Value Collection MSC67552083X Size 7 Steel Taper Pin

Product Description

The VALUE COLLECTION MSC67552083X is a Size 7 uncoated steel taper pin manufactured to ANSI/ASME B18.8.2 standards. The pin features a small end diameter of 0.3154 inches and a large end diameter of 0.409 inches, with an overall length of 4.5 inches. Made from Grade C-12L14 steel, this taper pin is designed for use in mechanical assemblies where a secure, removable connection between a shaft and hub or collar is required. Machinists, maintenance technicians, and industrial assemblers install taper pins to transmit torque and lock components in precise rotational alignment.

This taper pin is suited for general industrial and manufacturing applications including machine tool assemblies, gear hubs, levers, and shaft collars. Its tapered profile allows the pin to seat firmly under load, resisting loosening from vibration and dynamic forces. The uncoated finish makes it appropriate for dry or lightly lubricated environments where coating adhesion or corrosion protection is not a primary requirement.

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 7 taper pin for use in any application requiring a 0.3154 inches small end and 0.409 inches large end tapered fastener.

Installation Notes

Taper pins are typically installed by machinists or maintenance technicians using a tapered reamer to prepare the mating hole and a pin punch or hammer to drive the pin into place. Always ensure the mating hole is reamed to the correct taper before installation to achieve full contact along the pin length. Remove all power and secure rotating machinery before servicing assemblies containing taper pins. Never reuse a taper pin that shows deformation, cracking, or wear at the small or large end.
