Value Collection MSC67706044X Threaded Taper Pin Size 4

Product Description

The VALUE COLLECTION MSC67706044X is a Size 4 threaded taper pin manufactured from 18-8 Grade 303 stainless steel with a passivated finish. The pin measures 2 inches in length with a large end diameter of 0.248 inches and a neck diameter of 0.198 inches. The 1/4-28 threaded end allows for controlled extraction using a standard nut, making removal straightforward in assemblies where the pin must be serviced periodically. Passivation enhances corrosion resistance by removing free iron from the surface. This pin meets AN386 standards and is suited for use by machinists, maintenance technicians, and assembly professionals working in precision mechanical applications.

Threaded taper pins are used in mechanical assemblies where a removable, self-locking locating or fastening pin is required. The tapered profile wedges into a matching reamed hole to resist rotation and axial movement. This pin is appropriate for light to medium-duty applications in equipment assemblies, jigs, fixtures, and shaft-to-hub connections where periodic disassembly is anticipated. The passivated stainless steel construction makes it suitable for environments with moisture exposure or mild corrosive conditions.

Key Features

• Size 4 taper pin profile with 0.248-inch large end diameter for precise hole fitment
• 1/4-28 threaded end enables controlled extraction with standard hardware
• Grade 303 18-8 stainless steel construction provides corrosion resistance
• Passivated finish further enhances surface corrosion resistance
• Meets AN386 standard for threaded taper pins
• Maximum diameter tolerance of 0.0013 inches for consistent fit in reamed holes

Compatibility

Designed as a replacement or original-installation threaded taper pin for mechanical assemblies requiring a Size 4 taper pin with a 1/4-28 threaded extraction end, conforming to AN386 dimensional standards.

Installation Notes

Installation is performed by machinists or mechanical maintenance technicians. The mating hole must be reamed to the correct taper before driving the pin to ensure proper seating and load transfer. Power down and de-energize any equipment before servicing pinned assemblies. Use the threaded end with a standard nut and puller to extract the pin without damaging the host material during removal.
