Why this one

3/4 to 1/2 inch reducer

Reduces a 3/4 inch drive ratchet or handle to 1/2 inch drive, so the bigger handle and its leverage can work on 1/2 inch drive sockets.

Ball detent

A ball detent on the male end securely grips the socket, so it stays on the adapter while you work.

Satin finish

A satin finish gives a better grip when you are handling sockets and fitting the adapter.

Socket clip, adapter set

Supplied with a metal socket clip for use with a socket rail, and it is also included in adapter set TTADP17.

Read the full description

The Teng Tools M340086-C is a reducing adaptor with a 3/4 inch female square drive and a 1/2 inch male square drive. It allows a 3/4 inch drive ratchet or handle to be used with smaller 1/2 inch drive sockets, so mechanics can switch between drive sizes without changing their primary ratchet. Buyers often search for it as a 3/4 to 1/2 adapter or a 3/4 to 1/2 drive adapter; the direction runs from the larger drive down to the smaller one.

A ball detent on the male end firmly grips the 1/2 inch socket. The adaptor is chrome vanadium (CrV) with a satin finish for secure handling, and it is supplied with a metal socket clip for use with a socket rail.

The length is 40 mm (1.6 in) and the weight is 164 g (5.8 oz). Teng Tools rates it Impact: No, so it belongs with hand ratchets, extension bars and handles rather than an impact wrench.

What you get: 1 x reducing adaptor, 3/4 inch female to 1/2 inch male, with a metal socket clip. Ratchet, extension bar, sockets and socket rail are not included.

  • The female end fits a 3/4 inch drive ratchet, extension bar or handle and the male end takes 1/2 inch drive sockets. As a 3/4 female to 1/2 male adapter it lets you switch between drive sizes without changing your primary ratchet, so the 3/4 inch drive handle you already have on the job also covers the smaller sockets.
  • A ball detent on the 1/2 inch male end grips the socket firmly, so it stays on the adapter while you line it up on the nut and while you pull the tool back out. A firm pull releases it when you change size. A ratchet adapter goes on and off many times in a working day, so a secure hold on the socket matters.
  • Made from chrome vanadium (CrV) with a satin finish for secure handling and a better grip when handling sockets. The body is marked CR-V. A socket reducer is a small part that is easy to lose in a large drawer, so it is supplied with a metal socket clip for use with a socket rail, where it can stay with the rest of the set.
  • Length is 40 mm (1.6 in) and the weight is 164 g (5.8 oz). The short body keeps the socket close to the drive and adds little reach, which helps where there is limited room around a large fastener. Store this square drive adapter on the rail at the end of your 1/2 inch drive sockets so it is always there when you need it.
  • Teng Tools rates it Impact: No, so it is for hand ratchets, extension bars and handles, not for an impact wrench. Use it when a 3/4 inch drive tool is already in your hand and the fastener calls for a 1/2 inch drive socket, whether in a service bay, a workshop or out on a job. Ratchet and sockets are not included.
