Value Collection 34838X Taper Pin Size 3 2 Inches Steel

Product Description

The Value Collection 34838X is a Size 3 steel taper pin designed for precise shaft-to-hub alignment and locking applications in mechanical assemblies. Manufactured from C-12L14 free-machining steel in an uncoated finish, this pin measures 2 inches in overall length with a small end diameter of 0.1774 inches and a large end diameter of 0.219 inches. The tapered profile creates a self-locking fit when driven into a matching reamed hole, resisting loosening under vibration and load. Machinists, millwrights, and maintenance technicians install these pins in production and repair environments where repeatable, precise positioning is required.

Size 3 taper pins are commonly used in light-to-medium duty mechanical assemblies including gear hubs, collars, levers, and couplings. The standard taper ratio allows the pin to seat securely without adhesive or additional hardware. This pin conforms to ANSI/ASME B18.8.2, making it suitable for applications where dimensional compliance to published standards is required. The uncoated steel finish is appropriate for indoor or protected environments where corrosion exposure is limited.

Key Features

• Size 3 taper pin per ANSI/ASME B18.8.2 dimensional standard
• C-12L14 free-machining steel construction for consistent machinability
• Small end diameter of 0.1774 inches with tight tolerance control (-0.0007 / +0.0013 inches)
• Large end diameter of 0.219 inches for positive self-locking seating
• 2-inch overall length suits a wide range of hub and collar thicknesses
• Uncoated finish for direct use or secondary plating and coating processes

Compatibility

Designed as a standard ANSI/ASME B18.8.2-compliant Size 3 taper pin for use in any mechanical assembly requiring a reamed taper pin hole sized to this standard.

Installation Notes

Taper pins are installed by machinists or millwrights using a properly reamed tapered hole matched to the pin size. Power down and lock out all equipment before driving or removing taper pins in any rotating assembly. Use a pin driver or soft-faced hammer to seat the pin fully; do not use impact tools that may deform the small end. Remove taper pins by driving from the small end using an appropriate punch.
