Value Collection MSC67551283X Size 6 Steel Taper Pin

Product Description

The VALUE COLLECTION MSC67551283X is a Size 6 taper pin machined from C-12L14 steel with no surface coating. Taper pins are precision fasteners used to secure hubs, collars, and other components to shafts, providing positive alignment and resistance to rotational movement. This pin has a small end diameter of 0.2942 inches and a large end diameter of 0.341 inches, with an overall length of 2.25 inches. It conforms to ANSI/ASME B18.8.2 dimensional standards, making it a reliable drop-in choice for standard taper pin applications in mechanical assemblies.

This pin is suited for general industrial and mechanical maintenance applications where a standard uncoated steel taper pin is required. Typical uses include securing gears, pulleys, and couplings to shafts in light to medium duty assemblies. It is commonly installed by machinists, maintenance technicians, and millwrights working on production equipment, conveyors, and shaft-driven components. The C-12L14 free-machining steel grade provides good machinability and consistent dimensional tolerance for repeatable fit.

Key Features

• Conforms to ANSI/ASME B18.8.2 standard for taper pins
• C-12L14 free-machining steel construction for consistent dimensional accuracy
• Small end diameter of 0.2942 inches with a minimum tolerance of -0.0007 inches and maximum tolerance of 0.0013 inches
• Large end diameter of 0.341 inches for secure tapered engagement in mating holes
• 2.25-inch overall length suitable for standard Size 6 taper pin applications
• Uncoated finish — no added surface treatment that could affect fit in precision bores

Compatibility

Designed as an OEM-style replacement or standard fitment for any assembly requiring an ANSI/ASME B18.8.2 Size 6 taper pin with a 0.2942-inch small end diameter and 0.341-inch large end diameter.

Installation Notes

Taper pins are typically installed by machinists or maintenance technicians using a pin punch and hammer or an arbor press. Before installation, ensure the mating taper-reamed hole is clean, properly sized, and free of burrs. Always de-energize and lock out equipment before servicing any shaft or rotating assembly. Do not force an oversized pin into an undersized bore, as this can crack the hub or distort the shaft.
