Gibraltar Z1200 Flat Vent Pull Out Dowel Pin 5/16x1 in

Product Description

The GIBRALTAR Z1200 is a flat vent pull out dowel pin used in precision alignment and fastening applications across industrial, mechanical, and trade assembly work. Machined from case-hardened Grade C1215 steel, this pin measures 5/16 inches in diameter and 1 inch in overall length. The tight diameter tolerance of 0.0001 to 0.0003 inches ensures reliable fitment in close-tolerance bores. One end is beveled for easy insertion and the other end is threaded for pull-out tool engagement, making extraction straightforward without damage to surrounding components. Machinists, maintenance technicians, and industrial assembly workers are the primary installers of this hardware.

This dowel pin is suited for use in jigs, fixtures, machine frames, and general mechanical assemblies where repeatable part registration is required. The flat vent groove allows trapped air and lubricant to escape during press-fit installation, reducing hydraulic lock and the risk of bore damage. It is appropriate for both light-duty and moderate-load alignment applications in shop and field maintenance environments.

Key Features

• Flat vent groove relieves hydraulic pressure during installation, protecting bore integrity
• One beveled end for guided entry into close-tolerance bores
• One threaded end for positive pull-out tool engagement and damage-free removal
• Case-hardened Grade C1215 steel for surface wear resistance with a tough core
• Diameter tolerance held to 0.0001 to 0.0003 inches for precise alignment performance
• Compact 5/16 x 1 inch size suitable for tight-clearance assemblies

Compatibility

Designed as an OEM-style replacement or direct-use dowel pin for close-tolerance alignment applications in jigs, fixtures, and mechanical assemblies requiring a 5/16-inch bore diameter.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or mallet with appropriate bore alignment tooling. Always ensure the receiving bore is clean and free of burrs before driving the pin. Use the beveled end as the leading insertion point and apply even force to avoid cocking the pin in the bore. To remove, engage the threaded end with the correct pull-out tool rather than driving the pin from the back, which can damage the bore or the pin.
