Value Collection 241298PR Precision Dowel Pin 7/16x1-1/4 Grade 8

Product Description

The VALUE COLLECTION 241298PR is a precision dowel pin designed for tight-tolerance alignment and locating applications in mechanical assemblies. Manufactured from alloy steel at Material Grade 8, it meets ASME B18.8.2 standards and carries a Rockwell hardness rating of 50-58 HRC. The pin measures 7/16 inch in diameter with an overall length of 1-1/4 inches and holds a diameter tolerance of 0.0002 inches, making it suitable for press-fit and slip-fit applications where positional accuracy is critical. It is installed by machinists, millwrights, and mechanical assemblers in production and maintenance environments.

This dowel pin is used in jigs, fixtures, dies, molds, and machine frames where repeatable part alignment is required. The one beveled end aids in chamfered-hole entry during press installation, while the one rounded end provides a smooth lead-in for hand or arbor-press assembly. Typical applications include aligning mating components in industrial equipment, tooling plates, and precision mechanical subassemblies where positional repeatability must be maintained across assembly and disassembly cycles.

Key Features

• Alloy steel construction at Material Grade 8 for high strength and wear resistance
• 50-58 HRC hardness rating for durability in press-fit applications
• Diameter tolerance of 0.0002 inches for precise hole-to-pin fitment
• Breaking strength of 39,100 pounds in double shear
• One beveled end and one rounded end for controlled installation entry
• Conforms to ASME B18.8.2 fastener standard

Compatibility

Designed as an ASME B18.8.2 precision dowel pin for use in any application requiring a 7/16 inch diameter locating pin with a 1-1/4 inch length in alloy steel Grade 8.

Installation Notes

Installation is performed by machinists or millwrights using an arbor press or hydraulic press sized appropriately for the fit class. De-energize and lock out all equipment before installing or removing dowel pins in live machinery. Ensure the receiving hole diameter and finish conform to ASME B18.8.2 tolerances for the intended fit class before pressing. Do not drive hardened dowel pins with a standard hammer, as this can damage the pin, the bore, or the surrounding component.
