Value Collection MSC67551689X Size 7 Steel Taper Pin

Product Description

The VALUE COLLECTION MSC67551689X is a Size 7 uncoated steel taper pin designed for precision alignment and fastening applications in mechanical assemblies. Manufactured from C-12L14 steel, this pin features a small end diameter of 0.383 inches and a large end diameter of 0.409 inches, with an overall length of 1.25 inches. The tapered profile allows the pin to seat firmly under load, resisting loosening from vibration. Machinists, maintenance technicians, and millwrights install these pins to align mating components such as hubs, collars, and shafts in both light and heavy industrial settings. Tolerances conform to ANSI/ASME B18.8.2.

This taper pin is suited for use in general industrial machinery, tooling fixtures, and mechanical assemblies where repeatable component alignment is required. The C-12L14 free-machining steel composition provides good machinability and consistent dimensional accuracy across the tapered profile. It is appropriate for both new installations and replacement of worn or damaged pins in existing assemblies. Minimum order quantity is 10 units.

Installation Notes

Taper pins are typically installed and removed by machinists or maintenance technicians using a pin punch and hammer or an arbor press. Ensure mating holes are properly reamed to the correct taper before driving the pin to seat. Always remove load and de-energize or lock out the machine before servicing pinned assemblies per applicable LOTO procedures. Do not reuse a pin that shows deformation or wear at the tapered seating surface.
