Value Collection MSC67702928X Taper Pin Size 8 3in Oal

Product Description

The VALUE COLLECTION MSC67702928X is a Size 8 stainless steel taper pin designed for precision mechanical assemblies where a secure, removable connection between a shaft and hub or similar components is required. Manufactured from 303 18-8 stainless steel with a passivated finish, this pin delivers corrosion resistance well-suited to demanding or moisture-prone environments. It measures 3 inches overall length with a small end diameter of 0.4296 inches and a large end diameter of 0.492 inches. The passivated surface treatment reduces surface oxidation and extends service life in corrosive conditions. Machinists, maintenance technicians, and mechanical assembly professionals install this type of fastener across a range of industrial and mechanical applications.

Taper pins of this size and material grade are used in general mechanical assemblies, machine tool components, and industrial equipment where controlled, repeatable alignment and easy disassembly are required. The tapered geometry self-locks under load and releases cleanly for maintenance access. This pin is appropriate for both light and moderate-duty applications in manufacturing, fabrication, and equipment maintenance environments where stainless steel material compliance is specified.

Key Features

• Size 8 taper pin with 3-inch overall length for medium-scale mechanical assembly applications
• 303 18-8 stainless steel construction provides corrosion resistance in wet or chemically active environments
• Passivated finish reduces surface oxidation and improves long-term durability
• Conforms to ANSI/ASME B18.8.2 dimensional standards for consistent fit and interchangeability
• Minimum diameter tolerance of -0.0007 inches and maximum diameter tolerance of 0.0013 inches for precise fitment
• Self-locking taper geometry seats firmly under load while remaining removable for maintenance

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 8 taper pin for use in mechanical assemblies requiring a 0.4296-inch small end diameter and 0.492-inch large end diameter with a 3-inch pin length.

Installation Notes

Taper pins are installed by machinists or mechanical maintenance technicians using a tapered reamer to prepare the mating hole and a pin punch and hammer to drive the pin to full seat. Always de-energize and lock out equipment before performing any fastener installation or removal. Do not force an oversized pin into an undersized hole, as this can crack hub material or damage bore geometry. Removal is performed from the small-end side using a suitable pin punch.
