Gibraltar 49319G Slip Fit Diamond Locating Pin 0.3896 in

Product Description

The GIBRALTAR 49319G is a slip fit diamond straight locating pin used to accurately position and register workpieces in fixtures, jigs, and tooling setups. The diamond nose profile reduces contact area compared to a round pin, allowing it to be paired with a second locating pin to constrain a part without over-constraining it. The 0.3896-inch nose diameter and 0.5-inch nose length provide a controlled engagement zone, while the 0.875-inch collar diameter seats the pin securely in the fixture plate. Overall length is 1.5 inches. Machined from low carbon steel, this pin is a standard component used by tool-and-die makers, fixture builders, and precision machinists.

This locating pin is suited for use in production fixture plates, welding fixtures, machining jigs, and quality inspection fixtures wherever repeatable part location is required. The relieved body and slip fit tolerance allow easy part loading and unloading during high-cycle production. The 0.5-inch tail diameter mates to a standard bored receiver hole in the fixture body. A 0.125-inch chamfer length on the nose guides the workpiece onto the pin during loading.

Key Features

• Diamond nose profile allows use as a secondary locating pin to prevent over-constraint
• Slip fit tolerance for smooth workpiece loading and unloading
• Relieved body reduces surface contact and eases installation in close-tolerance bores
• Low carbon steel construction for machinability and cost-effective replacement
• 0.875-inch collar diameter provides positive seating against the fixture plate face
• Compact 1.5-inch overall length suits shallow fixture plates

Compatibility

Designed as a standard OEM-style replacement or new-build component for fixture plates and jigs requiring a slip fit diamond locating pin with a 0.5-inch tail diameter receiver bore.

Installation Notes

Installation is performed by toolmakers or fixture technicians. The receiving bore in the fixture plate should be sized to accept the 0.5-inch tail diameter at slip fit clearance before pressing or placing the pin. Ensure the fixture is secured and free of chips or debris before seating the pin to avoid cocking or bore damage. Do not force the pin with impact tools; slip fit components are designed for hand or light press installation.
