M8x30 Hexagon socket countersunk head screw stainless steel A2 DIN 7991 PG - 100 pcs.

M8x30 Hexagon socket countersunk head screw stainless steel A2 DIN 7991 PG - 100 pcs.
M8x30 hexagon socket countersunk flat head screw, made of stainless steel designated A2, with a natural finish and no additional coating. The head is designed to sit flush with the component surface in a correctly formed countersink.
The full metric thread covers the working part of the shank and allows the full working length of the screw to be used. A2 stainless steel is used in typical atmospheric conditions and where intermittent contact with moisture occurs. For exposure to chlorides, seawater, acids or other aggressive media, check the required material resistance; grade A4 or another special design may be appropriate.
