Value Collection 261191PR Pull Out Dowel Pin 1/4 X 2-1/4 in

Product Description

The VALUE COLLECTION 261191PR is a standard pull out dowel pin manufactured from Grade 8 alloy steel and conforming to ASME B18.8.2. The pin measures 0.25 inches in diameter and 2.25 inches in overall length, with a diameter tolerance of 0.0002 inches for precise, repeatable alignment. One end is rounded and the other end is threaded, which allows controlled extraction from blind holes without damaging the mating bore. Machinists, tool-and-die technicians, and precision assembly mechanics install this type of pin where disassembly access is limited and driven removal is not practical.

Pull out dowel pins of this type are used in jigs, fixtures, dies, and precision machined assemblies where components must be accurately located and periodically disassembled for maintenance or tooling changes. The threaded pull end allows a slide hammer, threaded extractor, or draw bolt to be engaged for controlled removal. This pin is suited for light to moderate duty locating applications in both production and maintenance environments across manufacturing, tool-making, and mechanical assembly trades.

Key Features

• ASME B18.8.2 standard compliance ensures dimensional interchangeability with conforming bores
• Grade 8 alloy steel construction provides high tensile strength and hardness suitable for precision locating duty
• Diameter tolerance of 0.0002 inches supports tight, repeatable fits
• One rounded end for guided insertion; one threaded end for controlled extraction
• Compact 0.03-pound weight suits high-volume fixturing and multi-pin assemblies

Compatibility

Designed as an ASME B18.8.2-compliant standard pull out dowel pin suitable for use in precision-bored holes requiring a 0.25-inch nominal diameter locating pin with a threaded extraction feature.

Installation Notes

Installation and removal should be performed by a qualified machinist or tooling technician. Verify bore diameter and surface finish before pressing the pin to avoid galling or seizing. Use a thread-compatible extractor or draw bolt engaged on the threaded end for removal — do not attempt to drive a pull out pin from the threaded end. Ensure the mating assembly is fully de-energized and unloaded before removing locating pins from active fixtures or dies.
