Shoulder screws ISO 7379 are cost-saving construction elements for a wide variety of different uses.
The maximum tightening torque must not be defined by strength class 12.9, it is instead limited by the relatively small bearing points (shoulders) and by the recesses at the transition point from d1 to d2 and d3.
The ISO standard sheet allows for screws with or without knurled head.
Standard deviation:
- no information about the concentricity 2 IT 13 and 2 IT 10
- the official ISO standard sheet has the following dimensions for d1 - d2: 6.5-M5 / 13-M10 / 25-M20
- the dimensions 4-M3 and M4-M5 are not included in the official ISO standard sheet
- Cylinder head shoulder bolts GN 732.1
