Material: Steel strength 12.9, partially black oxide finish.

Screws with precision fit cylinder for multiple usage. These screws have
the usual differences to the norm ISO 7379, like it is common on the
market.

Note:

These screws have the usual differences to the norm ISO 7379, like it is
common on the market:

– Ø 4 mm and Ø 5 mm are not included in the ISO.

– Ø 6 mm instead of ISO Ø 6.5 mm.

– Ø 12 mm instead of ISO Ø 13 mm.

– Ø 24 mm instead of ISO Ø 25 mm.

– Concentricity 2 IT 13 and 2 IT 10 may vary.

Fastening Torque:

Because of the small contact areas and the recesses, the tightening
torque is much smaller than the torque for a standard bolt with strength
12.9 of the same thread size. Also, the strength of the contact areas of
the corresponding parts must be considered.
