Westward 3/8 in Drive Impact Socket Bit

This 3/8 inch drive impact socket bit is built for mechanics and technicians who need a reliable metric hex bit for fastening tasks. The 4 mm tip size suits common automotive and industrial hardware. Alloy steel construction provides the strength required for high-torque impact applications. It is a focused tool for professional and serious DIY use.

Alloy Steel Build and Black Oxide Finish

The bit is forged from alloy steel and finished with black oxide to resist corrosion during daily shop use. Its 2 23/64 inch overall length fits standard 3/8 inch drive impact wrenches and allows access to recessed fasteners. The replaceable insert design is not featured, so the bit is a single durable piece. Impact rating confirms suitability for powered driving.

Metric Hex Tip for Direct Engagement

The 4 mm hex tip engages metric socket head cap screws and set screws directly without a separate socket. This reduces the stack height and potential wobble compared to socket-and-bit combinations. The fixed tip means no insert changes are needed, simplifying workflow on repetitive jobs. The tool is supplied ready for immediate use in impact-rated conditions.
