Gary Stephenson wroteStill clearing the garage and came across this lock along with some of the shear head fixing bolts.
It always amazed me the amount of variations on those fixings, seeing those sure brings back memories.
Going back the 1980s supply was so erratic I had to make batches with a modified old turret on the lathe- loads of the short csk steel ones for the cell lock flanges.
Chubb did eventually slacken their grip and can remember buying them hassle free probably late 90s. Saved me having hands in mountains of needle-like swarf,drenched in coolant doing very repetitive work- working onsite on the actual locks was by far the more enjoyable part.
You also get some of them in brass for the shrouds and non critical fixings, and sometimes see the bigger steel ones used on rotary deposit safes and cash handling systems, more variations yet again as most of those were much longer.
You’ve got a great mixture of stuff Gary, plus you seem to keep it coming endlessly, when you say “still clearing the garage”, I’m thinking more like “warehouse” !
