Seven chrome-moly sockets in clear impact-resistant case

Capri Tools

Capri Tools 5-3390 Universal Impact Socket Set SAE 7 pcs 3/8 in Drive

SKU CH-126E-DBA23

Seven SAE universal impact sockets rotate 360 degrees for angled fastener access in a 3/8 in drive set

  • Product colorTransparent
  • 360-degree rotation reaches tight fasteners easily
  • Chrome Molybdenum steel withstands high-torque impact use
  • Manganese phosphate coating resists corrosion better than black oxide
  • 6-point WaveDrive design prevents fastener rounding
  • Meets ASME B107.110 standards for professional quality

Universal Impact Socket Set 7-piece SAE

The Capri Tools 5-3390 set contains seven SAE universal impact sockets in 3/8, 7/16, 1/2, 9/16, 5/8, 11/16 and 3/4 inch sizes. Each socket features a 3/8 inch drive and rotates 360 degrees for access to angled fasteners. They are forged from Chrome Molybdenum steel with a proprietary heat treatment and manganese phosphate coating. A moulded impact-resistant case keeps the pieces organised.

Mechanics needing angled fastener access

Technicians working in tight engine bays or suspension areas benefit from the universal joint movement. The 6-point WaveDrive profile grips fastener flats to reduce rounding under high torque. Buyers who require metric sizing or a larger drive size such as 1/2 inch must select a different kit. This set covers SAE fasteners only.

360-degree rotation on 3/8 inch drive

The defining specification is the universal joint that allows full 360-degree rotation on a standard 3/8 inch drive. This geometry lets the socket engage fasteners at significant angles where a fixed socket cannot reach. Verify that your impact tool uses a 3/8 inch square drive before purchasing.

Questions about this item

How do I attach the 3/8 in drive universal impact sockets to my impact wrench, and what step is often missed?

Press the socket onto the anvil until the detent pin clicks; the step many miss is verifying the pin is fully seated so the socket cannot spin off under torque.

What maintenance or replacement will the manganese phosphate coating and WaveDrive sockets need over time?

Wipe sockets clean after each use and inspect the coating for wear; replace any socket that shows rounding on the 6-point profile or heavy corrosion the coating cannot stop.

Which limit appears first during sustained high-torque use — heat, wear, or the ASME B 107.110 rating?

The coating and heat-treated Chrome Molybdenum steel handle heat well; the first practical limit is usually fastener or anvil wear before the socket exceeds its ASME B 107.110 rating.
