Value Collection MSC67552927X Taper Pin Size 9 Steel

Product Description

The VALUE COLLECTION MSC67552927X is a Size 9 uncoated steel taper pin designed for precision alignment and assembly applications across industrial and mechanical systems. Manufactured from C-12L14 free-machining steel, this pin features a small end diameter of 0.5182 inches and a large end diameter of 0.591 inches, with an overall length of 3.5 inches. The taper profile creates a secure, self-locking fit when driven into matched taper-reamed holes. Machinists, millwrights, and maintenance technicians install these pins to secure hubs, collars, and pulleys to shafts or to align mating components during assembly and repair work.

This taper pin is suited for general industrial maintenance, machine tool repair, power transmission assemblies, and precision fixturing applications. The C-12L14 steel grade offers good machinability and is appropriate for moderate-load, non-corrosive environments. It is sold individually and is well-suited for bench-level repair work as well as production assembly operations where consistent taper geometry is required to maintain alignment under load.

Key Features

• Size 9 taper pin with 0.5182-inch small end diameter and 0.591-inch large end diameter
• 3.5-inch overall length suitable for medium-depth hub and collar applications
• C-12L14 free-machining steel for reliable machinability and consistent tolerances
• Minimum diameter tolerance of -0.0007 inches and maximum of +0.0013 inches per ANSI/ASME B18.8.2
• Uncoated finish for bare-metal fitment in standard dry or lightly lubricated assemblies
• Sold as a single pin, compatible with standard taper-reamed holes

Compatibility

Designed as a standard ANSI/ASME B18.8.2-compliant Size 9 taper pin, suitable for use in any application requiring a matched Size 9 taper-reamed hole.

Installation Notes

Taper pins are typically installed by machinists or millwrights using a pin punch and hammer or a taper pin reamer set to prepare the mating hole. Always de-energize and lock out equipment before removing or installing taper pins in rotating assemblies. Ensure the mating hole is properly reamed to the correct taper before driving the pin to avoid galling or splitting the workpiece. A removal punch applied to the small end is the correct method for extraction.
