I was looking at replacing some of the hardware and simultaneously replacing the mounting hardware. I have downloaded the official Laser parts diagrams. Now all screw sizes are imperial, and I have to find the nearest metric size. Apparantly size 10 is 4.8mm. But 5/8" = 16mm is not a normal screw size readily available in 316 A4 stainless. How critical is the length of e.g. the screws to mount the cleat for the traveller line? Could I cause an internal puncture?
