Value Collection MSC67550004X Size 3 Steel Taper Pin

Product Description

The VALUE COLLECTION MSC67550004X is a Size 3 taper pin machined from C-12L14 steel and left uncoated. Taper pins are precision-ground fasteners used to secure hubs, collars, and other components onto shafts, holding position against rotational and axial loads. The pin has a small end diameter of 0.1722 inches and a large end diameter of 0.219 inches, with an overall length of 2.25 inches. Manufactured to ANSI/ASME B18.8.2 standards, this pin is intended for use by machinists, millwrights, and maintenance technicians who require reliable, repeatable alignment and assembly in mechanical assemblies.

This taper pin is suited for light-to-medium duty mechanical assemblies in industrial and commercial maintenance applications. Common use cases include securing hand wheels, gears, and couplings to shafts in machine tools, conveyors, pumps, and general power transmission equipment. The C-12L14 free-machining steel grade supports clean installation in pre-reamed taper holes. This pin is appropriate wherever an ANSI/ASME B18.8.2-compliant Size 3 taper pin is specified.

Key Features

• ANSI/ASME B18.8.2 standard compliance for dimensional consistency and interchangeability
• C-12L14 free-machining steel construction for smooth seating in reamed holes
• Small end diameter of 0.1722 inches with a minimum tolerance of -0.0007 inches and maximum tolerance of 0.0013 inches
• Large end diameter of 0.219 inches provides positive locking taper engagement
• Uncoated finish — suitable for dry or lubricated assemblies where coating buildup is not acceptable
• 2.25-inch overall length fits standard Size 3 taper pin applications

Compatibility

Designed as an OEM-style replacement or direct-fit taper pin for any mechanical assembly requiring an ANSI/ASME B18.8.2 Size 3 taper pin with a 0.1722-inch small end diameter and 0.219-inch large end diameter.

Installation Notes

Taper pins are installed by machinists or maintenance technicians using a properly sized taper pin reamer to prepare the hole before driving the pin. Always power down and de-energize any connected equipment before disassembly or reassembly. Drive the pin with a pin punch and hammer until the pin seats firmly; do not over-drive, as this can deform the receiving bore. Removal is performed by driving the pin out from the small end using an appropriately sized punch.
