Value Collection MSC67551523X Size 6 Steel Taper Pin

Product Description

The VALUE COLLECTION MSC67551523X is a Size 6 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 0.2474 inches and a large end diameter of 0.341 inches. The tapered profile provides a secure, self-locking fit in matching reamed holes, resisting rotation and axial movement under load. Machinists, millwrights, and maintenance technicians use this pin to locate and retain mating components in shafts, hubs, and mechanical assemblies where repeatable disassembly is required.

This taper pin is suited for general industrial and mechanical applications including shaft-to-hub connections, gear and pulley retention, and fixture alignment in light to medium-duty machinery. The C-12L14 steel grade offers good machinability and consistent dimensional tolerance, making it appropriate for production and MRO environments. It conforms to ANSI/ASME B18.8.2 standards, which ensures dimensional interchangeability with standard taper pin reamers and mating hardware across common tooling setups.

Key Features

• Size 6 taper pin conforming to ANSI/ASME B18.8.2 dimensional standards
• Overall length of 4.5 inches with a uniform taper from 0.2474 inches to 0.341 inches
• C-12L14 free-machining steel for consistent machining and reliable dimensional tolerance
• Minimum diameter tolerance of -0.0007 inches and maximum diameter tolerance of +0.0013 inches
• Uncoated finish suitable for standard dry or lubricated assembly environments
• Self-locking taper geometry eliminates need for additional fasteners in properly reamed holes

Compatibility

Designed as a standard Size 6 taper pin replacement or new installation component for mechanical assemblies requiring ANSI/ASME B18.8.2-compliant taper pins. Proper fitment requires a matching Size 6 taper pin reamer and correctly sized receiving hole.

Installation Notes

Installation should be performed by a qualified machinist or millwright. The receiving hole must be reamed to match the Size 6 taper profile before driving the pin to ensure proper seating and holding force. Disengage and lock out all power sources to the machinery before installation or removal. Use a pin punch and hammer of appropriate size for driving; do not use oversized tools that may damage the small end of the pin or distort the hole.
