Value Collection MSC67550400X Size 4 Taper Pin Uncoated Steel

Product Description

The VALUE COLLECTION MSC67550400X is a Size 4 uncoated steel taper pin manufactured to ANSI/ASME B18.8.2 standards. It features a small end diameter of 0.2032 inches and a large end diameter of 0.25 inches, with an overall length of 2.25 inches. Made from Grade C-12L14 steel, this pin is designed for use in mechanical assemblies where a reliable, self-locking connection between a shaft and hub or collar is required. The tapered profile allows the pin to seat securely under load and be driven out for disassembly when needed. Machinists, millwrights, and maintenance technicians install these pins in a wide range of industrial and mechanical applications.

This taper pin is suited for general-purpose industrial assemblies including machine tools, conveyor systems, and shaft-to-hub connections where controlled alignment and removable fastening are priorities. The ANSI/ASME B18.8.2 compliance ensures dimensional consistency across production runs, making it appropriate for both original equipment assembly and field replacement work. The uncoated finish is standard for applications where corrosion exposure is minimal or where a specific coating will be applied post-installation.

Key Features

• Size 4 taper pin per ANSI/ASME B18.8.2 dimensional standard
• Small end diameter of 0.2032 inches with minimum diameter tolerance of -0.0007 inches and maximum of 0.0013 inches
• Large end diameter of 0.25 inches for positive self-locking seating
• Grade C-12L14 steel construction for consistent machinability and shear strength
• Overall length of 2.25 inches suitable for medium-duty shaft and hub assemblies
• Uncoated finish for use in low-corrosion environments or where post-processing will be applied

Compatibility

Designed as an OEM-style replacement or new-installation taper pin for Size 4 tapered holes in mechanical shaft and hub assemblies conforming to ANSI/ASME B18.8.2.

Installation Notes

Taper pins are typically installed and removed by machinists or millwrights using a pin punch and hammer or an arbor press. Always de-energize and lockout the equipment before servicing any shaft or coupling assembly. Ensure the tapered hole is clean and free of burrs before driving the pin to seat; do not force an oversized pin into an undersized hole. Refer to applicable machinery manufacturer guidelines for proper pin size selection relative to shaft diameter and torque load.
