M3-0.5 x 3 Cup Point 18-8 Stainless Steel Metric Socket Set Screw is a headless internal-hex fastener for locking collars and hubs in wet metric equipment.

Pharma equipment, clean fixtures, and stainless process details may specify this material family for policy and service reasons. European drawings often call this geometry DIN 916; ISO 4029 superseded it with matching cup point dimensions.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.
