Gibraltar Z1262 Flat Vent Pull Out Dowel Pin 1/4 in

Product Description

The GIBRALTAR Z1262 is a flat vent pull out dowel pin used for precise alignment and locating in tooling, fixtures, jigs, and mechanical assemblies. Machined from case-hardened C1215 steel, this pin delivers a hard exterior surface with a tough core, resisting wear and deformation under repeated insertion and extraction cycles. It measures 1/4 inch in diameter with an overall length of 1.25 inches and holds a diameter tolerance of 0.0001 to 0.0003 inches. One end is beveled for guided entry; the other end is threaded for pull-out tool engagement. Machinists, toolmakers, and maintenance technicians install this type of pin in production and assembly environments.

Flat vent pull out dowel pins are specified where standard solid pins would be difficult to remove due to air lock in blind holes. The flat vent along the pin body allows air to escape during insertion and re-enter during extraction, preventing hydraulic resistance. This design is common in precision machining fixtures, stamping dies, mold bases, and automated assembly tooling. The threaded pull-out end accepts a standard extraction tool for controlled removal without damage to the bore or surrounding material.

Key Features

• Flat vent design eliminates air lock in blind-hole applications
• One beveled end for guided, low-interference entry into bores
• One threaded end for engagement with standard pull-out extraction tools
• Case-hardened C1215 steel construction for wear resistance with a tough core
• Tight diameter tolerance of 0.0001 to 0.0003 inches for precision locating

Compatibility

Designed as a standard-geometry flat vent pull out dowel pin suitable for precision tooling, fixture plates, mold bases, and mechanical assemblies requiring controlled blind-hole pin retention and extraction.

Installation Notes

Installation is typically performed by toolmakers or maintenance machinists using a press or mallet and appropriate insertion tooling. Ensure the receiving bore is clean, deburred, and dimensionally verified before installation. Power down and de-energize any associated machinery before servicing fixtures or tooling that contain these pins. Use a properly threaded extraction tool matched to the pin end when removing to avoid bore damage.
