Ampco DWI-1/2D27MM 1/2 in Drive Impact Socket 27 mm Hex Deep

SKU CH-0DY6-A8T7R

A non-sparking 1/2 in drive deep impact socket in 27 mm hex for hazardous environments, meeting ASTM A342 and FM approval

  • 27 mm deep socket reaches recessed fasteners in tight engine bays
  • Nickel aluminium bronze construction resists sparking in hazardous environments
  • 1/2 inch drive fits standard impact wrenches for high-torque applications
  • Six-point hex profile grips flats to prevent rounding under load
  • FM approved and meets ASTM A342 for certified safety compliance

Socket Specification

This 27 mm hex deep impact socket fits a 1/2 inch drive and is built to ASTM A342 and FM Approved standards. It suits mechanics who need a non-sparking tool for hazardous environments. The 6-point opening grips fastener flats to reduce rounding under high torque.

Practical Limits

The socket is rated for impact use only when paired with a compatible 1/2 inch drive impact wrench. Its nickel aluminium bronze construction prevents sparking but offers lower hardness than steel, so it is not suited for general-purpose heavy-duty steel fastener work. The deep profile reaches recessed nuts but adds length that may limit access in tight cavities.

Build And Mounting

The unfinished nickel aluminium bronze surface resists corrosion without plating that could chip. The 1/2 inch square drive engages standard impact extensions and adapters securely. The 6-point hex geometry distributes load evenly across the fastener, reducing wear on both the socket and the bolt head during repeated impact cycles.

Questions about this item

Should I choose a 27 mm deep impact socket or a different size for my application?

Select the 27 mm size only when the fastener you are turning measures 27 mm across the flats; the deep well reaches recessed bolts that a standard socket cannot.

What does the ASTM A342 reference mean once the socket is in use?

ASTM A342 confirms the nickel-aluminium-bronze alloy meets the specified magnetic-permeability and mechanical requirements for non-sparking, non-magnetic tools.

How does the 1/2 in drive standard limit the torque I can apply?

The 1/2 in square drive is rated for typical impact-wrench output; exceeding the drive's shear capacity will damage the socket before the fastener yields.
