Choosing a scaffold wrench
A scaffold wrench has to match the nuts and bolts you run on scaffold frames, couplers and structural steel. The Teng Tools PGW1922 is a double-ended ratcheting construction wrench with fixed 19 mm and 22 mm hex ends, made for scaffold assembly and structural bolting in metric.
What to look for
- Fastener size: each end of this wrench is a fixed metric hex size, so check that your fasteners are 19 mm or 22 mm before you choose it.
- Fixed ends instead of adjustable jaws: fixed hex ends give a positive fit with no jaw slip. That matters when you are working overhead or in a confined scaffold bay.
- Ratcheting action: you drive the fastener with a back-and-forth stroke instead of a full swing, and you can reverse the stroke without lifting the wrench off the fastener.
- Length and weight: at 315 mm (12.4 in) overall and 463 g, the wrench fits in one hand and generates enough torque for most structural connections without a cheater bar.
- Two sizes on one tool: one dual-ended wrench takes the place of two separate wrenches. Your belt is lighter, your pouch stays organized, and you spend less time looking for the right size.

When the PGW1922 is the right choice
This wrench suits repetitive bolting with 19 mm and 22 mm fasteners. Examples include tightening dozens of connections on a steel erection job, running nuts on scaffold couplers, assembling scaffold frames and servicing heavy equipment. In that kind of work, the ratchet saves time because you do not have to lift and refit the wrench on every stroke.
It is aimed at ironworkers, scaffolders, millwrights and mechanical tradesmen who work in metric every day.
When to choose a different size
If your project uses fasteners other than 19 mm or 22 mm, this pairing will not fit them. The PGW1922 is one wrench in a range of metric sizes. Pick the pairing that matches the fasteners on your current project, or build your own collection across the range.
