I’ve had a question on “Adjustable pliers”, or a “grip wrench” here. How’s the best way to adjust it, so that you hold the pipe or the nut or the object you’re clamping tight enough, but not too tight?

Basically, it’s fairly simple to use once you get to grips with it. It’s almost like a pair of pliers in action, but there is a bar here which is adjustable by turning this thread in here. As I turn this, it increases the angle and that makes it tighter. If I unscrew the fastener at the end, it becomes slacker like that.
For example, I’ve bought two items here today that you might be using it on. It could be on the car exhaust, it could be on something around the house, a tube or a pipe. There’s a circular spacer, which could be a piece of tube if it was longer. Again, you can see there it needs adjusting to hold it. There’s a lever here, which then releases the plier, the mole grip, or the wrench.

You wind the handle in here, which moves the bar. You can then clamp it. If it’s tight enough, fine. If it’s a little bit loose (you can see here it’s not quite gripping it) and it can slip, release it, and tighten it half-quarter of a turn until it grips nicely, but maybe without crushing or damaging the item. Alternatively, if you’ve got a nut, again it could be the exhaust of the car or somewhere underneath, you can hold it in there. As it is, that won’t quite close, so it needs a bit more adjustments. You’ll hear a click when it does fasten tightly. That now is secure on there. You could either file it, undo it or whatever. Then press the release lever. Out it comes. Very useful tool for your tool bag.
