countersunk head screws

with hexagon socket, zinc flake, silver, Cr(VI)-free 720 h¹ (red rust SST)+ Topcoat (coefficient of friction 0,09-0,14)

Attention: up to M 20 countersink angle: 90°; from M 22 countersink angle; execute countersink per DIN 74 Form.

Due to their head geometry screws may not reach minimum breaking force acc. to ISO 898-1. Nevertheless they have to comply with the other requirements of the respective grade class acc. to ISO 898-1.

¹ For nominal diameter ≤M 6: 480 h.

Per the norm is the thread length is an auxiliary measurement.

*Thread length 'b' is indicated relating to nominal length 'l': l ≤ 125 / 125 < l ≤ 200 / l > 200 mm.

Depending on the manufacturer, these screws are delivered almost fully threaded!
