Value Collection MSC67553008X Taper Pin Size 9 Steel

Product Description

The VALUE COLLECTION MSC67553008X is a Size 9 uncoated steel taper pin manufactured from C-12L14 free-machining steel. It measures 4.5 inches in overall length with a small end diameter of 0.4974 inches and a large end diameter of 0.591 inches. Taper pins are precision fasteners used to secure hubs, collars, and mechanical assemblies to shafts, preventing rotational or axial movement. The slight taper along the pin body allows it to wedge firmly into a reamed hole, providing a self-locking fit without adhesives or secondary fasteners. Machinists, millwrights, and maintenance technicians install these pins during assembly and repair of rotating equipment.

This taper pin is suited for general industrial, mechanical, and maintenance applications where a reliable, removable shaft-to-hub connection is needed. Typical uses include securing pulleys, gears, levers, and couplings to shafts in light to medium-duty machinery. The C-12L14 steel grade offers good machinability and is appropriate for applications that do not require corrosion resistance. The uncoated finish makes it straightforward to inspect for dimensional accuracy prior to installation.

Key Features

• Size 9 taper pin with 0.4974-inch small end diameter and 0.591-inch large end diameter
• 4.5 inches overall length suitable for medium-depth hub and collar applications
• C-12L14 free-machining steel construction for consistent dimensional accuracy
• Meets ANSI/ASME B18.8.2 dimensional standards for interchangeable fitment
• Diameter tolerance range of -0.0007 to +0.0013 inches for controlled press fit
• Uncoated finish simplifies visual inspection before and after installation

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 9 taper pin for use in any application requiring a reamed tapered hole to that specification.

Installation Notes

Installation requires a properly reamed tapered hole sized to ANSI/ASME B18.8.2 Size 9 specifications. Drive the pin with a hammer and pin punch, ensuring the assembly is fully secured in a vise or fixture before driving. To remove, drive the pin out from the small end using a punch sized smaller than the pin diameter. Always wear appropriate eye protection when driving or removing taper pins.
