Value Collection 34848X Size 5 Taper Pin Uncoated Steel

Product Description

The VALUE COLLECTION 34848X is a Size 5 uncoated steel taper pin manufactured to ANSI/ASME B18.8.2 standards. It features a small end diameter of 0.2422 inches and a large end diameter of 0.289 inches, with an overall length of 2.25 inches. Made from C-12L14 steel, this pin is designed for use in mechanical assemblies where a removable, self-locking connection between a shaft and a hub or collar is required. Machinists, tool and die makers, and maintenance technicians use taper pins to secure components in precise alignment. The slight taper creates a wedging action that resists loosening under vibration and load.

This taper pin suits a wide range of industrial and mechanical applications including machine tools, jigs, fixtures, and general assembly work. It is appropriate for both light and moderate load-bearing connections in metal fabrication, maintenance, and repair operations where repeatable disassembly is needed. The standard taper geometry conforms to ANSI/ASME B18.8.2, making it interchangeable with other Size 5 taper pin hardware in production and maintenance environments.

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 5 taper pin replacement or replacement stock for machine tool fixtures, jigs, and general mechanical assemblies requiring a Size 5 taper pin connection.

Installation Notes

Taper pins are typically installed and removed by machinists or maintenance mechanics using a pin punch and hammer or a taper pin reamer to prepare the mating hole. The tapered hole must be reamed to match the pin taper before installation to ensure full contact and proper seating. Always de-energize and lock out equipment before removing or installing taper pins in rotating or load-bearing assemblies. Do not force an oversized pin into an undersized hole, as this can crack hubs or distort bores.
