Remember the good old days when Whitworth was the standard thread

mercredi 19 août 2015

Remember the days when you could go to the hardware store, pick up a few nuts and bolts in Whitworth and then grab yourself a sausage sandwich for $2.50.....wait a second...that was on Sunday:?:?.

So I needed a half inch nut for a Frankenstein jig I was making (I had a 1/2" UNC bolt to suit), here is the post if you want to read more of my craziness

Sometimes I get bolts mixed up, so I took the bolt with me (I've made that mistake before). So being Sunday there really is only one option, you know the place, the one that's painted green. I get to the bolt section and they have a thread gauge, so I grab my bolt out and thread it into the 1/2UNC slot, lucky I had the bolt because my store is small and 1/2 bolts were very limited.

OK time to grab a half inch nut, zinc will do, and get home (well after I get my sausage...OK 2....what, I like to support my local community fire brigade...don't judge me:C).

I get home, drill the 1/2" hole in steel and go to thread the nut on.....it won't go...I check the threads, turn it around, nothing, it goes maybe half a turn and then binds. I drive all the way back and same deal, no nuts fit my bolt, but it will thread perfectly onto their gauge.

So what is wrong. Well believe it or not their Zinc nuts and bolts are Whitworth threads, any other bolt size would have been fine (1/2" UNC and Whitworth don't match, one is 13TPI and the other is 12TPI. Now I have nothing against Whitworth threads, in fact this is good news for me (a lot of my machines have Whitworth), but I don't quite understand why such a large company is using this thread count as standard (it's not like the bolt head sizes are Whitworth).

General staff had no idea, and only one experienced guy eventually used the word Whitworth, so clearly not many people buy just a nut or just a bolt in 1/2" from this place.

Anyway, it's a bit of a rant, but it's also to let you know that if your looking for a half inch nut or bolt in Whitworth, (as unlike the other sizes UNC will not fit), or I'm guessing any other size in Whitworth, then there is probably a place just around the corner you can buy it from. Who said Whitworth was old fashioned and no longer used (your average home handyman is probably using them all the time:U)

Cheers,
