Application & User

The Ampco DWI-3/4D1-1/8 is a 3/4 inch drive deep impact socket built for heavy-duty fastening work. It suits mechanics and industrial technicians who need non-sparking tools in hazardous environments.

Critical Specification

The socket measures 1 1/8 inches across a six-point opening and is machined from nickel aluminium bronze. This alloy meets ASTM A342 and carries FM approval for use where spark ignition must be avoided.

Sustained Load Behaviour

The bronze construction resists deformation under repeated high-torque impacts better than standard steel sockets. Its unfinished surface maintains grip on fastener flats during extended use without rounding off corners.

Questions about this item

What does the 1 1/8 in socket size mean when I put it on a fastener?

It fits a 1 1/8 in SAE hex nut or bolt head with a 6-point grip that spreads torque across the flats to reduce rounding.

What does the 3/4 in drive standard cap in practice?

The 3/4 in square drive matches heavy-duty impact guns and ratchets, so the tool transmits high torque without the drive end slipping or shearing.

How deep is the socket and what clearance does it need?

The deep well lets the socket reach over long threads or recessed fasteners, while the 6-point nickel aluminium bronze body fits standard 3/4 in drive accessories.
