M20-2.5 x 20 Cup Point 18-8 Stainless Steel Metric Socket Set Screw is a DIN 916 style stainless set screw for metric power-transmission details.

Protected marine-adjacent deck mechanisms may call for stainless metric set screws, with final material selection based on exposure. European drawings often call this geometry DIN 916; ISO 4029 superseded it with matching cup point dimensions. Confirm the metric thread, length, cup diameter, and hex key before substituting another set screw.
