[Guest quickeys]

Can anyone advise on how the cuts on keys are actually measured? Are they in millimeters? Are pins measured the same way? Thanks

Also - Mortice key Pin and Pipe's are measured in " GUAGE " Sizes - which in turn can be shown as " mm " sizes . . as follows

 

Guage / MM

 

0 // 8.00 - 8.23

1 // 7.50 - 7.60

2 // 7.00

2.5 // 6.71 - 6.50

3 // 6.4

3.5 // 6.15 - 6.00

4 // 5.89

4.5 // 5.64 - 5.50

5 // 5.38

5.5 // 5.13 - 5.00

6 // 4.88

6.5 // 4.67 - 4.50

7 // 4.47

7.5 // 4.27

8 // 4.06 - 4.00
