Value Collection SF043020 Precision Dowel Pin 1/8x2 in Grade 8

Product Description

The VALUE COLLECTION SF043020 is a precision dowel pin used to align, locate, and retain components in close-tolerance assemblies. Made from Grade 8 alloy steel with a hardness of 50-58 HRC, this pin delivers the strength and dimensional accuracy required for demanding industrial, tooling, and machining applications. It measures 1/8 inch in diameter and 2 inches in overall length, with a diameter tolerance of 0.0002 inch. One end is beveled for easy insertion and the other is rounded. The pin meets ASME B18.8.2 standards, making it a reliable choice for precision fixturing and alignment work performed by machinists, tool-and-die makers, and mechanical assemblers.

This dowel pin is suited for use in jigs, fixtures, molds, dies, and machine tool assemblies where repeatable part location is critical. Its Grade 8 alloy steel construction provides a double-shear breaking strength of 3,200 pounds, supporting use in moderate to high-load alignment applications. Typical installation environments include production machine shops, toolrooms, and general industrial manufacturing operations requiring tight component registration.

Key Features

• Grade 8 alloy steel construction with 50-58 HRC hardness for wear and shear resistance
• Diameter tolerance of 0.0002 inch for high-precision fit in close-tolerance bores
• Double-shear breaking strength of 3,200 pounds
• One beveled end and one rounded end for controlled insertion
• Meets ASME B18.8.2 fastener standard
• Compact 0.01-pound weight suitable for dense fixture layouts

Compatibility

Designed as an OEM-style precision locating pin for use in jigs, fixtures, dies, molds, and mechanical assemblies requiring a 1/8-inch diameter precision bore per ASME B18.8.2.

Installation Notes

Precision dowel pins are typically installed by machinists or tool-and-die technicians using an arbor press or pin driver. The receiving bore should be reamed to the correct tolerance before installation to avoid damaging the pin or bore. Always de-energize and lock out any machine before servicing or replacing locating pins in active tooling. Do not hammer pins directly without a proper driving tool, as this can compromise dimensional integrity and bore finish.
