Value Collection 34858X Size 7 Taper Pin Uncoated Steel

Product Description

The VALUE COLLECTION 34858X is a Size 7 uncoated steel taper pin manufactured to ANSI/ASME B18.8.2 standards. It features a small end diameter of 0.357 inches and a large end diameter of 0.409 inches, with an overall length of 2.5 inches. The pin is machined from C-12L14 free-machining steel, which provides consistent dimensional accuracy and reliable performance in mechanical assemblies. Taper pins are used to secure hubs, collars, and levers to shafts, and to align mating components in precision fixtures. Installation is performed by machinists, maintenance technicians, and mechanical assemblers working in industrial and manufacturing environments.

This taper pin is suited for light-to-medium duty fastening applications where a self-locking, removable connection is required. The tapered geometry wedges into a reamed hole to create a firm, repeatable fit. Common applications include shaft-to-hub connections, gear assemblies, and tooling fixtures in industrial machinery. The ANSI/ASME B18.8.2 standard ensures dimensional interchangeability with other conforming taper pin components and reamed holes sized for Size 7 pins.

Key Features

• Size 7 taper pin conforming to ANSI/ASME B18.8.2 dimensional standards
• Small end diameter of 0.357 inches with a tolerance range of -0.0007 to +0.0013 inches
• Large end diameter of 0.409 inches for reliable wedging in tapered reamed holes
• Machined from C-12L14 free-machining steel for consistent accuracy
• Uncoated finish; suitable for indoor and controlled-environment applications
• 2.5-inch overall length for standard shaft and hub connection scenarios

Compatibility

Designed as a standard replacement or specification-grade taper pin for any assembly requiring an ANSI/ASME B18.8.2 Size 7 taper pin in a reamed tapered hole.

Installation Notes

Taper pins are installed by machinists or maintenance technicians using a properly sized taper reamer to prepare the mating hole before driving the pin. Always ensure the reamed hole is clean and free of burrs before seating the pin. Use a pin punch and hammer to drive and remove taper pins; do not use impact tools that could damage the seating surface. Verify the pin size and hole taper match before installation to prevent misalignment or component damage.
