Value Collection MSC67704445X Threaded Taper Pin Size 6

Product Description

The VALUE COLLECTION MSC67704445X is a Size 6 threaded taper pin used to secure components on shafts, hubs, and assemblies where a positive mechanical lock is required. Manufactured from C-12L14 free-machining steel with no coating, this pin features a 5/16-24 threaded end that accepts a nut for positive retention and easy removal. The large end diameter measures 0.339 inches, the neck diameter measures 0.253 inches, and the overall pin length is 3 inches. Maximum diameter tolerance is held to 0.0013 inches, making it suitable for precision-fit applications. It meets AN386 standards.

Threaded taper pins are common in mechanical, industrial, and maintenance applications where assemblies must be disassembled for service without damaging mating parts. The tapered geometry creates a self-locking fit in a matching reamed hole, and the threaded end allows a nut or extractor to pull the pin cleanly from tight bores. This pin is typically installed by machinists, millwrights, and maintenance technicians working on shafts, pulleys, gears, and linkage assemblies in light to medium industrial equipment.

Key Features

• Size 6 taper per AN386 standard geometry
• 5/16-24 threaded end for nut retention and controlled extraction
• Large end diameter of 0.339 inches with a neck diameter of 0.253 inches
• Pin length of 3 inches suits medium-depth hub and shaft installations
• C-12L14 free-machining steel provides consistent dimensional accuracy
• Uncoated finish — inspect mating bore condition before installation

Compatibility

Designed as an AN386-compliant Size 6 threaded taper pin for use in any application requiring a standard reamed taper hole sized for a Size 6 pin with a 5/16-24 threaded end.

Installation Notes

Installation requires a properly reamed taper hole matched to Size 6 pin geometry — never drive a taper pin into an unreamed or undersized hole. Press or lightly drive the pin to seat it in the bore, then thread a nut onto the 5/16-24 end and tighten to secure. For removal, back off the nut and use it as a jack or use a standard pin extractor against the threaded end — do not strike the threaded end directly. Follow applicable machinery safety lockout and tagout procedures before working on any rotating or load-bearing assembly.
