Value Collection MSC67704205X Threaded Taper Pin Size 5

Product Description

The VALUE COLLECTION MSC67704205X is a Size 5 threaded taper pin machined from C-12L14 steel and left uncoated. It features a 0.287-inch large-end diameter and a 4-inch pin length, with a 1/4-28 threaded end for positive retention in the assembly. Taper pins of this type are used to secure hubs, collars, and machine components to shafts, transmitting torque and preventing rotational slip. The tapered body self-aligns during installation, making it a reliable fastening method in precision assemblies. This pin meets AN386 standards and is suitable for general industrial, aerospace, and mechanical maintenance applications.

This taper pin is used in applications where a removable, self-locking shaft connection is required. Typical install scenarios include securing gear hubs to shafts, aligning coupling flanges, and fixing levers or arms in machine tool and industrial equipment assemblies. The 1/4-28 threaded end allows a nut to be driven against the small end to lock the pin in place and to aid in extraction during disassembly. Both maintenance technicians and precision machinists will encounter this pin size in production and repair work.

Key Features

• Size 5 taper pin with 0.287-inch large-end diameter and 4-inch length
• 1/4-28 threaded end for positive locking and assisted removal
• C-12L14 free-machining steel construction for consistent dimensional accuracy
• Uncoated finish suitable for standard indoor mechanical assemblies
• Meets AN386 standard for taper pin dimensions and tolerances
• Maximum diameter tolerance of 0.0013 inches for precise fitment

Compatibility

Designed as a standard AN386-compliant Size 5 threaded taper pin for use in shafts, hubs, collars, and flanges drilled and reamed to accept a Size 5 taper pin bore.

Installation Notes

Installation is typically performed by machinists or mechanical maintenance technicians using a taper pin reamer to prepare the mating hole before driving the pin. Always de-energize and lock out the machine before installing or removing taper pins from rotating shafts. Drive the pin from the small end toward the large end using a pin punch and hammer, and thread the retaining nut onto the 1/4-28 end to secure. Do not force an oversized pin into an unprepared or worn bore.
