Ampco 3/4" Drive Impact Socket

The Ampco I-3/4D1-1/8 is a 1-1/8 inch SAE impact socket built for 3/4 inch drive tools. Its six-point nickel aluminum bronze construction meets ASTM A342 and FM Approved standards. This non-sparking socket suits maintenance crews in hazardous environments where ferrous tools create ignition risk. Buyers needing standard chrome-vanadium sockets for general garage work should look elsewhere.

Sustained Impact Performance

Nickel aluminum bronze resists deformation under repeated high-torque impacts better than many ferrous alloys. The six-point profile distributes load across fastener flats to reduce rounding during extended use. Unfinished surfaces maintain consistent grip without plating that can chip under heavy vibration. This socket is not designed for continuous high-speed power tool operation beyond rated impact limits.

Compatibility Check

Verify your impact wrench or driver has a 3/4 inch square drive anvil to match this socket. Confirm the fastener requires a 1-1/8 inch SAE six-point socket before ordering. Ensure your application permits non-sparking tools rated to ASTM A342 and FM Approved standards. This socket will not fit 1/2 inch or 1 inch drive tools.

Questions about this item

Does the 3/4" drive impact socket run hot or draw continuous power during all-day use?

No — it is a passive hand tool with no motor or electronics, so it generates no heat and consumes no power.

What drive tool must I already own to turn this 3/4" drive, 1-1/8" SAE socket?

A 3/4" square-drive impact wrench or breaker bar is required to engage the socket's drive end.

Will this ASTM A342-rated, FM-approved socket damage older 3/4" drive anvils or fasteners?

The nickel-aluminum-bronze construction is non-sparking and non-marring, so it protects both legacy anvils and softer fastener heads.
