M3-0.5 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.

Water-treatment mechanisms and damp equipment housings use stainless set screws where uncoated alloy hardware is a poor fit. DIN 916 and ISO 4029 references should be checked with the thread, length, cup diameter, and hex key shown here. For inch drawings, Cup Point 18-8 Socket Set Screws keep the material family in inch-series sizes. Confirm the metric thread, length, cup diameter, and hex key before substituting another set screw.

For hard-to-find stainless metric cup point set screws, Cold Headers can help review uncommon sizes and service requirements.
