Value Collection MSC67548206X Taper Pin Size 4/0 Steel

Product Description

The VALUE COLLECTION MSC67548206X is a Size 4/0 taper pin made from uncoated C-12L14 steel, designed for precision locating and alignment applications in mechanical assemblies. With a small end diameter of 0.0882 inches and a large end diameter of 0.109 inches, this pin provides a controlled interference fit when driven into a matching tapered hole. Overall length is 1 inch. The controlled diameter tolerances of -0.0007 inches to +0.0013 inches conform to ANSI/ASME B18.8.2, making this pin suitable for production environments where repeatability and dimensional accuracy are required. Machinists, millwrights, and assembly technicians are the primary installers.

This taper pin is used in light-duty to medium-duty mechanical assemblies where components must be precisely located and locked in position on shafts, hubs, or fixtures. The Size 4/0 designation indicates a standardized taper geometry per ANSI/ASME B18.8.2, allowing direct interchangeability with other conforming pins of the same size designation. Common applications include shaft-to-hub locking, gear and pulley alignment, and jig-and-fixture work in industrial and OEM manufacturing settings.

Key Features

• Size 4/0 taper per ANSI/ASME B18.8.2 for standardized fitment
• Small end diameter 0.0882 inches, large end diameter 0.109 inches
• 1 inch overall length suits compact assembly applications
• C-12L14 steel construction provides good machinability and adequate shear strength for light-duty locating use
• Uncoated finish suitable for dry or lightly lubricated environments
• Tight diameter tolerances (-0.0007 / +0.0013 inches) support precise, repeatable alignment

Compatibility

Designed as a standard replacement or production taper pin conforming to ANSI/ASME B18.8.2 Size 4/0 specifications, compatible with any matching tapered hole reamed to the same standard.

Installation Notes

Taper pins are installed by machinists or millwrights using a pin punch and hammer or an arbor press after the mating hole has been reamed to the correct taper with a matching taper reamer. Always de-energize and lock out any machinery before removing or installing locating pins in rotating assemblies. Do not force an oversized pin into an undersized hole, as this can crack hubs or distort bores. Removal is accomplished by driving the pin out from the small end using an appropriately sized pin punch.
