Gibraltar Z1202 Flat Vent Pull Out Dowel Pin 5/16x1.25in

Product Description

The GIBRALTAR Z1202 is a flat vent pull out dowel pin machined from case-hardened Grade C1215 steel. It measures 5/16 inch in diameter and 1.25 inches in overall length, with a diameter tolerance of 0.0001 to 0.0003 inch for precise fitment in close-tolerance applications. One end is beveled for easy insertion, and the opposite end is threaded for controlled extraction without marring the bore. This pin is used in mechanical assembly, fixturing, and tooling work where a removable, accurate locating pin is required. Machinists, millwrights, and tool-and-die technicians are the primary installers.

The Z1202 is suited for production and maintenance applications where a dowel pin must be pulled out rather than driven or pressed. The flat vent groove along the pin body allows trapped air and lubricant to escape during insertion, reducing hydraulic lock in blind holes. It is a standard single-piece item packaged individually, making it appropriate for both bench-stock replenishment and one-off repair jobs in machine shops, fabrication facilities, and industrial maintenance settings.

Key Features

• Flat vent groove prevents hydraulic lock in blind-hole applications
• One beveled end for guided, low-force insertion
• One threaded end for controlled pull-out without bore damage
• Case-hardened Grade C1215 steel for wear resistance and surface hardness
• Tight diameter tolerance of 0.0001 to 0.0003 inch for precision locating
• 5/16 inch diameter x 1.25 inch length — compact form for space-constrained assemblies

Compatibility

Designed as a standard-dimension flat vent pull out dowel pin for use in machined bores and fixtures requiring a 5/16 inch locating pin with pull-out capability.

Installation Notes

Installation and removal should be performed by a qualified machinist or millwright. Apply a light film of lubricant to the pin before insertion to prevent galling. Always power down and de-energize any equipment before servicing components that use locating pins. Use the threaded end with an appropriate extraction tool or slide hammer adapter — do not drive the pin out from the threaded end with a hammer.
