Specification
Shoulder screw: Steel, blackened, tensile strength 1200 N/mm2 (strength class 12.9)
Adapter dimension d1 ground

  Information
ISO 7379 shoulder screws are cost-saving construction components for a wide variety of different uses.
Maximum tightening torque should not be defined by strength class 12.9, for 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.
Standard deviation: the official ISO standard sheet has the following dimensions for d2 - d1: M5-6.5 / M10-13 / M20-25
Other DIN metric fasteners available upon request.
