    Grid Fixture Plates for Welding

    Image of System. Front orientation. Grid Fixture Plates. Grid Fixture Plates for Welding.
    Build fixturing setups for welding onto these plates. They have 5/8” unthreaded holes with 2” center-to-center spacing, so they’re compatible with clamps, stops, V-blocks, and other components. Made from nitrided steel, they have a hardened surface that resists wear, prevents corrosion, and keeps weld spatter from sticking. They’re easy to maintain and they hold their shape over time. To add resistance to heat and spatter, apply welding antispatter to all the components in your setup.

    V-Blocks
    Mount V-blocks to the fixture plate to hold round workpieces in place.
    Multiple Studs—V-blocks with multiple studs slot into at least two grid holes, which keeps them from shifting when you move workpieces in or out. They have two rows of mounting holes, so you can position them at a 45° or 90° angle on your grid.
    Pivoting V-Blocks—Pivoting V-blocks can hold both the outer and inner diameter of your workpiece. They can go from cradling the outside of a pipe at 60°, to lying completely flat, to gripping the inside of a pipe at a 60° angle.

    Fixturing for Parts Inspection

    Image of ProductInUse. Front orientation. Coordinate Measuring Machine Plates and Fixtures. Fixturing for Parts Inspection.
    From towers and brackets to standoffs and supports, these components are the building blocks for your custom fixturing setup. They elevate parts so you can access a variety of angles for measuring and inspecting while protecting your measuring device from hitting the inspection table. You’ll often see them used with coordinate measuring machines (CMMs). They’re not for use in machining applications.

    Image of Product. Front orientation. Coordinate Measuring Machine Plates and Fixtures. Fixturing for Parts Inspection, Positioners.
    Positioners secure components anywhere along the length of their slot, similar to drop-in nuts on T-slotted rails. This gives you the flexibility to install components between the threaded holes on plates, brackets, and towers.
