    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.
