Value Collection 241145PR Precision Dowel Pin 3/16x1.5in Grade 8

Product Description

The VALUE COLLECTION 241145PR is a precision dowel pin manufactured from Grade 8 alloy steel to ASME B18.8.2 standards. It measures 3/16 inch in diameter and 1.5 inches in overall length, with one beveled end and one rounded end. Hardness is rated at 50-58 HRC, and the pin is held to a diameter tolerance of 0.0002 inches, making it suitable for close-tolerance locating and alignment applications. Breaking strength is 7,200 pounds in double shear. Machinists, toolmakers, and maintenance technicians install these pins in fixtures, jigs, dies, and precision assemblies where repeatable part location is required.

This dowel pin is used in industrial and manufacturing environments where tight dimensional control is critical. Typical applications include aligning mold halves, locating fixture plates, and positioning components in die sets or machine assemblies. The ASME B18.8.2 specification ensures dimensional conformance for interchangeable use in standard precision-pin applications across metalworking and fabrication shops.

Key Features

• ASME B18.8.2 compliant for standardized dimensional interchangeability
• Grade 8 alloy steel construction with 50-58 HRC hardness for wear resistance
• Diameter tolerance of 0.0002 inches for close-tolerance fit applications
• 7,200-pound double-shear breaking strength
• One beveled end and one rounded end for guided insertion and seating
• 3/16 inch diameter x 1.5 inches length suits compact locating applications

Compatibility

Designed as an OEM-style precision locating pin for use in fixtures, dies, jigs, and machine assemblies requiring ASME B18.8.2 compliant 3/16-inch diameter dowel pins.

Installation Notes

Precision dowel pins are typically pressed or driven into reamed holes by machinists or maintenance technicians using an arbor press or soft-faced mallet. The mating hole should be reamed to the appropriate tolerance class for the intended fit — transition or interference — before installation. Never force a pin into an undersized or unreamed hole, as this can damage the pin or the bore. Disengage all power and secure moving components before servicing any fixture or assembly that uses dowel pins for alignment.
