Local bolt shop was clearing out some stuff and I offered to buy one table empty of welding nuts and bolts.
I got a bit more than I bargained for, there was some pretty unusual fasteners, guite a few stainless/copper grounding pins and spades.
But there were 4000 plain pins, made out of stainless A2 (CD-stud welding UT-type pins) 5 mm OD l=8 mm.
What these pins are used for? Can anybody think any alternative use?
Other weird thing is whole lot of ALMG (aluminium) M2,5 M3 and M4 threaded studs and nuts, some are press type. Hard to think other uses than aviation or boats?
There was whole lot more stuff than I was prepared, lucily I pooled with some friends. They basically want weld nuts. But there are probably more that 10K press nuts and studs. Even some odd imperial sizes.
Phew....
