Value Collection 261343PR Dowel Pin 0.5x2.5 in Alloy Steel Gr8

Product Description

The VALUE COLLECTION 261343PR is a standard pull out dowel pin machined from Grade 8 alloy steel to ASME B18.8.2 standards. It measures 0.5 inches in diameter and 2.5 inches in overall length, with a diameter tolerance of 0.0002 inches for precise press-fit alignment in mating bores. One end is rounded for guided insertion and the other end is threaded to accept a puller tool for controlled extraction without damage to the bore or surrounding components. Machinists, tool-and-die technicians, and maintenance professionals use this pin where tight positional tolerance and repeatable disassembly are both required.

This pull out dowel pin is suited for fixturing, jig construction, machine assembly, and tooling applications where components must be accurately aligned and periodically disassembled. The threaded extraction end eliminates the need to drive the pin out from the blind side, making it practical in assemblies where reverse access is limited. Typical installations include production fixtures, press tooling, die sets, and precision machine frames in industrial and manufacturing environments.

Key Features

• ASME B18.8.2 standard ensures consistent dimensional and tolerance compliance
• Grade 8 alloy steel construction provides high shear strength for demanding load conditions
• Diameter tolerance of 0.0002 inches supports precision press-fit alignment
• Threaded end accepts standard puller tooling for non-destructive extraction
• Rounded lead end guides pin into bore without marring mating surfaces

Compatibility

Designed as an OEM-style replacement or direct-fit component for applications conforming to ASME B18.8.2 standard pull out dowel pin specifications in 0.5-inch diameter bores.

Installation Notes

Installation and removal are typically performed by machinists or maintenance technicians using an arbor press or hammer with a proper drift for insertion and a slide-hammer puller threaded into the extraction end for removal. De-energize and lock out all machinery before installing or removing dowel pins in any powered assembly. Verify bore diameter and surface finish before pressing the pin to avoid galling or bore damage. Follow applicable ASME and facility safety standards for press-fit fastener handling.
