Gibraltar Z1226 Dowel Pin 1/2x2 in Case Hardened C1215

Product Description

The GIBRALTAR Z1226 is a flat vent pull out dowel pin machined from case-hardened Grade C1215 steel. It measures 1/2 inch in diameter and 2 inches in overall length, with a diameter tolerance held between 0.0001 and 0.0003 inches for precise fit in close-tolerance applications. One end is beveled for easy insertion and alignment; the opposite end is threaded to allow mechanical extraction without damage to the bore. This type of pin is installed by machinists, toolmakers, and maintenance technicians in fixtures, jigs, dies, and mechanical assemblies where a removable, accurately located dowel is required.

Flat vent pull out dowel pins are used in precision tooling and production fixturing where repeated pin removal is part of the workflow. The flat vent groove along the pin body allows trapped air and lubricant to escape during press-in installation, preventing hydraulic lock in blind holes. This pin suits both shop-floor maintenance and original equipment assembly tasks in industrial and manufacturing environments.

Key Features

• Flat vent groove relieves air and fluid pressure during installation in blind holes
• Beveled lead end for fast, damage-free insertion and alignment
• Threaded pull end allows controlled extraction with a standard slide hammer or threaded puller
• Case-hardened Grade C1215 steel for surface wear resistance with a tough core
• Diameter tolerance of 0.0001 to 0.0003 inches supports close-tolerance locating applications

Compatibility

Designed as a standard flat vent pull out dowel pin for use in precision tooling, jigs, fixtures, and mechanical assemblies requiring a removable, close-tolerance locating pin.

Installation Notes

Installation and removal should be performed by a qualified machinist or maintenance technician. De-energize and lock out any associated machinery before servicing pinned assemblies. Use a properly sized threaded puller or slide hammer on the threaded extraction end — do not drive or pry against the pin body, as this can damage the bore or alter tolerances. Ensure the receiving hole is clean, within the specified tolerance range, and lightly lubricated before installation.
