1/2 Inch Drive Impact Extension Bar

The Teng Tools 920021N is a 1/2 inch drive impact extension bar, 125 mm (5 inch) long, built to DIN standard for reliable compatibility and durability under impact.

An extension puts distance between the impact wrench and the socket. At 5 inch, this 1/2 inch impact extension reaches past a housing or bracket to a recessed fastener and gives the nose of the gun room to clear the part. It is a straight bar, not a wobble or locking type.

The bar is chrome molybdenum (CrMo) steel for use with power tools, with a black phosphate finish that marks it as an impact accessory. A ring and pin fixing hole on the female end secures it to the air gun, and a ball detent on the male end grips the impact socket. Keep impact socket extensions like this one apart from chrome hand extensions, which are not made for an impact wrench.

Teng Tools lists it as compatible with its sets TTEISK73, TT9207 and TTEISK103. It comes with a metal socket clip for use with a socket rail, and weighs 230 g (8.1 oz).

What you get: one 1/2 inch drive impact extension bar, 125 mm (5 inch), DIN, with a metal socket clip. Impact wrench, sockets, socket rail, retaining pin and retaining ring are not included.

• A 1/2 drive impact extension that adds 125 mm (5 inch) between the impact wrench and the socket. It moves the socket out past a guard, bracket or housing and lets the body of the gun clear the work, while staying short enough to keep the wrench close to the fastener.
• Built to DIN standard for reliable fit under impact. A ring and pin fixing hole on the female end lets you secure the bar to the air gun, and a ball detent on the male end holds the impact socket so it does not drop off on the way to the fastener. The retaining pin and ring are not included.
• Made from chrome molybdenum (CrMo) steel for use with power tools, and designed for impact wrenches in high-torque applications. It is a straight, solid impact extension bar with no wobble end and no safety lock, so it drives the socket straight on the same axis as the anvil.
• The black phosphate finish identifies it as an impact socket accessory at a glance, so it stays with the impact sockets instead of ending up on a hand ratchet. Teng Tools supplies it with a metal socket clip for use with a socket rail, so it hangs next to the sockets it drives.
• Teng Tools lists this extension as compatible with its sets TTEISK73, TT9207 and TTEISK103, so it works alongside the impact sockets in any of those sets. It weighs 230 g (8.1 oz). Impact wrench, sockets and socket rail are not included.
