Value Collection MP34837 Taper Pin Size 3 Uncoated Steel

Product Description

The VALUE COLLECTION MP34837 is a Size 3 taper pin manufactured from C-12L14 steel in an uncoated finish. Taper pins are precision-machined fasteners used to secure components on shafts, align mating parts, or lock assemblies against rotational or axial movement. This pin has a small end diameter of 0.1878 inches and a large end diameter of 0.219 inches, with an overall length of 1.5 inches. It conforms to ANSI/ASME B18.8.2 dimensional standards. Machinists, millwrights, and maintenance technicians install these pins in mechanical assemblies where a reliable, removable retention method is required.

This taper pin is suited for light-duty mechanical assemblies in both industrial and commercial maintenance applications. Typical uses include securing collars, hubs, and gears to shafts in equipment where the pin can be driven in and removed with a punch and hammer. The C-12L14 free-machining steel grade provides good machinability and consistent dimensional tolerances. This item is sold in a package quantity of 10 pins, making it practical for production runs or stocking in a maintenance crib.

Compatibility

Designed as a standard Size 3 taper pin per ANSI/ASME B18.8.2, compatible with any tapered hole or reamed bore machined to the corresponding Size 3 taper pin specification.

Installation Notes

Taper pins are typically installed by machinists or maintenance mechanics using a pin punch and hammer or an arbor press. The mating bore should be reamed to the correct taper before installation. Always relieve mechanical load and de-energize or lock out the equipment before driving or removing the pin. Do not substitute a taper pin in a straight-pin application, as the taper geometry is required for proper seating and retention.
