Value Collection 241487BR Precision Dowel Pin 1x4.5in Grade 8

Product Description

The VALUE COLLECTION 241487BR is a precision dowel pin designed for accurate locating and alignment of mated components in mechanical assemblies. Machined from Grade 8 alloy steel, it measures 1 inch in diameter and 4-1/2 inches in overall length, with a diameter tolerance of 0.0002 inches for tight, repeatable fits. The pin carries a hardness rating of 50-58 HRC, giving it the wear resistance and shear strength required for demanding industrial and tooling applications. End configuration is one beveled end and one rounded end, conforming to ASME B18.8.2. It weighs approximately 1.48 pounds.

This dowel pin is suited for use in jigs, fixtures, dies, molds, and machine frames where precise hole-to-hole registration is required. The large 1-inch diameter and 4-1/2-inch length make it appropriate for heavy-duty tooling setups and structural alignment tasks in manufacturing, maintenance, and fabrication environments. Machinists, tool and die makers, and industrial maintenance technicians are the primary installers. Sold individually.

Compatibility

Designed as a precision OEM-style locating pin for use in standard dowel pin applications requiring a 1-inch nominal diameter hole and ASME B18.8.2 compliance.

Installation Notes

Installation of precision dowel pins typically requires a press fit into a reamed or precision-bored hole; hand or hydraulic press equipment is commonly used. Ensure the receiving hole is clean, deburred, and within tolerance before pressing the pin. Always power down and lock out any associated machinery before performing alignment or fixture work. Follow applicable shop safety and machinery maintenance standards during installation and removal.
