Value Collection SF043049 Precision Dowel Pin 3/8x2 in Alloy Steel

Product Description

The VALUE COLLECTION SF043049 is a precision dowel pin used to locate, align, and retain mating components in mechanical assemblies. Manufactured from alloy steel to Material Grade 8, this pin measures 3/8 inch in diameter and 2 inches in overall length. It carries a hardness rating of 50-58 HRC and a double-shear breaking strength of 28,700 pounds, making it suitable for high-load positioning applications. Diameter tolerance is held to 0.0002 inches, ensuring consistent press-fit or slip-fit engagement. The pin features one beveled end and one rounded end per ASME B18.8.2 standards. Machinists, tool and die makers, and maintenance technicians install this type of pin in jigs, fixtures, dies, and precision machine components.

This precision dowel pin is suited for industrial and manufacturing environments where tight dimensional control is required for part alignment and load transfer. Typical applications include fixture plates, mold components, press tooling, and machine frames where repeatable part registration is critical. The Grade 8 alloy steel construction handles demanding shear and compression loads encountered in production machinery and heavy tooling. This pin is sold individually with a minimum order quantity of 100 pieces.

Compatibility

Designed as a standard ASME B18.8.2 precision dowel pin for use in jigs, fixtures, dies, molds, and mechanical assemblies requiring a 3/8-inch diameter locating pin with a 2-inch length.

Installation Notes

Precision dowel pins are typically installed by machinists or millwrights using a press or arbor press for interference-fit applications, or by hand for slip-fit configurations. Clean and deburr the receiving bore before installation to prevent galling. Never drive a hardened pin with a steel hammer directly on the pin end, as this can damage the end geometry or the bore. Verify hole diameter and depth against pin tolerance before pressing to avoid seizing or bore damage.
