Gibraltar Z1222 Flat Vent Pull Out Dowel Pin 1/2 X 1.25 in

Product Description

The GIBRALTAR Z1222 is a flat vent pull out dowel pin used for precise component alignment and positioning in mechanical assemblies. Manufactured from case-hardened steel to Grade C1215, this pin measures 1/2 inch in diameter and 1.25 inches in overall length. The case-hardening process delivers a hard wear-resistant outer surface while retaining a tough core, extending service life in high-cycle applications. One end is beveled for easy insertion and alignment, while the other end is threaded for mechanical extraction without marring the bore. Machinists, millwrights, and maintenance technicians install this type of pin where repeatable part location or fixture alignment is required.

This dowel pin is suited for use in machine fixtures, jigs, tooling plates, and mechanical assemblies that require tight positional tolerances. The Grade C1215 free-machining steel construction is common in precision tooling and industrial maintenance applications across manufacturing, HVAC equipment fabrication, and mechanical service environments. With a diameter tolerance of 0.0001 to 0.0003 inches, it fits standard reamed or precision-bored holes for a consistent slip or light press fit.

Key Features

• Case-hardened Grade C1215 steel construction for wear resistance and core toughness
• One beveled end for guided entry into close-tolerance bores
• One threaded end for clean mechanical pull-out without bore damage
• Diameter tolerance of 0.0001 to 0.0003 inches for precision fit applications
• Compact 1.25-inch length suits shallow fixture and tooling plate installations

Compatibility

Designed as an OEM-style replacement or standard-duty dowel pin for mechanical fixtures, jigs, and tooling assemblies requiring a 1/2-inch diameter flat vent pull out style pin.

Installation Notes

Installation is typically performed by machinists or mechanical maintenance technicians. The receiving bore should be precision reamed to match the pin diameter and tolerance before installation. Power down and de-energize any equipment before accessing pinned assemblies. Use the threaded end with an appropriate extraction tool or slide hammer for removal to avoid bore damage.
