Capri Tools 3/8 in Drive 16 mm Universal Impact Socket

SKU CH-921T-4XRR2

A 3/8 in drive 16 mm universal impact socket rotates 360 degrees for fastener access, uses Chrome Molybdenum steel with manganese phosphate coating, and meets ASME B 107.110 standards

  • 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 professional quality standards

3/8" Drive 16 mm Universal Impact Socket

This 3/8 inch drive 16 mm universal impact socket fits standard impact wrenches and ratchets. The universal joint rotates 360 degrees for access to fasteners at difficult angles. It is built from premium chrome molybdenum steel with a proprietary heat treatment for high-torque durability. The manganese phosphate coating provides military-grade corrosion resistance.

Thermals noise and power draw

As a hand tool this socket produces no heat, noise or electrical draw during use. The manganese phosphate finish resists corrosion better than black oxide coatings under normal workshop conditions. The 6-point WaveDrive design distributes torque evenly across fastener flats to prevent rounding. It meets and exceeds ASME B 107.110 performance standards for impact sockets.

16 mm 6-point WaveDrive fit

The 6-point WaveDrive geometry grips 16 mm fastener flats more tightly than traditional profiles to reduce rounding risk. This socket is not for fasteners of other sizes or for applications requiring a fixed non-universal joint. Buyers needing different drive sizes or hex dimensions must select another socket. California Proposition 65 warnings apply for chemical exposure.

Questions about this item

How do I install the 3/8 in Drive 16 mm Universal Impact Socket and what step do people often miss?

Attach the socket to a 3/8 inch drive impact wrench, align the 16 mm opening with the fastener, and engage the 360 degree universal joint for angled access; the step often missed is ensuring the joint is fully seated before applying torque to avoid slippage.

What maintenance or replacement will the 3/8 in Drive 16 mm Universal Impact Socket need later?

Inspect the manganese phosphate coating for wear and the 6-point WaveDrive profile for rounding after heavy use; replace the socket if the universal joint develops excessive play or the coating is compromised, as corrosion resistance will decrease.

What limit appears first on the 3/8 in Drive 16 mm Universal Impact Socket under sustained high-torque use?

The universal joint's range of motion and the Chrome Molybdenum steel's heat-treated hardness define the practical limit; sustained maximum torque from power tools will stress the joint mechanism before the 6-point WaveDrive design yields.
