Gibraltar Z1230 Flat Vent Pull Out Dowel Pin 1/2x3 in

Product Description

The GIBRALTAR Z1230 is a flat vent pull out dowel pin used in precision alignment, fixturing, and tooling applications where a removable locating pin is required. Manufactured from case-hardened C1215 steel, this pin measures 1/2 inch in diameter and 3 inches in overall length, with a diameter tolerance held to 0.0001 to 0.0003 inches for consistent, repeatable fit. One end is beveled for easy insertion and the opposite end is threaded to allow extraction without damage to the surrounding workpiece. Machinists, toolmakers, and maintenance technicians install these pins in jigs, fixtures, and mechanical assemblies requiring reliable part registration.

This dowel pin is suited for light industrial and maintenance applications where a pull-out style pin with a flat vent is needed to prevent hydraulic lock during installation. The flat vent along the pin body allows trapped air or fluid to escape as the pin is seated, enabling smooth insertion into blind holes. It is a single-unit packaged item with a minimum order quantity of one, making it practical for repair, replacement, or prototype work in shop and field environments.

Key Features

• Flat vent design prevents hydraulic lock in blind hole applications
• Case-hardened C1215 steel construction for wear resistance and strength
• One beveled end for guided insertion into bores
• One threaded end for mechanical pull-out without marring the workpiece
• Diameter tolerance of 0.0001 to 0.0003 inches for precision locating fit
• Single-piece packaging suitable for replacement and low-volume use

Compatibility

Designed as a standard-geometry flat vent pull out dowel pin for use in jigs, fixtures, and mechanical assemblies requiring a 1/2-inch diameter locating pin with pull-out capability.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using hand or arbor press equipment. Ensure the receiving bore is clean, properly sized, and free of burrs before inserting the pin. The beveled end should be oriented toward the bore entry to guide alignment. When removing the pin, engage the threaded end with the appropriate extraction tool to avoid damage to the pin or the host component.
