Gibraltar CP-1085 Conical Pin 0.131 in 2.5 in Oal Hss

Product Description

The GIBRALTAR CP-1085 is a conical pin machined from high speed steel and finished with a nitride coating for improved surface hardness and wear resistance. The pin measures 0.131 inches in diameter with an overall length of 2.5 inches, a head diameter of 0.2358 inches, and a head height of 0.1651 inches. The conical geometry provides positive location and consistent seating in precision tooling, fixtures, and machined assemblies. It is installed by toolmakers, machinists, and fixture builders working in production or maintenance environments.

Conical pins of this type are used in tool and die work, jig and fixture construction, and machine assembly where repeatable part location is required. The nitride finish on high speed steel provides a harder surface than uncoated steel, helping the pin resist wear in moderate-cycle tooling applications. This pin suits situations where a standard dowel does not provide the self-aligning or locking action that a conical profile offers.

Key Features

• Conical profile for self-aligning, positive-location seating in fixture and tooling bores
• High speed steel construction for hardness and dimensional stability
• Nitride finish increases surface hardness and corrosion resistance compared to uncoated steel
• 0.131 inch pin diameter suits standard precision tooling bore sizes
• 0.2358 inch head diameter provides a positive stop against the mating surface
• 2.5 inch overall length accommodates typical fixture plate thicknesses

Compatibility

Designed as an OEM-style replacement or direct-use conical locating pin for precision tooling, jigs, fixtures, and machined assemblies requiring a 0.131 inch diameter conical pin in high speed steel.

Installation Notes

Conical pins are installed by qualified toolmakers or machinists. Ensure the receiving bore is clean and free of chips or debris before insertion to avoid bore damage or improper seating. Do not force the pin with impact tools unless the application specifically requires a driven fit; use an arbor press for controlled insertion when a press fit is needed. Inspect the pin and bore for wear or damage during routine fixture maintenance.
