Value Collection 261187PR Dowel Pin 1/4x2 in Alloy Steel Gr8

Product Description

The VALUE COLLECTION 261187PR is a standard pull out dowel pin used to align, locate, and retain mating components in precision assemblies. Machined from Grade 8 alloy steel, this pin measures 0.25 inches in diameter and 2 inches in overall length, with a diameter tolerance of 0.0002 inches for consistent, repeatable fits. One end is rounded for guided insertion; the opposite end is threaded to accept a pull-out tool for removal without damage to the bore or surrounding material. Manufactured to ASME B18.8.2. Machinists, tool-and-die technicians, and maintenance mechanics work with this pin in production fixtures, jigs, dies, and general machine assemblies.

This dowel pin is suited for applications requiring precise hole-to-hole alignment in ferrous and non-ferrous assemblies. The threaded pull-out end makes it practical in blind-hole installations where a standard solid pin cannot be extracted with conventional methods. Typical settings include machine tool fixtures, stamping dies, mold components, and general industrial maintenance where part-to-part location must be held tightly under repeated disassembly and reassembly cycles.

Key Features

• Threaded end allows extraction from blind holes without bore damage
• Rounded drive end guides pin into alignment bore cleanly
• Grade 8 alloy steel provides high shear strength for demanding fixture and die applications
• Diameter tolerance of 0.0002 inches supports precise, consistent fits
• Conforms to ASME B18.8.2 standard dimensions
• Lightweight at 0.03 pounds per piece

Compatibility

Designed as an ASME B18.8.2-compliant standard pull out dowel pin for use in any application requiring a 0.25-inch diameter, 2-inch length dowel in a blind or through-hole configuration.

Installation Notes

Installation and removal should be performed by a machinist or qualified maintenance technician familiar with precision fastener practices. Ensure mating bores are reamed to the correct tolerance before driving the pin. Use an appropriate pull-out tool threaded to match the pin end for removal — never attempt to drive the pin out from the threaded end. Verify the assembly is de-energized and all clamping or press forces are released before removing locating pins from live tooling or fixtures.
