Value Collection MSC67706721X Size 7 Threaded Taper Pin

Product Description

The VALUE COLLECTION MSC67706721X is a Size 7 threaded taper pin manufactured from 303 grade 18-8 stainless steel with a passivated finish. The pin features a 3/8-24 threaded end and measures 0.407 inches at the large end diameter, with a neck diameter of 0.315 inches and a pin length of 3.5 inches. The passivated stainless steel construction provides corrosion resistance in demanding environments. This fastener is used in mechanical assemblies where precise, removable alignment and locking of mating components is required. Machinists, maintenance technicians, and assembly professionals install this type of pin where the taper creates a self-locking fit between hub and shaft or other aligned components.

Threaded taper pins are commonly used in industrial machinery, tooling fixtures, and mechanical assemblies where components must be repeatedly removed and reinstalled with consistent alignment. The 3/8-24 threaded end allows a nut to be used for controlled installation and removal without damaging the pin or the mating parts. This pin is suitable for both original equipment assembly and maintenance replacement in applications requiring AN386 standard compliance.

Compatibility

Designed as an AN386-standard Size 7 threaded taper pin suitable for use in mechanical assemblies, tooling fixtures, and industrial equipment that accept a 3/8-24 threaded taper pin of this taper size and diameter.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a pin driver or press, with the threaded end receiving a nut to drive the pin fully into the tapered bore. Always de-energize and lock out equipment before servicing any pinned assembly. Ensure the mating hole is clean, properly reamed to the correct taper, and free of burrs before installation. Use the threaded nut and a puller or press for removal to avoid damaging the pin or the surrounding material.
