M8-1.25 x 45 Cup Point Alloy Steel Metric Socket Set Screw gives engineers a specific alloy steel metric set screw size for controlled replacement work.

Couplings and hubs often rely on cup point set screws because the rim concentrates contact at the selected location. The cup rim concentrates load and may leave a witness ring or shallow indentation on the shaft, which is part of the holding method. Cup Point Alloy Set Screws with Nylon Insert are an inch-series option when a self-locking feature is specified. Review the metric diameter, length, cup diameter, and hex key together before substitution.

Cold Headers helps distributors, OEM teams, and plant maintenance groups match metric diameter, pitch, length, and drive size.
