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.
