Value Collection MSC67550160X Size 3 Taper Pin 4 in Steel

Product Description

The VALUE COLLECTION MSC67550160X is a Size 3 taper pin machined from C-12L14 free-machining steel and supplied in an uncoated finish. It measures 4 inches overall length with a small end diameter of 0.1358 inches and a large end diameter of 0.219 inches, conforming to ANSI/ASME B18.8.2 standards. Taper pins are precision fasteners used to secure hubs, collars, levers, and other components to shafts, preventing rotational or axial movement. The controlled diameter tolerances — minimum of -0.0007 inches and maximum of 0.0013 inches — ensure a reliable interference fit when driven into a matched tapered hole.

This taper pin is suited for general industrial and mechanical assembly applications including pump assemblies, gear drives, conveyor components, and light machinery where a removable yet secure shaft-to-hub connection is required. The C-12L14 steel grade offers good machinability and consistent dimensional accuracy, making these pins a practical choice for production environments and repair work alike. They are sold individually per package, with a minimum order quantity of 10 units.

Key Features

• Size 3 taper pin per ANSI/ASME B18.8.2 standard
• 4 inches overall length with controlled small and large end diameters
• C-12L14 free-machining steel for consistent dimensional accuracy
• Uncoated finish suitable for standard indoor mechanical assemblies
• Diameter tolerances of -0.0007 inches minimum and +0.0013 inches maximum for reliable interference fit

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 3 taper pin replacement or new installation fastener for use in any application requiring a matched Size 3 tapered reamed hole.

Installation Notes

Taper pins are typically installed by machinists or maintenance technicians using a reamed tapered hole sized to match the pin specification. Power down and de-energize any equipment before disassembly or fastener replacement. Drive the pin into the hole using a pin punch and hammer; removal is accomplished by driving from the small end. Never force an oversized pin into an undersized hole, as this can crack hubs or distort bores.
