M20-2.5 x 20 Cup Point Alloy Steel Metric Socket Set Screw is a headless internal-hex set screw for locking collars, hubs, and controls on metric shafts.

OEM metric assemblies use cup point socket set screws where repeatable holding contact matters more than external wrench access. European drawings frequently call this screw DIN 916; ISO 4029 superseded that standard with matching dimensional geometry for this cup point form. 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.
