3/4" Drive Deep Impact Socket

The STEELMAN 79398 is a 3/4-inch drive 6-point deep impact socket built for professional mechanics. It is designed for heavy-duty maintenance on large trucks, tractor trailers, farming equipment, and construction machinery. The deep well reaches nuts on extended threads and recessed bolts. Drop forged chromoly steel construction ensures durability under high torque.

Capacity and headroom

The 6-point configuration grips fastener sides rather than corners, reducing rounding and wear during high-torque applications. A ball detent recess secures the socket to ratchets, air wrenches, and extensions. The black phosphate coating resists rust and corrosion in harsh shop environments. Laser etched markings provide permanent size identification.

ASME torque rating

This socket is rated to withstand up to 150% of ASME torque specifications for impact use. It meets the strength demands of oilfield, mass transit, and heavy agricultural service work. Buyers needing smaller drive sizes or standard length sockets should look elsewhere. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

Will the 3/4-inch drive on the 79398 fit my existing ratchet and extensions?

The ball detent recess on the 3/4-inch drive end holds the socket securely onto ratchets, air wrenches, adapters and extensions with a matching 3/4-inch square drive.

How can I verify the 79398 is gripping the fastener correctly during use?

The 6-point shape contacts the flat sides of the fastener rather than the corners, so you will feel solid engagement and see reduced rounding on the nut or bolt head.

Does the 79398 come with any adapters or extensions, or must I buy them separately?

The box contains only the single deep impact socket; any ratchet, air wrench, adapter or extension with a 3/4-inch drive must be purchased separately.
