Value Collection 241235PR Precision Dowel Pin 5/16x2-1/4 Grade 8

Product Description

The VALUE COLLECTION 241235PR is a precision dowel pin designed for accurate alignment and location of mating components in mechanical assemblies. Manufactured from Grade 8 alloy steel, this pin measures 5/16 inches in diameter and 2-1/4 inches in overall length, with a tight diameter tolerance of 0.0002 inches to ensure precise fitment. The hardness rating of 50-58 HRC provides excellent resistance to wear and deformation under load. With a double-shear breaking strength of 20,000 pounds-force, it is suited for demanding industrial, tooling, and machining applications. Machinists, toolmakers, and mechanical assemblers commonly install this type of pin during fixture and die work.

This dowel pin is used in applications where repeatable, accurate part alignment is required across assemblies, jigs, fixtures, dies, and molds. The combination of one beveled end and one rounded end simplifies installation by guiding the pin into the bore without damage to the workpiece. It is appropriate for both production machining environments and maintenance or repair scenarios where component repositioning accuracy is critical. It is sold individually but subject to a minimum order quantity of 100 pieces.

Key Features

• Grade 8 alloy steel construction with 50-58 HRC hardness for wear resistance under high-stress conditions
• Diameter tolerance of 0.0002 inches for precise bore-to-pin fitment
• Double-shear breaking strength of 20,000 pounds-force for high-load alignment applications
• One beveled end and one rounded end for guided installation without workpiece damage
• Conforms to ASME B18.8.2 standard for precision dowel pins
• 5/16-inch diameter by 2-1/4-inch length suits a wide range of tooling and fixture bores

Compatibility

Designed as an OEM-style precision locating pin for use in mechanical assemblies, jigs, fixtures, dies, and molds requiring ASME B18.8.2 compliant precision dowel pins in a 5/16-inch diameter bore.

Installation Notes

Installation is typically performed by machinists or toolmakers using an arbor press or similar controlled-force tool. Always ensure the receiving bore is clean, deburred, and dimensionally verified before pressing the pin into place. Do not strike the pin directly with a hammer, as this can damage the end geometry and affect fit accuracy. Follow applicable machine shop safety procedures and shut down any powered equipment before performing alignment pin work on active machinery.
