Value Collection 241481BR Precision Dowel Pin 1x3.5 in Grade 8

Product Description

The VALUE COLLECTION 241481BR is a precision dowel pin machined from Grade 8 alloy steel for high-load, tight-tolerance alignment applications. It measures 1 inch in diameter and 3.5 inches in overall length, with a diameter tolerance of 0.0002 inches, making it suitable for precision fixture, jig, and machinery assembly work. The pin is rated at 204,000 pounds breaking strength in double shear and carries a Rockwell hardness of 50-58 HRC. End configuration is one beveled end and one rounded end per ASME B18.8.2 standards. Machinists, millwrights, and tool-and-die technicians are the primary installers.

This dowel pin is used in industrial and commercial manufacturing environments where repeatable part alignment is critical. Typical applications include locating machine components, aligning die sets, and securing fixture plates where high shear loads are expected. The 1-inch diameter and 3.5-inch length suit heavier structural assemblies and large-bore tooling setups. The Grade 8 alloy steel construction holds up in environments subject to vibration, impact, and cyclic loading.

Key Features

• 1-inch diameter with 0.0002-inch diameter tolerance for precision fit
• 204,000-pound double-shear breaking strength for high-load alignment duty
• 50-58 HRC hardness for wear and deformation resistance
• One beveled end and one rounded end for guided installation
• Conforms to ASME B18.8.2 fastener standard
• Grade 8 alloy steel construction for demanding industrial use

Compatibility

Designed as an OEM-style precision locating pin for industrial fixtures, jigs, die sets, and machinery assemblies requiring ASME B18.8.2 compliant 1-inch diameter dowel pins.

Installation Notes

Dowel pins of this diameter are typically pressed or driven into reamed holes by machinists or millwrights using an arbor press or hydraulic press. Power down and de-energize all machinery before installation or removal. Hole diameter and surface finish should be verified against the pin tolerance before pressing to avoid galling or bore damage. Consult applicable machinery or fixture engineering drawings for fit class requirements.
