Ampco I-1/2D3/4 Impact Socket 3/4 in 1/2 in Drive

SKU CH-1A57-S7DRH

A non-sparking 3/4 inch impact socket with a 1/2 inch drive, made from nickel aluminum bronze to ASTM A342 and FM Approved

  • ASTM A342 compliance ensures reliable strength for critical fastening
  • FM Approved rating confirms safety for hazardous-environment use
  • Nickel-aluminium bronze construction resists sparking and corrosion in volatile areas
  • 6-point hex profile grips flats securely to prevent rounding
  • 1/2-inch drive impact rating handles high-torque applications without failure

Impact Socket for Safety-Critical Work

This Ampco impact socket is a 3/4 inch SAE tool with a 1/2 inch drive. It is made from nickel aluminium bronze, a non-sparking and non-magnetic alloy suited for hazardous environments. The six-point hex design grips fastener flats to reduce rounding. It meets ASTM A342 and FM approval standards.

Upgrade from Standard Steel Sockets

The jump is worth it when working near flammable vapours, dust or explosive atmospheres where a steel tool could create an ignition source. It replaces standard chrome or impact-grade steel sockets in oil and gas, chemical, mining and marine maintenance. The unfinished surface avoids plating that can chip and contaminate sensitive processes.

3/4 Inch Capacity with Industrial Headroom

The 3/4 inch hex opening handles common heavy-equipment fasteners in the listed size. The bronze alloy provides corrosion resistance and durability under repeated impact loading. It runs out when the application requires a different drive size, a larger or smaller hex opening, or a spark-resistant tool certified to a standard not referenced here.

Questions about this item

Does the 1/2 in drive square fit my impact wrench anvil?

The socket has a 1/2 in square drive that matches standard impact wrench anvils of the same size.

How do I seat the socket so it does not slip off the fastener?

Align the 6-point hex opening over the 3/4 in fastener, press firmly until the detent ball engages, then apply torque.

Will the nickel aluminium bronze alloy need lubrication or replacement after heavy use?

The unfinished bronze resists corrosion and sparking; inspect for wear or cracking and replace if the hex profile rounds out.
