FAQs

What type of screws are these bits designed for?

These bits are specifically designed for T40 Torx screws.

Are these bits suitable for heavy-duty applications?

Yes, these bits are impact rated and designed to withstand the high forces of impact drivers, making them suitable for heavy-duty applications.

How long will the bits last?

The lifespan of the bits depends on usage and care. The FlexTorq design and durable steel construction are intended to provide extended life compared to standard bits.

Can I use these bits with a regular drill?

Yes, you can use these bits with a regular drill, but they are optimized for impact drivers.

What is the benefit of the FlexTorq design?

The FlexTorq design allows the bit to flex with the torque of the impact driver, maximizing bit life and turning force.

How do I choose the correct bit for my screw?

Ensure you use the correct Torx size (T40 in this case) for your specific screw.

Troubleshooting

Bit slips or strips the screw head.

Reduce the torque setting on your impact driver. Ensure the bit is fully engaged in the screw head.

Bit breaks during use.

Check that you are using the correct bit size and applying the appropriate pressure. Consider using a slower speed setting.

Bit seems loose in the impact driver.

Ensure the bit is fully inserted and locked into the chuck. Check the chuck for wear.
