Bolt identification

[losh1971]

Don't talk to me about BSW....... I have the odd BSW spanner in my cab and I have never worked out why it would say 1/4 yet the size is around 13mm. I just had to buy a stack of nuts and bolts in BSW for my Howard. I took in nearly every fastener, dropped off early in the day and picked the order up after work. I didn't even know the fasteners were BSW until I started using the new ones.

What we thinking lads?
Add a couple more washers?

Just try it, chances are there is extra thread in the head.

Also another update, I can tighten down the original bolt in the thread and remove the Extraction tool now.
So there is no more issue of leaving the extraction tool on the nut.
Its just that I have to use it if I want to take it out and I'm not sure how that translates to the longevity of it=
