The GIBRALTAR CP4251-G is a soft core pin used in assembly, fixturing, and workholding applications across machining, fabrication, and general manufacturing environments. It features an 11/64 inch pin diameter and a 6 inch overall length, with a flanged head measuring 11/32 inch in diameter and 3/16 inch in height. The pin body length below the head is 5.812 inches. Manufactured from steel with a soft hardness rating, this pin is designed for applications where easy removal or replacement is required without risk of damaging surrounding components or tooling. Machinists, toolmakers, and assembly technicians are the primary installers.
This soft core pin is suited for use in jigs, fixtures, dies, and general assembly setups in both job shop and production environments. The soft steel construction allows it to be cut, ground, or modified in the field to fit custom tooling requirements. Its headed design provides a positive stop for controlled insertion depth, making it practical for repeatable locating and alignment tasks across a wide range of manufacturing applications.
Designed as a standard soft core locating pin for use in machinist jigs, tooling fixtures, and general industrial assembly setups requiring an 11/64 inch pin diameter with a headed design.
Installation is typically performed by machinists or toolmakers using hand tools or a small press. Ensure the receiving bore is clean and correctly sized before driving the pin to avoid galling or misalignment. Because the pin is soft steel, avoid striking it with excessive force that could deform the head or body. If field shortening is required, cut or grind the pin to length before installation.
