I think my brain has been metricated!
Got job to do on some 25mm square stock, could do it in the 4 jaw but always hankered for a keats fixture. So purchased one from a UK store.
Fitted the stock ok but with only 2 threads biting on the bolts thought I should get some longer bolts.
Drag out the thread gauges and mic, strange size 9.3 mm dia and 1.6mm pitch.
So tried online searches, nothing obvious showing up nearest was a 9mm 1.5, a bit on the small side. Had a look in the shop and found a bolt that fitted, then the penny dropped!!
Its not metric at all just good old 3/8 whit.
Looked for some longer bolts and found some studding, cut to length, jobs a good un!
So I really must stop thinking that everything new must be metric.
