M8-1.25 x 20 Cup Point Alloy Steel Metric Socket Set Screw is part of the deep metric cup point range used in plant rebuilds and OEM assemblies.

Typical applications include shaft collars and locking collars where the screw seats through the collar wall onto the shaft surface. Parts may be marked with ISO 4029, DIN 916, or both, so the thread, length, cup diameter, and hex key should be checked together. For inch drawings, Cup Point Alloy Socket Set Screws keep the same cup-rim holding concept in inch-series sizes. 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.
