Gibraltar Z1208 Flat Vent Pull Out Dowel Pin 3/8 X 1.25 in

Product Description

The GIBRALTAR Z1208 is a flat vent pull out dowel pin used to locate, align, or retain components in mechanical assemblies. Manufactured from case-hardened steel to Grade C1215, this pin measures 3/8 inch in diameter and 1.25 inches in overall length. The diameter holds a tight tolerance of 0.0001 to 0.0003 inches, making it suitable for precision fit applications where repeatability matters. One end is beveled for ease of insertion, and one end is threaded to allow controlled extraction without additional tooling. Machinists, tool and die technicians, and maintenance mechanics are the typical installers of this fastener type.

This dowel pin is suited for light-duty mechanical assemblies, fixture work, and machinery maintenance applications where a pull-out style pin with a threaded end is required. The flat vent design allows air and fluid to escape during press-fit installation, preventing hydraulic lock in blind holes. Sold individually, this pin is appropriate for both original assembly and field replacement use in industrial and manufacturing environments.

Key Features

• Flat vent design prevents hydraulic lock in blind-hole installations
• One beveled end for guided insertion into bored holes
• One threaded end for controlled extraction using a pull-out tool
• Case-hardened steel construction for surface wear resistance
• Grade C1215 material with tight diameter tolerance of 0.0001 to 0.0003 inches
• Compact size at 3/8 inch diameter and 1.25 inches length for space-constrained assemblies

Compatibility

Designed as a standard flat vent pull out dowel pin for use in mechanical assemblies, fixtures, and machinery requiring a 3/8 inch diameter locating or retention pin with a threaded extraction end.

Installation Notes

Installation is typically performed by machinists or maintenance mechanics using appropriate press or hand tools. Ensure the receiving hole is clean, properly sized, and deburred before insertion. Power down and de-energize any machinery before servicing components that use this pin. Do not exceed the pin diameter tolerance specifications when selecting the mating bore to maintain proper fit class.
