Value Collection MSC67549360X Taper Pin Size 1 3in Steel

Product Description

The VALUE COLLECTION MSC67549360X is a Size 1 taper pin machined from C-12L14 steel and supplied in an uncoated finish. Taper pins provide a reliable, self-locking method of securing hubs, collars, and levers to shafts in mechanical assemblies. The pin tapers from a small end diameter of 0.1096 inches to a large end diameter of 0.172 inches over a 3-inch overall length. Conforming to ANSI/ASME B18.8.2, this pin is suited for applications where precise, repeatable alignment and secure fastening are required. Machinists, maintenance technicians, and millwrights install these pins in production and repair work across a wide range of mechanical systems.

Size 1 taper pins are commonly used in light-to-medium duty mechanical assemblies including gear hubs, pulleys, couplings, and lever arms on rotating shafts. The 3-inch length accommodates moderate shaft diameters where standard taper pin engagement depth is required. The C-12L14 free-machining steel grade offers good machinability and is appropriate for non-corrosive indoor environments. This pin is a practical choice for OEM production lines, job shop repairs, and field maintenance situations where ANSI-standard fasteners are specified.

Key Features

• ANSI/ASME B18.8.2 compliant for standardized fit and interchangeability
• C-12L14 free-machining steel grade for consistent dimensional accuracy
• Taper profile provides self-locking engagement without additional fasteners
• Small end diameter 0.1096 inches, large end diameter 0.172 inches
• 3-inch overall length suits a range of standard shaft and hub configurations
• Uncoated finish — suitable for dry or lightly lubricated indoor assemblies

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 1 taper pin for use in mechanical assemblies requiring a 3-inch, self-locking taper pin fastener.

Installation Notes

Taper pins are installed by machinists or maintenance technicians using a taper pin reamer to prepare the mating hole, followed by driving the pin with a pin punch and hammer. Always de-energize and lock out equipment before servicing any rotating shaft assembly. Ensure the tapered hole is reamed to the correct Size 1 taper before driving the pin to avoid splitting the hub or damaging the shaft. Do not force an oversized pin into an under-reamed hole.
