inch impact-rated bits.

Does this tool work for tightening screws?

Yes, you can reverse the drive direction to use the impact force for seating stubborn screws tightly.

How should I clean the bits?

Use a dry cloth to remove metal shavings and grease. If they become rusty, use a wire brush and a light coating of machine oil.

Troubleshooting

The driver does not rotate when struck.

Check that the internal mechanism is not blocked by debris and ensure you are striking squarely on the center of the driver handle.

The bit keeps slipping (cam-out) during use.

Ensure the bit size matches the fastener perfectly and maintain firm downward pressure against the screw head before striking with the hammer.

Pros and Cons

Pros

  • High torque output without the need for power tools
  • Comprehensive bit selection for slotted and Phillips screws
  • Robust metal storage case included
  • Reliable, manual operation in remote locations

Cons

  • Requires manual effort and hammer strikes
  • Limited bit variety compared to larger specialized sets
  • Potential for user fatigue during extended use

Setup, Compatibility & Care

Setup is straightforward: insert the required bit into the `3/8-inch` adaptor, then attach the assembly to the hand impact driver. Ensure the tool is kept clean of heavy debris to prevent internal mechanism jamming. After use in harsh environments, wipe the bits and the driver with a light machine oil to prevent surface corrosion. Always store the components in the provided metal case to ensure that bits do not go missing and that the internal spring mechanism of the driver remains protected from moisture and grit.
