Holo-krome 02127 Pull Out Dowel Pin 12x100mm Grade 8

Product Description

The HOLO-KROME 02127 is a standard pull out dowel pin manufactured from Grade 8 alloy steel with a black luster finish. It measures 12 millimeters in diameter and 100 millimeters in overall length, with one beveled end and one rounded end for controlled insertion and extraction. The diameter tolerance is held to -0.0001 to 0.0001 decimal inches, making it suitable for precision alignment and locating applications in machined assemblies. This pin meets ASME B18.8.5M standards and is appropriate for use by machinists, tool and die makers, and maintenance technicians working on mechanical assemblies requiring repeatable part positioning.

Pull out dowel pins are used in industrial and manufacturing environments where precise component alignment is required and the pin must be retrievable without damage to the mating parts. The beveled end facilitates initial engagement into the mating hole, while the rounded end allows extraction using standard pull-out tooling. This pin is suited for use in jigs, fixtures, machine frames, and assemblies where tight-tolerance location is critical and disassembly is anticipated during maintenance or reconfiguration cycles.

Key Features

• Grade 8 alloy steel construction for high strength and wear resistance
• Black luster finish provides a degree of corrosion resistance and surface uniformity
• One beveled end and one rounded end for guided insertion and pull-out extraction
• Diameter tolerance of -0.0001 to 0.0001 decimal inches for precision fit applications
• Conforms to ASME B18.8.5M fastener standard
• 12mm diameter by 100mm overall length

Compatibility

Designed as an OEM-style replacement or standard-service pull out dowel pin for precision machined assemblies requiring ASME B18.8.5M compliant locating hardware.

Installation Notes

Installation and removal should be performed by a qualified machinist or maintenance technician using appropriate press or pull-out tooling rated for the pin diameter. Always verify mating hole tolerance and surface condition before installation to avoid galling or binding. Do not hammer the rounded end directly, as this can damage the extraction geometry. Follow applicable facility safety procedures when working with press-fit components.
