    V-Blocks with Clamp—Choose a block with a clamp to secure your workpiece in place. The clamp is removable and shaped to fit inside the vee, so you can face it up or down to hold a variety of workpieces. Since it’s flush with the block faces, you can position the blocks on any of their sides.
    Steel—Steel blocks are easier to machine than hardened steel, so you can customize them to fit your workpiece.
    Hardened Steel—Hardened steel blocks are more durable and wear resistant than steel blocks, so they’ll stay precise even with heavy use.
    Styles A and B—Styles A and B have mounting slots near their base, so you can attach them to work surfaces with setup clamps (not included).
    Style C—Style C have mounting slots near their base, so you can attach them to work surfaces with setup clamps (not included). They have a continuous slot, so you can clamp any of the sides.
    Style D—Style D have tapped holes, so you can mount them to face or angle plates. They have an extended base with a second vee, also known as a fishtail. The clamp is smaller than the outer width of the block—use the adjustable screw to support the block when it’s positioned on either side.

    Matched pair blocks are ground together, so their heights, faces, and grooves are identical. When you rest your workpiece across the two blocks, they keep the centerline level.
    V-Blocks with Clamp—Choose a block with a clamp to secure your workpiece in place. The clamp is removable and shaped to fit inside the vee, so you can face it up or down to hold a variety of workpieces. Since it’s flush with the block faces, you can position the blocks on any of their sides.

    Style E—Style E have tapped holes, so you can mount them to face or angle plates. They have a clamp that extends past the faces, which limits tool clearance.
    Style F—Style F have a clamp that sits flush with the faces, so you can position these blocks on any side. Switch the clamp between upper and lower grooves to adjust the height. Position the set screw at 45° or 90° to hold either square or round workpieces.

    With vees in three different sizes, these blocks can support rods and shafts in a wide range of diameters. They’re precision ground in pairs to tight tolerances, so their heights, faces, and grooves are perfectly matched. When you rest your workpiece across two blocks, they’ll keep the centerline level. Made of hardened steel, they resist wear, so they’ll stay precise even with heavy use.

    Grooves

    The V-shaped recess holds round material securely for machining. Place one of these jaws on one side of your vise and use a flat jaw on the other. They have an industry standard hole pattern that fits most manufacturers' vises, including Kurt, Chick, TE-CO, Toolex, and Palmgren.
    Jaws with vertical and horizontal grooves holds 1/2" to 1 1/4" dia. workpieces vertically and 1/4" to 1/2" dia. workpieces horizontally.

    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.

    Machine Table Clamps for Round Workpieces

    Image of Product. Front orientation. Fixture Clamps. Machine Table Clamps for Round Workpieces.
    Secure large, round parts for machining. Often paired with V-blocks, these clamps come with five lengths of chain that you can combine to fit a variety of workpieces. Join them with the included connecting links. These clamps also come with nonmarring pads, which snap into the chain to keep it from damaging your workpiece. One end of these clamps has a cam-locking hook to secure the chain to the table and lock it around the workpiece. The other adjusts the tension, pulling the chain tight for a firm hold. Mount these clamps into slot nuts or fixture plates with socket head cap screws (not included).

    Precise-Positioning V-Blocks for Grid Fixtures

    Image of ProductInUse. Front orientation. V-Blocks. Precise-Positioning V-Blocks for Grid Fixtures.
    A precision bushing inside each mounting hole helps you clamp these V-blocks onto plates, columns, and other grid fixtures with pinpoint accuracy. Their through holes match industry standard 1/2"-13 threaded holes with 2" center-to-center spacing. Made from steel, these blocks are ground to tight tolerances for a centered groove and squared faces. They’re hardened to withstand dents and wear, so they’ll hold their shape over time. A black oxide coating helps prevent corrosion.

    Vertical-mount V-blocks have counterbored through holes, so you can attach them to your fixture with precision shoulder screws (sold separately). The screws have a shoulder diameter tolerance of 0.0004" for a tight fit that keeps blocks from shifting.

    Flange-mount V-blocks have both slots and holes for more mounting options when you’re building a setup. For precise positioning, use a dowel pin to mount them through straight holes on the bottom. For more flexible positioning, mount through the slots in the base with a socket head screw. Mounting fasteners are sold separately.
