Maximize Your Torque and Precision with Professional Grade Impact Hex Bits

The KT Pro Tools A3401MP 6-Piece 3/8" Drive Impact Hex Bit Socket Set is an essential upgrade for automotive technicians and industrial maintenance professionals who demand reliability under high-torque conditions. Engineered specifically for use with impact wrenches, these hex bit sockets are designed to withstand the rigors of heavy-duty applications that would shatter standard chrome sockets. Each socket features high-visibility standard markings etched into the side, allowing for rapid identification in fast-paced shop environments and ensuring you always grab the right tool for the job.

This comprehensive metric set provides the most commonly used sizes ranging from 4mm to 12mm, making it perfect for working on modern European and Asian vehicle braking systems, engine components, and machinery assemblies. The 6-point design ensures a secure, non-slip grip on fasteners, reducing the risk of rounding off expensive hardware during removal or installation. Whether you are performing routine maintenance or tackling a complex engine teardown, the A3401MP set delivers the efficiency and durability required to make your next project smoother and more professional.

Key Features

  • High-Impact Durability: Designed for use with 3/8" drive impact tools to handle extreme torque.
  • Easy Identification: Each socket features clear, standard markings on the side for quick size selection.
  • 6-Point Precision: Ensures maximum contact with hex fasteners to prevent slippage and hardware damage.
  • Professional Efficiency: Streamlines your workflow by providing a reliable fit for the most common metric hex sizes.
  • Industrial Versatility: Ideal for automotive, construction, and mechanical maintenance tasks.

What's Included

(6) 3/8" Drive Impact Hex Bit Sockets in the following Metric sizes:
4mm, 5mm, 6mm, 8mm, 10mm, and 12mm.

Pro-Tip: When using impact hex bits, always ensure the bit is fully seated into the fastener head before engaging the impact wrench. This prevents unnecessary vibration and "cam-out," ensuring the maximum life of both your bit and the fastener. For stubborn or rusted bolts, a quick spray of penetrating oil used in conjunction with these impact bits will yield the best results.

Would not work in my jeep
Color: Textured
This seems like a decent holder, however it is not universal as it would not fit in my jeep. Check to make sure you have the right kind of air vents for it. I could not get it to work for my vehicle as the vents are too wide.

Works great!
Color: Black, Color: Black
This is a very simple, lightweight phone mount. It works well, I’m surprised how securely it fits on the car vent. I’ve tried others and couldn’t get them to fit right. My phone slides into the top and fits nicely. It was easy to install.

No drilling required
Size: Large
I installed this on my 2021 4Runner with the adhesive provided and no drilling. It has been a few months and it’s still solid. I live in Hawaii and the temps in the car have reached over 100* F pretty consistently and the adhesive has held up very well. There are a lot of attachment points for whatever you want to use it for. I only wish they sold the magnetic mount that it comes with so everything can match up. I use it for my phone and baby monitor. I would purchase this again.
