8-Piece 3/4-Inch Metric Impact Socket Set

The STEELMAN 79273 set provides eight 6-point metric sockets ranging from 26mm to 38mm on a 3/4-inch drive. It is built for technicians servicing heavy-duty trucks, tractors, construction machinery and mass-transit fleets where large fasteners are standard. Drop-forged chromoly steel with heat treatment delivers the strength required for high-torque impact work. The black phosphate finish resists rust and corrosion in harsh shop environments.

Ball Detent Recess and 6-Point Geometry

Each socket includes a ball detent recess on the drive end that locks securely onto ratchets, air wrenches, adapters and extensions during heavy vibration. The 6-point profile contacts fastener flats instead of corners, reducing rounding and wear under extreme loads. Chromoly construction absorbs repeated hammer blows without cracking or deforming. No moving parts or lubrication points mean silent operation and zero power draw.

California Proposition 65 Compliance Notice

The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. This disclosure satisfies regulatory requirements but does not alter the mechanical function of the sockets. No software, storage cases or additional accessories are included in the package. Buyers needing imperial sizes, smaller drive formats or organised storage must source those separately.

Questions about this item

How do I install the 3/4-inch drive sockets onto my impact wrench, and what step is often missed?

Align the ball detent recess on the 3/4-inch drive end with the wrench anvil and press firmly until the ball seats; the step often missed is verifying the detent has fully engaged before applying torque.

What maintenance will the black phosphate finish on the 26mm through 38mm sockets need over time?

Wipe the sockets clean after each use and apply a light coat of oil to the black phosphate surface to maintain rust and corrosion resistance, especially in humid or salt-air environments.

Which limit appears first when using the 6-point chromoly steel sockets continuously on heavy-duty fasteners?

The 6-point design grips fastener flats rather than corners, so the practical limit under sustained use is fastener rounding or socket wear before the chromoly steel itself yields.
