Value Collection MSC67704841X Threaded Taper Pin Size 7

Product Description

The VALUE COLLECTION MSC67704841X is a Size 7 threaded taper pin machined from C-12L14 steel with an uncoated finish. It features a 3/8-24 external thread and measures 5 inches in pin length with a large-end diameter of 0.407 inches and a neck diameter of 0.315 inches. Taper pins are precision fasteners used to secure hubs, collars, and levers to shafts or to align mating components in mechanical assemblies. Machinists, millwrights, and maintenance technicians install these pins where a removable, self-locking fit is required without permanent fastening methods.

This threaded taper pin is suited for general industrial and mechanical applications where AN386 standard fitment is required. The threaded end accepts a nut to allow controlled extraction and reinstallation, making it practical in assemblies that require periodic disassembly. Typical applications include shaft-to-hub connections, fixture alignment, and light structural pinning in manufacturing, maintenance, and repair environments. The C-12L14 free-machining steel grade provides good machinability and consistent dimensional control.

Key Features

• Size 7 taper pin with 5-inch pin length for positive shaft and hub engagement
• 3/8-24 threaded end allows nut-assisted extraction without damage to the assembly
• Large-end diameter of 0.407 inches with a maximum diameter tolerance of 0.0013 inches
• C-12L14 free-machining steel grade for consistent dimensional accuracy
• Conforms to AN386 standard for taper pin dimensional requirements
• Uncoated finish suitable for controlled environments or field application of protective coatings

Compatibility

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

Installation Notes

Installation is typically performed by machinists or millwrights using a taper pin reamer to prepare the mating hole to the correct taper before driving the pin. De-energize and lock out all equipment before working on any shaft or rotating assembly. A properly fitted taper pin should seat firmly by hand pressure and final light driving before the nut is applied to the threaded end. Do not force an oversized pin into an undersized hole, as this can crack hubs or distort bores.
