Tightening countersunk
A protrusion length h of 1 ℓ0+1 mm is required for countersunk sections.
A bit protrusion length ℓ1 is required when tightening as shown in the figure. The bit protrusion length depends on factors such as the driver model and Y pipe model so consult us for advice when countersunk (flush) sections must be tightened.

<Example> M3 X 15 L pan-head screws (30A)
h = 15 - 4 = 11 mm
- For Sems (with spring-washers) set the bottom length from the washer as ℓ.
