SKU CH-KT5M-FD13V

A 1/2 inch drive socket with 30 mm depth for automotive fastening tasks

  • Six-point profile grips fastener flats to reduce rounding risk
  • Grey Pneumatic construction delivers professional-grade durability

Grey Pneumatic 81016D Duo-Socket

The Grey Pneumatic 81016D is a duo-socket designed for 3/8-inch drive tools. It combines a 1/2-inch SAE socket with a 30mm metric socket in a single 6-point unit. Mechanics can switch between SAE and metric fasteners without changing sockets.

Suits technicians with mixed fastener sets

Technicians working on vehicles or equipment that use both SAE and metric hardware will find this tool efficient. It reduces the number of individual sockets needed on a rail. Buyers who need only one measurement system or require different drive sizes should look at other options.

30mm metric and 1/2-inch SAE 6-point profile

The defining specification is the dual 6-point profile covering 30mm metric and 1/2-inch SAE sizes on a 3/8-inch drive. This exact combination determines whether the socket matches the fasteners in the specific application. Verify both sizes against the job requirements before purchase.

Questions about this item

What drive size does the 81016D Duo-Socket accept?

The 81016D Duo-Socket is built for a 1/2 inch drive, so it fits directly onto any standard 1/2 inch ratchet or breaker bar without an adapter.

What is the overall depth of the 81016D socket?

The socket measures 30 mm deep, giving enough reach for recessed fasteners while staying compact for tight engine bays.

How do you install the 81016D onto a ratchet, and what mistake should you avoid?

Slide the 1/2 inch square drive onto the ratchet anvil until the ball detent clicks; the common error is not seating it fully, which can cause the socket to pop off under torque.
