A: 17mm

**Q: what is the cut out depth**
A: Sorry I can't answer that without removing the bolt from my door, but what I can tell you is that I ordered the 150mm bolt and the top section that the bolt extrudes from is 35mm in length.

Ok, good value for money

### ⭐⭐⭐⭐ It's was the right size
*by A***R on 2 June 2018*

It was good

### ⭐ Very poor quality
*by G***M on 11 September 2020*

These are extremely poor quality bolts. they are nowhere near 90 degrees, the main face surface is not flat and the latch lever is not straight and wobbles about. Rubbish, avoid.
