Value Collection MSC67548321X Size 3/0 Taper Pin

Product Description

The VALUE COLLECTION MSC67548321X is a Size 3/0 taper pin manufactured from C-12L14 steel with an uncoated finish. It features a small end diameter of 0.1094 inches and a large end diameter of 0.125 inches, with an overall length of 0.75 inches. The tapered geometry creates a self-locking fit when driven into a matching reamed hole, securing components such as shafts, hubs, collars, and levers against axial or rotational movement. This pin conforms to ANSI/ASME B18.8.2 standards, making it a recognized fastener choice for precision mechanical assemblies across industrial, maintenance, and manufacturing applications.

Taper pins of this size class are commonly used in light-duty shaft-to-hub connections, jigs, fixtures, and machine component alignment. The Size 3/0 designation indicates a very small pin suited to compact assemblies where space is limited. Machinists, millwrights, and maintenance technicians typically install these pins in production tooling, instrument mechanisms, and general mechanical assemblies. The C-12L14 free-machining steel grade provides consistent dimensional accuracy and reliable shear strength for low-to-moderate load applications.

Key Features

• Conforms to ANSI/ASME B18.8.2 standard for taper pins
• C-12L14 free-machining steel for consistent dimensional accuracy
• Self-locking taper geometry eliminates need for secondary fasteners
• Uncoated finish suitable for dry or lubricated mechanical environments
• Diameter tolerance range of -0.0007 inches to +0.0013 inches for precise fitment

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 3/0 taper pin for use in any mechanical assembly requiring a matching reamed taper hole of the corresponding size class.

Installation Notes

Installation is performed using a pin punch and hammer or an arbor press; always ream the mating hole to the correct taper before driving the pin. Disengage power and relieve any mechanical load on the assembly before removing or installing taper pins. Do not force an oversized pin into an undersized hole, as this can crack hubs or distort bores. Removal is accomplished by driving the pin out from the small end using an appropriately sized drive punch.
