A built-in directional lever lets you switch between tightening and loosening without removing the head from the fastener.
Interchangeable head design
This standalone head pairs with compatible 1 inch drive handles, breaker bars, and torque accessories you already own.
DIN 3122D compliance
Manufactured to meet the DIN 3122D standard, this component satisfies rigorous dimensional and performance benchmarks recognized across professional workshops.
Push-button socket release
The built-in socket release function lets you swap sockets with one hand by pressing the button on the head.
Read the full description
Built for professionals who work with large fasteners every day, this Teng Tools 1 inch drive head delivers dependable performance on heavy equipment, commercial trucks, and industrial assemblies.
The 24-tooth mechanism provides a 15-degree swing arc, so you can advance fasteners in tighter quarters than many coarser-tooth alternatives allow. A directional lever on the body switches between clockwise and counterclockwise operation instantly, and a push-button on the head ejects sockets without tools or prying.
At 165 mm (6.5 in) in overall length, the compact footprint lets you store this head alongside your 1 inch drive accessories without eating up drawer space. It conforms to the DIN 3122D standard, giving you confidence that critical dimensions and load paths meet professional benchmarks.
Whether you are torquing lug nuts on Class 8 trucks, servicing mining equipment, or assembling structural bolts in a fabrication shop, this head pairs with your existing handles and extensions to keep your workflow fast and your fastener connections secure.
