Value Collection MSC67553123X Taper Pin Size 9 6 in Steel

Product Description

The VALUE COLLECTION MSC67553123X is a Size 9 steel taper pin used to secure components on shafts, hubs, and assemblies where a precise, removable connection is required. Machined from C-12L14 free-machining steel and left uncoated, it measures 6 inches in overall length with a small end diameter of 0.4662 inches and a large end diameter of 0.591 inches. The tapered geometry provides a self-locking fit when driven into a matching reamed hole. This pin is installed by machinists, millwrights, and maintenance technicians working on mechanical assemblies across industrial and trade applications.

This taper pin is suited for use in mechanical power transmission assemblies, shaft-to-hub connections, and general machine component alignment. It is appropriate for both light and moderate load applications where a taper-fit fastener is required. The C-12L14 steel grade offers good machinability and adequate strength for standard industrial fitment scenarios. This pin is sold individually and is intended for installations where the mating hole has been reamed to the correct taper using a matching taper reamer.

Key Features

• Size 9 taper pin with 6-inch overall length for medium-length shaft and hub connections
• Small end diameter of 0.4662 inches and large end diameter of 0.591 inches for a defined taper geometry
• Machined from C-12L14 free-machining steel for consistent dimensional accuracy
• Uncoated finish — no coating thickness to account for in precision fits
• Diameter tolerance of -0.0007 inches minimum and +0.0013 inches maximum per ANSI/ASME B18.8.2
• Conforms to ANSI/ASME B18.8.2 standard for taper pins

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 9 taper pin replacement for mechanical assemblies requiring a 6-inch taper pin with matching reamed holes at the specified small and large end diameters.

Installation Notes

Installation is performed by machinists or maintenance technicians using a taper reamer to prepare a matched hole before driving the pin. De-energize and lock out all equipment before beginning work on any mechanical assembly. Drive the pin with a hammer and punch; do not force beyond hand-fit engagement without confirming hole alignment and taper match. Removal is performed by driving from the small end using a pin punch of appropriate diameter.
