Value Collection MSC67705962X Threaded Taper Pin Size 4

Product Description

The VALUE COLLECTION MSC67705962X is a Size 4 threaded taper pin manufactured from 303 grade 18-8 stainless steel with a passivated finish. It features a 1/4-28 threaded end for secure fastening and a large end diameter of 0.248 inches with a neck diameter of 0.198 inches. Meeting AN386 standards, this pin is designed for use in mechanical assemblies where precise alignment and the ability to disassemble components are required. Machinists, maintenance technicians, and assembly professionals install this type of fastener in tooling, fixtures, shafts, and mechanical linkages. The passivated finish enhances corrosion resistance, making it suitable for applications exposed to moisture or mild chemical environments.

This threaded taper pin is suited for industrial and mechanical assembly applications where a removable, self-locking alignment solution is needed. The threaded end allows the pin to be driven out or extracted using a nut and puller without damaging the surrounding material. Typical installation scenarios include aligning hubs to shafts, securing levers to actuator rods, and locating fixture components. The Size 4 designation and AN386 compliance make it a recognized standard fastener across aerospace, industrial, and general machining applications.

Key Features

• Neck diameter of 0.198 inches with a maximum diameter tolerance of 0.0013 inches
• 1 inch pin length for compact alignment and fastening applications

Compatibility

Designed as a standard AN386 Size 4 threaded taper pin for use in mechanical assemblies, tooling fixtures, and shaft alignment applications that require a 1/4-28 threaded extraction interface.

Installation Notes

Threaded taper pins are installed by machinists or mechanical assembly technicians using a taper pin reamer to prepare the tapered hole to the correct size and taper angle before driving the pin. Always ensure the mating hole is properly reamed and deburred before installation to achieve full seating. To remove, thread a nut onto the 1/4-28 end and use a puller or back the nut against a spacer to press the pin free without impact damage. Follow applicable shop standards and engineering specifications for hole preparation and fit tolerances.
