  • 8-point design grips fastener sides to reduce rounding

  • compatible with 3/4-inch drive hand ratchets and torque wrenches
  • manual-use only design prevents damage from power tools

Industrial fastener socket for manual drives

The Steelman 60278-09 is a 3-1/4-inch 8-point locknut socket built for hand-operated 3/4-inch drive ratchets, extensions, adapters or torque wrenches. It targets technicians who service wheel bearing nuts and large industrial bolts without power or impact tools.

8-point geometry reduces corner wear

The eight-point design grips fastener flats rather than corners, lowering the risk of rounding during high-torque break-loose or final-tightening steps. Manual operation only is specified; the socket is not rated for impact or power wrench use.

Black powder coat resists chipping

A durable black powder-coat finish protects the carbon steel body from corrosion and abrasion in shop environments. Laser-etched size markings remain legible over time, and the 3/4-inch drive square fits existing manual drive tools without adapters.

Questions about this item

Will this 3/4-inch drive socket fit my existing breaker bar and torque wrench?

Yes, it works with any hand-operated 3/4-inch drive ratchet, extension, adapter or torque wrench.

How can I confirm the size marking is still legible after heavy use?

The 3-1/4 inch size callout is laser-etched into the steel and will not rub off.

Does the package include a ratchet or extension, or just the socket?

Only the 8-point locknut socket is supplied; ratchets, extensions or adapters must be purchased separately.
