M3-0.5 x 50 Cup Point Alloy Steel Metric Socket Set Screw covers larger or smaller metric cup point needs without converting the assembly to inch hardware.

Typical applications include shaft collars and locking collars where the screw seats through the collar wall onto the shaft surface. Set screws load primarily in compression rather than tension, so the governing standards treat hardness and torsional behavior differently than cap screw tensile ratings. Review the metric diameter, length, cup diameter, and hex key together before substitution.

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