Value Collection 261355PR Pull Out Dowel Pin Alloy Steel

Product Description

The VALUE COLLECTION 261355PR is a standard pull out dowel pin machined from Grade 8 alloy steel to ASME B18.8.2 specifications. This pin measures 0.5 inches in diameter and 3.5 inches in overall length, with a diameter tolerance of 0.0002 inches for precise, repeatable alignment in close-tolerance bores. One end is rounded and one end is threaded, allowing the pin to be extracted from blind holes using a standard puller or threaded rod. Machinists, toolmakers, and maintenance technicians use pull out dowel pins to accurately locate and align machine components, jigs, fixtures, and die sets where disassembly and reassembly must be repeated without loss of positional accuracy.

This pin suits industrial and manufacturing environments where close-tolerance doweling is required in blind or semi-blind hole applications. The threaded extraction end eliminates the need to drive the pin out from the back side, which is especially useful in thick or solid machine members. Typical applications include fixture plates, mold bases, press tooling, and precision assembly jigs. It is sold individually and is appropriate for shop floor, tool room, and MRO replacement use.

Key Features

• Grade 8 alloy steel construction for high shear strength and hardness
• ASME B18.8.2 compliance ensures dimensional consistency and interchangeability
• 0.0002-inch diameter tolerance supports tight, repeatable fits in precision bores
• Threaded end allows extraction from blind holes without back-driving
• Rounded opposite end for guided insertion without chamfer damage to bore
• Sold as a single pin, suitable for spot replacement or low-volume tooling work

Compatibility

Designed as an ASME B18.8.2 standard-compliant pull out dowel pin for use in any application requiring a 0.5-inch diameter precision dowel with a threaded extraction end in blind hole configurations.

Installation Notes

Installation is typically performed by machinists or toolmakers using a press or mallet; the bore should be reamed to the proper tolerance before pin insertion to ensure fit. Always verify hole depth and thread engagement length before pressing the pin to final position. When extracting, use a correctly sized threaded puller to avoid damaging the bore or the pin threads. Follow applicable shop safety procedures and ensure the workpiece is securely fixtured before pressing or extracting.
