Material: Stainless steel 1.4301 (AISI 304).

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.

– The stainless steel version is not included in the ISO. Due to the
material, the strenght is lower.

Fastening Torque:

Because of the small contact areas and the recesses, the tightening
torque is much smaller than the torque for a standard stainless steel
bolt A2-70 of the same thread size. Also, the strength of the contact
areas of the corresponding parts must be considered.
