Why this one

Bends to reach

A flexible extension bends along its length, so the socket can reach a screw or small bolt tucked behind a bracket, hose or panel.

150 mm, 1/4-inch drive

A 150 mm (5.9 inch) bar that fits between a 1/4-inch drive ratchet, spinner or handle and the socket.

For light running down

Use it for light running down and removal of small fasteners in engine bays, electronics enclosures and machinery.

Tight access, awkward angles

Where a rigid extension needs a straight line to the fastener, this one works at an angle.

Read the full description

The Teng Tools M140038-C is a 1/4 inch drive flexible extension bar, 150 mm (5.9 inch) long. It fits between a 1/4 inch drive ratchet, spinner or handle and the socket, and lets you reach small fasteners in confined or angled locations where direct access is restricted.

A rigid bar needs a straight line from the handle to the fastener. On a crowded engine bay, an appliance or a machine guard that line is often blocked, and this flexible extension bar is made for those jobs: the socket goes where the fastener is, and the handle stays where you can turn it. Keep this flex extension with your rigid socket extensions and use whichever suits the job in front of you.

A ball detent on the male end grips the socket, and a retention groove at the female drive end secures the connection to your ratchet or handle. The bar is designed and manufactured to DIN3123B and made from chrome vanadium steel, according to Teng Tools. It is not an impact extension: use it as a socket wrench extension on hand tools only.

The bar comes with a metal socket clip for use with a socket rail. Teng Tools lists it in its TM111 set.

What you get: 1 x 1/4 inch drive flexible extension bar, 150 mm (5.9 inch), with a metal socket clip. Ratchet and sockets are not included.

  • FLEXIBLE, 150 MM (5.9 INCH): A 1/4 flexible extension that adds 150 mm (5.9 inch) between a 1/4 inch drive ratchet, spinner or handle and the socket. Teng Tools makes it for access to fasteners in confined or angled locations, where the handle cannot sit in a straight line behind the socket because a bracket, hose or panel is in the way.
  • A ball detent on the male end grips the socket, and a retention groove at the female drive end takes the ball detent of your ratchet or handle to secure the connection. Ratchet, bar and socket stay together as one tool when you feed it in toward a small fastener you can barely see.
  • Designed and manufactured to DIN3123B and made from chrome vanadium steel, according to Teng Tools. This 1/4 drive extension is a hand tool accessory, not an impact extension, so use it with ratchets, spinners and other hand-turned 1/4 inch square drive handles rather than an impact driver.
  • Teng Tools supplies the bar with a metal socket clip for use with a socket rail, so this flexible ratchet extension can sit on the same rail as your 1/4 inch drive sockets instead of getting lost in a drawer. An empty clip shows at a glance that it has not come back from the job.
  • Built for automotive and general engineering work where direct access is restricted: a screw behind trim, a clamp under a cover, a small bolt tucked behind a pipe. Teng Tools lists it in its TM111 set, so it also replaces a lost bar from that set. It works with any 1/4 inch square drive socket and ratchet.
