Value Collection 241058PR Precision Dowel Pin 3/32x1/2 in Grade 8

Product Description

The VALUE COLLECTION 241058PR is a precision dowel pin used to locate, align, and fix components in close-tolerance assemblies. Manufactured from Grade 8 alloy steel with a Rockwell hardness of 50-58 HRC, this pin delivers the strength and dimensional accuracy required in demanding mechanical, tooling, and fixture applications. The 3/32-inch diameter and 1/2-inch overall length conform to ASME B18.8.2, with a diameter tolerance of 0.0002 inches to ensure consistent press or slip fits. One end is beveled and one end is rounded per the ASME standard. Machinists, tool-and-die makers, and maintenance technicians install these pins to maintain repeatable part location across assemblies.

This precision dowel pin is suited for use in jigs, fixtures, dies, and machine components where tight positional tolerances are critical. The double-shear breaking strength of 1,800 pounds makes it appropriate for moderate to high-load alignment applications in both production and maintenance environments. Typical installations include press fits into reamed holes in steel or cast iron components. This pin ships individually but is available with a minimum order quantity of 100 pieces.

Key Features

• ASME B18.8.2 compliant — ensures interchangeability with standard precision dowel hole patterns
• Grade 8 alloy steel construction with 50-58 HRC hardness for wear resistance
• Diameter tolerance of 0.0002 inches for consistent press or slip fit performance
• Double-shear breaking strength of 1,800 pounds
• One beveled end and one rounded end for controlled insertion and seating
• Compact 3/32-inch diameter by 1/2-inch length for small-profile alignment applications

Compatibility

Designed as an ASME B18.8.2 standard precision dowel pin for use in reamed holes sized to accept a 3/32-inch nominal diameter pin in steel, cast iron, and similar tooling-grade base materials.

Installation Notes

Precision dowel pins are typically installed by machinists or tool-and-die professionals using an arbor press or hydraulic press into finish-reamed holes. Inspect hole diameter and surface finish before installation to confirm proper fit class. Never drive pins with impact tools, as this can damage the pin geometry or bore. Follow applicable shop standards and engineering drawings for fit tolerances and press-in depth.
