Value Collection 34856X Taper Pin Size 7 Uncoated Steel

Product Description

The Value Collection 34856X is a Size 7 uncoated steel taper pin used to secure components on shafts, align mating parts, and provide precise, repeatable positioning in mechanical assemblies. Machined from C-12L14 steel, this pin features a small end diameter of 0.3778 inches and a large end diameter of 0.409 inches, with an overall length of 1.5 inches. The tapered profile locks under load without fasteners, making it a reliable choice for maintenance, repair, and OEM assembly work across industrial and mechanical applications.

This taper pin is suited for light-to-medium duty mechanical assemblies where shaft-to-hub connections, gear mounting, or component alignment require a standard, removable fastener. Machinists, millwrights, and maintenance technicians install this pin in environments ranging from production machinery to general fabrication. The Size 7 designation and ANSI/ASME B18.8.2 compliance make it a direct match for applications that call out a standard taper pin by size number.

Key Features

• Size 7 taper pin per ANSI/ASME B18.8.2 standard
• C-12L14 steel construction for consistent machinability and strength
• Small end diameter: 0.3778 inches; large end diameter: 0.409 inches
• 1.5-inch overall length suitable for standard shaft and hub assemblies
• Uncoated finish — compatible with applications requiring bare metal or field-applied coatings
• Diameter tolerance: -0.0007 inches minimum, +0.0013 inches maximum

Compatibility

Designed as an OEM-style and replacement taper pin for mechanical assemblies requiring a Size 7 ANSI/ASME B18.8.2 standard taper pin in uncoated steel.

Installation Notes

Taper pins are typically driven into a tapered, reamed hole using a pin punch and hammer, and removed by driving from the small end. Power down and de-energize any equipment before servicing shaft assemblies. Verify that the mating hole is reamed to the correct ANSI/ASME B18.8.2 taper specification before installation. A machinists hammer and properly sized taper pin reamer are standard tools for this work.
