  • 3/8-inch drive fits standard ratchets and extensions

  • Duo-Socket design combines two functions in one tool
  • 6-point geometry grips flats to reduce rounding

3/8 Drive Deep Duo-Socket

This 3/8 drive deep duo-socket features a 7/8 inch size and 6-point design for secure fastener engagement. It is built for mechanics and technicians who need reliable socket performance. The tool suits automotive repair, maintenance tasks, and general garage work. Grey Pneumatic supplies this item new and ships it directly from the manufacturer.

Suits single-socket needs; not for multi-size sets

This socket fits users who require one specific 7/8 inch deep 6-point tool for targeted jobs. It works well for professionals and DIYers tackling individual fastener sizes. Buyers needing a full range of socket sizes or a comprehensive socket set should look at multi-piece kits instead. Orders of $75 or more ship free from the supplier.

Verify drive size and fastener fit

Check that your ratchet or driver uses a 3/8 inch drive to match this socket. Confirm the fastener you are working on requires a 7/8 inch 6-point deep socket for proper clearance and grip. Ensure the deep length suits the recessed bolts or studs in your application. The product ships directly from the manufacturer.

Questions about this item

What drive size ratchet or breaker bar is required to turn the 3/8 drive end of this socket?

A 3/8 inch drive ratchet, breaker bar or impact gun fits the 3/8 drive square on the Grey Pneumatic 81028D.

Can the 7/8 inch hex end engage fasteners on older SAE equipment alongside metric tools?

Yes, the 7/8 inch 6-point hex opening works on SAE fasteners commonly found on older machinery while metric sockets cover other sizes.

How can I confirm the 6-point geometry is gripping the fastener flats instead of rounding corners?

After seating the socket fully, apply steady torque; the 6-point design contacts the flat sides of the nut or bolt, reducing corner rounding.
