Gibraltar 428-1086 Soft Vise Jaw 6in Flat Fixed Aluminum

Product Description

The GIBRALTAR 428-1086 is a flat, fixed soft vise jaw designed for use with 6-inch vises in machine shop, fabrication, and general metalworking environments. Constructed from aluminum, this jaw measures 6 inches wide, 3 inches high, and 1.5 inches thick, providing a broad clamping face that protects finished or soft workpiece surfaces from marring and deformation. It attaches via a bolt-on method, ensuring a secure, stable fit during clamping operations. At 5.3 pounds, it offers substantial mass for a jaw insert of this size. Machinists, tool and die technicians, and fabricators will find this jaw suited to precision holding applications where workpiece protection is a priority.

This jaw is intended for installation on 6-inch capacity bench vises commonly found in machine shops, maintenance facilities, fabrication shops, and industrial production environments. The soft aluminum construction makes it appropriate for clamping aluminum stock, finished parts, or other workpieces where steel jaws would cause surface damage. Fixed jaw movement type means this part does not pivot or self-align; it replaces or supplements an existing fixed jaw position on a compatible vise body.

Key Features

• Soft aluminum construction protects workpiece surfaces from marring during clamping
• Flat jaw profile provides even, full-face contact across the clamping surface
• 6 inches wide by 3 inches high face for broad workpiece support
• 1.5 inches thick jaw body for rigidity under clamping load
• Bolt-on attachment method for secure, repeatable installation
• Fixed jaw movement type for direct drop-in replacement on compatible vises

Compatibility

Designed as a bolt-on replacement or supplemental fixed jaw for 6-inch capacity bench vises requiring a flat soft jaw insert.

Installation Notes

Installation is typically performed by a machinist or maintenance technician using standard hand tools. Power down or disengage any power-assisted vise mechanisms before removing or installing jaw components. Ensure all mounting bolt holes align correctly before torquing fasteners, and confirm the jaw seats flush against the vise body prior to use. Inspect mounting hardware for wear or thread damage during each jaw replacement.
