Value Collection MSC67706002X Size 4 Threaded Taper Pin

Product Description

The VALUE COLLECTION MSC67706002X is a Size 4 externally threaded taper pin machined from 303 grade 18-8 stainless steel with a passivated finish. The pin features a 1/4-28 UNF thread form at the small end, a large-end diameter of 0.248 inches, and a neck diameter of 0.198 inches. Pin length is 1.5 inches. The passivated surface treatment improves corrosion resistance without altering the base dimensions. These pins are used by machinists, maintenance technicians, and mechanical assemblers to secure hubs, collars, and components to shafts in applications where removal and reinstallation are required.

Threaded taper pins are well suited to light- and medium-duty mechanical assemblies in industrial, marine, and food-processing environments where stainless steel is specified for corrosion resistance or sanitary requirements. The 1/4-28 thread allows the pin to be driven in by hand or with a drift and then extracted with a nut without damaging the receiving hole. Typical installations include shaft-to-collar connections, lever assemblies, and linkage joints where positive location and easy field removal are both priorities.

Key Features

• Size 4 taper pin geometry per AN386 standard
• Large-end diameter of 0.248 inches with maximum diameter tolerance of 0.0013 inches
• 1/4-28 UNF thread for nut-assisted extraction
• 303 grade 18-8 stainless steel construction for corrosion resistance
• Passivated finish enhances surface corrosion protection
• 1.5-inch pin length suits a range of hub and collar thicknesses

Compatibility

Designed as a standard AN386 Size 4 threaded taper pin suitable for use in any application calling for a 1/4-28 threaded taper pin with a 0.248-inch large-end diameter in stainless steel.

Installation Notes

Installation is typically performed by machinists or maintenance mechanics using a taper pin reamer to finish the tapered hole to the correct size before driving the pin. Always power down and lock out any rotating machinery before servicing shaft-to-hub connections. Drive the pin with a suitable drift until fully seated, then thread a nut onto the 1/4-28 thread finger-tight to retain the pin during operation. For extraction, apply the nut and use it to pull the pin free without damaging the bore.
