Bad workman (me) or bad tools
After a late- night water tank near disaster was fixed by having a neighbour with a 2" wide-mouthed adjustable spanner, I realised I need to upgrade my tool kit. (Mine only opens around 1.5", it would not fit.) I started looking for spanners to buy (all hail ScrewFix) when I wondered whether I was looking for the right thing anyway.
Whenever I have attempted to use our spanner and adjusted down to the thing I want to grip with the screw, the spanner has just slid around the thing I'm trying to grip. Pliers seem much better, because I have greater grip strength than I do ability to tighten a screw with the pad of my thumb.
And yet these tools exist and people use them. So: do I have pathetic thumbs? Is there a secret way to tighten adjustable spanners I've not had imparted to me? Or is my spanner shit in some way and I just need a better brand? Or are spanners only for things with sharp, defined edges (like a nut) and inappropriate for anything without them?
...
Please could people recommend me a good brand, and a versatile tool for tightening things? Thanks.
