Holo-krome 02117 Pull Out Dowel Pin 12x50mm Grade 8

Product Description

The HOLO-KROME 02117 is a standard pull out dowel pin designed for precision alignment and locating applications in mechanical assemblies. Manufactured from Grade 8 alloy steel with a black luster finish, this pin delivers high shear strength and resistance to wear. It measures 12 mm in diameter and 50 mm in overall length, with a diameter tolerance of -0.0001 to 0.0001 inches for tight, reliable fits. One end is beveled and the other is rounded, making insertion and removal straightforward in production or maintenance environments. Machinists, tool and die makers, and maintenance technicians are the primary installers.

This dowel pin is suited for use in jigs, fixtures, dies, and precision machined assemblies where repeatable part location is required. It conforms to ASME B18.8.5M and DIN 6325 standards, making it appropriate for both domestic and internationally specified applications. The black luster finish provides a degree of surface protection in shop and industrial environments. It is sold individually but must be ordered in multiples of 5.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or mallet with a suitable driver to avoid damage to the pin or bore. Ensure the mating hole is reamed to the correct tolerance before installation. Power down and de-energize any associated machinery before servicing assemblies containing locating pins. Use a slide hammer or threaded extraction tool compatible with the pull out feature when removing the pin.
