Use of Fasteners1. Clearance Holes for Fasteners with Screw Thread
2. Length of Projection of Bolt and Screw Ends with Metric (ISO) Screw Thread
Examples:
- hexagon and slotted (castle) nuts : v = nut height + 2P
- prevailing torque nuts : v = nut height + 3P
- nominal length L = griplength Lk + projection length v.
The calculated values have to be rounded off to the next larger standardized length.
