Value Collection MSC67702126X Taper Pin Size 5 Ss

Product Description

The VALUE COLLECTION MSC67702126X is a Size 5 taper pin machined from 303 grade 18-8 stainless steel with a passivated finish for corrosion resistance. It measures 2.5 inches in overall length with a small end diameter of 0.237 inches and a large end diameter of 0.289 inches. The tapered profile creates a secure, self-locking fit when driven into a reamed hole, making it a reliable fastening method for shafts, hubs, and machine assemblies. Licensed machinists, millwrights, and maintenance technicians install taper pins where repeatable alignment and positive locking without threading are required.

This taper pin is suited for industrial machinery, mechanical assemblies, and precision equipment where stainless steel is specified for its corrosion and oxidation resistance. The passivated surface treatment further enhances resistance to mild chemical environments and moisture exposure. Typical applications include securing collars to shafts, aligning fixture components, and fastening linkages in food processing, marine, and general manufacturing equipment where stainless fasteners are preferred over carbon steel alternatives.

Key Features

• Size 5 taper pin with 0.237-inch small end diameter and 0.289-inch large end diameter
• 2.5-inch overall length and pin length for medium-depth hub and shaft assemblies
• 303 grade 18-8 stainless steel construction for corrosion and oxidation resistance
• Passivated finish provides additional surface protection against moisture and mild chemicals
• Conforms to ANSI/ASME B18.8.2 for dimensional and tolerance compliance
• Diameter tolerance range of -0.0007 to +0.0013 inches for precise fitment

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 5 taper pin for use in reamed taper-pin holes sized to accept a 0.237 to 0.289-inch taper across a 2.5-inch length in mechanical assemblies.

Installation Notes

Taper pins are installed by a machinist or millwright after the mating hole has been properly reamed to the correct taper specification. Ensure the assembly is fully de-energized and secured before driving or extracting the pin. A taper pin reamer and a suitable drift punch or pin driver are standard tools for installation and removal. Do not force an oversized pin into an under-reamed hole, as this can crack the hub or distort the bore.
