Is there any formula that show the relationship between Nut and it's wrench. for example a nut with size 1/2" has a wrench No. 22
is there any formula that show relationship between 1/2" and 22?
What is Anodised Aluminum?
When I first started work in the electrical trade there were switches and sockets that had metal plates brightly finished with a hard decorative coating (plated, painted - or whatever) in various basic colours - red - blue - green - bronze - etc, and they were described as 'anodised aluminium'.
Happy Solstice!
Today marks the winter solstice here in the north, the sun sets rises as far “south east” as it will get.  If you are in the southern hemisphere this is your summer solstice  YAY!
For me and those in these parts, we can see the days grow longer and for a couple months see the cold grow stronger. Â Been pretty cold so far this winter, but not too much snow. Â For you south of here in the mid-Atlantic states – I do feel your pain. Â I will say I am rather impressed though. Â I was watching some traffic cams out of Tyson’s Corner VA at a big intersection and while there was some problems, for the most part people did really well driving in the snow. Â Well done!
I’ll be back!
