Value Collection MSC67706804X Threaded Taper Pin Size 8

Product Description

The VALUE COLLECTION MSC67706804X is a Size 8 threaded taper pin machined from 303 grade 18-8 stainless steel with a passivated finish. The pin measures 2.5 inches in length with a large-end diameter of 0.49 inches and a neck diameter of 0.368 inches. It carries a 7/16-20 threaded end for positive retention and is manufactured to AN386 standards. The passivated surface provides corrosion resistance suitable for demanding mechanical assemblies. Machinists, millwrights, and maintenance technicians use this pin to align, lock, or retain mating components in precision assemblies.

This threaded taper pin is used in light-to-medium industrial and mechanical applications where a removable, self-locking alignment or retention fastener is required. The threaded end allows a nut to be applied for secure installation and easier extraction. Typical applications include shaft-to-hub connections, gear assemblies, linkage systems, and machinery frames where precise hole alignment and pin retention are critical. The stainless steel construction makes it appropriate for environments subject to moisture, mild chemicals, or sanitary requirements.

Key Features

• Size 8 taper pin with 0.49-inch large-end diameter and 0.368-inch neck diameter
• 2.5-inch pin length for medium-depth through-hole installations
• 7/16-20 threaded end for nut-driven installation and assisted extraction
• 303 grade 18-8 stainless steel construction for corrosion resistance
• Passivated finish removes free iron and improves surface oxide layer
• Manufactured to AN386 standard for dimensional conformance

Compatibility

Designed as an AN386-standard Size 8 threaded taper pin for use in applications requiring a 7/16-20 threaded taper pin in stainless steel construction.

Installation Notes

Threaded taper pins are installed by a machinist or millwright using a pin driver or press into a reamed taper-pin hole sized to match the pin taper. Always de-energize and lock out any equipment before installing or removing fasteners in rotating or load-bearing assemblies. The threaded end accepts a standard nut to prevent backing out under vibration and to assist in controlled extraction during service. Verify hole alignment and hole finish before driving the pin to avoid galling the stainless steel surface.
