BLACKROBOT PB210019M 19 mm Deep Impact Socket, 6-Point, 1/2-Inch Drive

When automotive work calls for a 19 mm socket to reach a recessed fastener, the BLACKROBOT PB210019M deep impact socket pairs a 6-point profile with a 1/2-inch square drive. Its heat-treated chrome vanadium steel construction and black phosphate finish suit use with impact or electric wrenches on vehicle fasteners.

The size and material are marked on the socket, with laser marking designed to remain easy to read, including in low light. That makes it simpler to identify the right tool and put it back in its place between jobs.

Key points

A 6-point design engages the sides of a nut or bolt and is intended to help prevent rounding under the high torque and hammering stress of an impact wrench. The deep profile is useful when a fastener sits farther into a wheel or assembly than a standard socket can comfortably reach. For routine automotive maintenance, that can mean having the right combination of size and reach ready for the job rather than changing to a different socket style partway through.

The socket is made from heat-treated chrome vanadium steel (CR-V). Its black phosphate finish is designed to resist corrosion, rust and wear. Stamped size and material markings provide a durable reference, while the larger laser marking helps make identification more visible when working in dimmer conditions. Customer feedback often highlights effective function and fit for vehicle lug nuts, comments on durability are mixed, with some buyers reporting breakage. These impressions are useful context alongside the socket’s listed construction and intended use.

Fit and sizing

This is a 19 mm socket with a 1/2-inch square drive. Match the socket size to the fastener and the drive to your wrench. Its intended application is automotive fastener maintenance, including work involving vehicle nuts and bolts. A deep socket is the practical choice when access calls for more reach, a shallower socket may suit fasteners that sit close to the surface. The 6-point profile is a useful consideration for high-torque work where secure contact with the fastener matters.

How to use it

Fit the square drive onto a compatible 1/2-inch drive impact or electric wrench, then seat the socket fully on the 19 mm fastener before applying power. Keep the socket aligned with the fastener as you work. The marked size helps with quick selection from a tool drawer, and the material stamp makes it easier to distinguish this CR-V socket from others in a set. It can be used for vehicle maintenance tasks involving the matching fastener size, including lug-nut work where the socket’s deep profile is helpful.

Practical questions

What size fasteners does it fit? It is sized for 19 mm nuts and bolts. Confirm the fastener size before use so the socket seats properly.

What wrench drive does it use? The square drive is 1/2 inch, for use with a matching drive wrench, including impact or electric wrenches.

What do the markings show? The socket has size and CR-V material markings, including laser marking intended to be easy to read in low light.
