Value Collection MSC67704643X Threaded Taper Pin Size 7

Product Description

The VALUE COLLECTION MSC67704643X is a Size 7 threaded taper pin machined from C-12L14 steel in an uncoated finish. It features a 3/8-24 threaded end, a large-end diameter of 0.407 inches, and a pin length of 2.5 inches. Taper pins are precision fasteners used to secure hubs, collars, and mechanical assemblies to shafts, providing reliable angular and axial positioning. The threaded end allows for controlled extraction with a standard nut, making removal straightforward without damaging mating components. This pin meets AN386 standards and is suited for mechanical, industrial, and maintenance applications where repeatable alignment and removability are required.

Threaded taper pins are commonly installed in rotating machinery, linkage assemblies, pump impeller hubs, and general mechanical assemblies across industrial and trade settings. The Size 7 designation and 0.407-inch large-end diameter place this pin in a mid-range fitment category suited for moderate-load applications. Machinists, millwrights, and maintenance technicians typically install these pins during equipment assembly or scheduled maintenance intervals where precise component positioning is critical.

Key Features

• Size 7 taper pin with 0.407-inch large-end diameter
• 2.5-inch pin length provides adequate engagement depth for mid-range assemblies
• 3/8-24 threaded end enables controlled extraction without component damage
• C-12L14 steel construction offers good machinability and consistent dimensional tolerances
• Meets AN386 standard for taper pin geometry and tolerancing
• Maximum diameter tolerance of 0.0013 inches for precise interference fit

Compatibility

Designed as an AN386-compliant Size 7 threaded taper pin for use in standard taper-reamed holes in mechanical assemblies requiring a 0.407-inch large-end diameter and 3/8-24 threaded extraction.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a taper reamer to prepare the mating hole before driving the pin. De-energize and lockout all power sources before servicing any rotating or pressurized assembly. Drive the pin from the small end using a suitable drift or pin press, and thread a nut onto the 3/8-24 end to extract the pin during removal. Do not force an oversized pin into an improperly reamed hole, as this can crack hubs or distort bores.
