Professional Impact Socket

The Capri Tools 5-5221 is a 21 mm 1/2 in drive deep impact socket built for technicians who rely on power tools daily. Its Chrome Molybdenum construction and proprietary heat treatment deliver the strength required in professional garage environments.

6-Point WaveDrive Design

The 6-point WaveDrive geometry grips fastener flats instead of corners, reducing rounding while transmitting high torque from impact guns. This specific profile is the deciding factor when a standard socket would slip or deform under load.

Manganese Phosphate Coating

A military-grade manganese phosphate finish resists corrosion far better than black oxide, maintaining surface integrity through repeated heavy-duty cycles. The deep single-length body sustains engagement on long fasteners without the wear that short sockets exhibit under continuous use.

Highlights

  • Deep 21 mm reach accesses recessed fasteners
  • 6-point WaveDrive design prevents fastener rounding
  • Chrome Molybdenum steel withstands high torque
  • Manganese phosphate coating resists corrosion better than black oxide
  • Proprietary heat treatment ensures lasting durability

Questions about this item

How deep is the 21 mm socket when it is on a 1/2 in drive ratchet?

The single deep length lets the socket reach recessed fasteners that a standard socket cannot engage.

What does the 6-point WaveDrive design do for the 21 mm socket?

It grips the fastener flats more tightly than a traditional 6-point pattern, reducing rounding and giving extra leverage.

What clearance does the 21 mm socket need to fit on a 1/2 in drive tool?

It mounts directly on any 1/2 in square drive; the manganese phosphate coating adds no measurable thickness.
