M3-0.5 x 30 Cup Point 18-8 Stainless Steel Metric Socket Set Screw is suited to compact stainless assemblies where the drive must be accessed from the end.

Water-treatment mechanisms and damp equipment housings use stainless set screws where uncoated alloy hardware is a poor fit. The A2-family reference is useful for cross-checking imported callouts, while this catalog line remains 18-8 stainless steel. Confirm the metric thread, length, cup diameter, and hex key before substituting another set screw.

Cold Headers supports imported equipment rebuilds where the replacement screw must preserve the original metric callout.
