M8-1.25 x 8 Cup Point Alloy Steel Metric Socket Set Screw is used where a headless fastener must lock a component without adding an external screw head.

Automation and robotics joints can use the screw for retained knobs, stops, collars, and small adjustment parts. A DIN 916 callout is commonly satisfied by an ISO 4029 cup point socket set screw when the metric size and length match the print. Review the metric diameter, length, cup diameter, and hex key together before substitution.

For hard-to-find metric cup point set screws, Cold Headers can help review uncommon lengths and large-diameter requirements.
