Extended Product Information

FAQs

What sizes are included in the AK7990 set?

The set includes 4, 4.5, 5, 5.5, 6, 7, 8, 9, 10, 11, 12, 13, and 14mm sockets.

Can I use these sockets with an impact driver?

These are hand-tool sockets. Using them with high-torque impact drivers may damage the steel and voids the warranty.

What material are these sockets made of?

They are manufactured from high-grade, hardened and tempered Chrome Vanadium steel.

Is the socket rail included?

Yes, the set comes supplied on a metal socket rail for organized storage.

Does this set have a warranty?

Yes, the Sealey AK7990 comes with a lifetime guarantee against manufacturing defects.

Troubleshooting

Socket is stuck on the rail

Apply a small amount of penetrating oil to the rail spring and wiggle the socket to release the ball-detent mechanism.

Socket slips on the fastener

Verify that you are using the correct metric size and ensure the fastener head is free of debris or rust buildup.

Pros and Cons

Pros

  • High-grade Chrome Vanadium steel construction
  • Excellent corrosion resistance due to black chrome finish
  • Knurled rings provide superior grip with oily hands
  • Includes convenient rail for storage
  • Backed by a lifetime guarantee

Cons

  • Metric sizes only; lacks imperial/SAE sockets
  • Not intended for use with high-powered impact wrenches
  • Limited to 14mm maximum fastener size
  • Socket rail lacks a locking mechanism for heavy transport

Setup, Compatibility & Care

To begin using the set, simply slide the desired socket off the included rail by applying slight outward pressure. This set is compatible with any standard 1/4" drive ratchet or torque wrench.

To maintain the tool, wipe the sockets down with a clean, dry cloth after every use to remove chemicals and debris. Periodically apply a light coating of machine oil to the surface to preserve the black chrome finish and prevent surface oxidation in humid environments. Avoid using these sockets with pneumatic impact guns, as the high-impact force can lead to structural fatigue.
