Value Collection 241490BR Dowel Pin 1x5 in Alloy Steel Grade 8

Product Description

The VALUE COLLECTION 241490BR is a precision dowel pin machined from Grade 8 alloy steel to ASME B18.8.2 standards. It measures 1 inch in diameter and 5 inches in overall length, with a diameter tolerance of 0.0002 inches for tight, repeatable locating in precision assemblies. One end is beveled and one end is rounded, following standard ASME end-type geometry. The pin is hardened to 50-58 HRC and carries a double-shear breaking strength of 204,000 pounds. Machinists, toolmakers, and mechanical assemblers install this type of pin to align mating components and maintain positional accuracy under load.

Precision dowel pins in this size range are used in heavy industrial fixtures, dies, molds, and machine tool assemblies where component alignment and shear resistance are critical. The 1-inch diameter and 5-inch length suit applications requiring substantial load transfer between aligned bores. This pin is appropriate for both new assembly work and replacement of worn or damaged locating pins in existing tooling and equipment.

Key Features

• ASME B18.8.2 standard geometry ensures dimensional conformance and drop-in compatibility with compliant bored holes
• Grade 8 alloy steel construction provides high strength and wear resistance
• 50-58 HRC hardness rating supports use in demanding locating and shear applications
• Double-shear breaking strength of 204,000 pounds for heavy-load assemblies
• Diameter tolerance of 0.0002 inches delivers precise, consistent fit
• One beveled end and one rounded end for straightforward installation and alignment

Compatibility

Designed as an OEM-style replacement or new-installation precision dowel pin for machinery, tooling, dies, and fixtures bored to ASME B18.8.2 specifications for a 1-inch nominal diameter pin.

Installation Notes

Precision dowel pins are typically installed by machinists or toolmakers using an arbor press or hydraulic press to drive the pin into a reamed bore. Confirm bore diameter and finish meet ASME B18.8.2 tolerances before installation. Never strike the pin directly with a hammer, as this can damage the end geometry or distort the bore. De-energize and lock out all equipment before servicing any assembly that contains locating pins.
