Value Collection MSC67552646X Taper Pin Size 8 Steel

Product Description

The VALUE COLLECTION MSC67552646X is a Size 8 uncoated steel taper pin manufactured to ANSI/ASME B18.8.2 standards. It features a small end diameter of 0.3776 inches and a large end diameter of 0.492 inches, with an overall length of 5.5 inches. The pin is made from C-12L14 grade steel, a free-machining alloy well suited to precision mechanical assemblies. Taper pins are used to secure hubs, collars, and other components to shafts, providing a reliable, self-locking connection that resists rotation and axial movement. Installation and removal is straightforward with standard pin drivers or reamers, making these pins a practical choice for maintenance and production work.

This taper pin is intended for use in mechanical assemblies where a removable, precision fit fastener is required. Typical applications include securing gears, pulleys, and collars to shafts in light to medium industrial equipment, machine tools, and power transmission assemblies. The Size 8 designation follows ANSI/ASME B18.8.2 sizing conventions, ensuring compatibility with standard taper-reamed holes of the corresponding size. The uncoated finish is appropriate for dry or lightly lubricated indoor environments where corrosion resistance is not a primary concern.

Key Features

• ANSI/ASME B18.8.2 standard compliance ensures dimensional consistency with taper-reamed tooling
• C-12L14 free-machining steel grade provides good strength and machinability
• Taper design creates a self-locking fit that resists axial and rotational movement
• 5.5-inch overall length suits deeper hubs and longer shaft engagement applications
• Uncoated finish allows direct inspection and easy dimensional verification before installation
• Diameter tolerance range of -0.0007 inches to +0.0013 inches for controlled fit

Compatibility

Designed for use in standard Size 8 taper-reamed holes conforming to ANSI/ASME B18.8.2. Consult the standard for hole preparation specifications and tolerances before installation.

Installation Notes

Taper pins are typically installed and removed by machinists or maintenance technicians using a pin driver, punch, or taper pin reamer set. The receiving hole must be reamed to the correct taper before installation to achieve proper seating and locking action. Always de-energize and lock out equipment before installing or removing taper pins from rotating assemblies. Do not force a taper pin into an improperly prepared hole, as this can damage the pin, the bore, or both.
