Value Collection MSC67706846X Threaded Taper Pin Size 8

Product Description

The VALUE COLLECTION MSC67706846X is a Size 8 threaded taper pin machined from 303 grade 18-8 stainless steel with a passivated finish. The pin measures 3 inches in length with a large end diameter of 0.49 inches and features a 7/16-20 threaded end for positive retention and removal. Taper pins are precision fasteners used to secure hubs, collars, levers, and similar components to shafts, transmitting torque without additional hardware. The passivated stainless steel construction resists corrosion in wet or chemically active environments. This part meets AN386 standards and is suited for applications where material cleanliness and corrosion resistance are required.

Threaded taper pins in this size range are commonly installed in light industrial, mechanical, and trade service applications where a reliable, removable shaft-to-component connection is needed. The 7/16-20 threaded end accepts a standard nut for positive retention, making controlled disassembly straightforward during maintenance or field service. Typical installation scenarios include motor couplings, pump assemblies, valve actuators, and similar rotating or reciprocating machinery components.

Compatibility

Designed as a standard Size 8 threaded taper pin suitable for use in shaft-to-hub connections and mechanical assemblies requiring AN386-compliant hardware in stainless steel.

Installation Notes

Threaded taper pins are typically installed by machinists or millwrights using a reamed taper hole sized to match the pin taper. Ensure the mating hole is properly reamed and free of burrs before driving the pin. A retaining nut should be applied to the threaded end and torqued according to the assembly specification for the specific application. Always de-energize or lock out equipment before servicing any rotating assembly.
