ISO 7379 Shoulder Screws Steel

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
