Value Collection MSC67704809X Threaded Taper Pin Size 7

Product Description

The VALUE COLLECTION MSC67704809X is a Size 7 threaded taper pin machined from C-12L14 steel and left uncoated for standard industrial use. The pin features a 3/8-24 threaded end that accepts a nut to secure the pin in place after installation, preventing back-out under load or vibration. The large end diameter measures 0.407 inches with a maximum diameter tolerance of plus or minus 0.0013 inches, providing close-fit precision in tapered holes. Overall pin length is 4.5 inches. This type of fastener is installed by machinists, millwrights, and maintenance mechanics in mechanical assemblies where a removable, load-bearing pin connection is required.

Threaded taper pins are used across a wide range of mechanical and structural assemblies including shaft-to-hub connections, gear and pulley mounting, fixture alignment, and machine frame joints. The Size 7 designation refers to the standard taper pin taper series and corresponding hole dimensions. Typical applications include general manufacturing equipment, agricultural machinery, and conveyor or drive assemblies where the pin must be retained securely. The 3/8-24 thread accommodates a standard nut and washer for positive retention.

Installation Notes

Installation is performed by machinists or maintenance mechanics using a taper pin reamer to prepare the tapered hole to the correct Size 7 specification before driving the pin. Always confirm hole taper and diameter match the pin size before pressing. Secure the threaded end with an appropriate 3/8-24 nut and washer to prevent back-out. Depressurize or de-energize any associated machinery before servicing fasteners in rotating or load-bearing assemblies.
