    Setup Blocks

    Create setups with precise angles and accurate spacing for measuring, inspection, or machining. These blocks are precision ground to tight tolerances on all six faces, making them flat, square, and parallel. Made of hardened steel, they resist wear, so they’ll stay precise even with heavy use.

    Magnetic Setup Block and Setup Shim Sets

    Image of Product. Front orientation. Setup Blocks. Magnetic Setup Block and Setup Shim Sets .
    Support metal workpieces at precise angles or create accurate spacing with the blocks and shims in these sets. The blocks have neodymium magnets—powerful rare earth magnets—embedded in one face for a strong hold on shims or other metal surfaces. Their surface is hardened for durability and wear resistance. The shims are not hardened, but they have a black-oxide coating that helps prevent corrosion and wear. Blocks are ground parallel and square on all six sides, and the shims are ground on both faces.
    Magnets may lose their holding power at temperatures above 175° F, so avoid extended heat exposure.

    Sets of Parallels

    Keep multiple sizes of matched pairs on hand in one protective case. These parallels elevate, support, and align workpieces in machining, grinding, and inspection setups. They are precision ground to ensure accurate positioning in vises while providing additional clearance for cutting tools. Durable and wear resistant, parallels are made of hardened steel. They’re a rugged solution for shop-floor setups and heavy duty applications. To use, place a parallel against each vise jaw and rest the workpiece on top. You can also use them as reference surfaces for measurement and alignment.

    Wave—These parallels make continuous contact that's spread across multiple points. They support thin, irregular, and soft workpieces without damaging them. The wave shape also creates space for chips and debris to fall away.

    Setup Blocks for Welding

    Designed to fit your welding fixturing system, these blocks make great mounting bases, supports, or positioning stops. The holes are spaced to fit with locating pins, clamps, and other accessories, so they’re ideal for repeatable setups. They don't have tight tolerances, so choose a different block for precision machining or inspecting. A black-oxide finish protects them from corrosion and wear.
    Sets of Engraved Blocks
    Image of Product. Front orientation. Contains Annotated. Setup Blocks. Setup Blocks for Welding , Sets of Engraved Blocks.
    Engraved blocks have dimensional offset increments that are laser engraved on both sides. Use them to position these blocks at a set distance from a fixturing hole without a measurement tool.

    Sets of Adjustable Parallels

    Adjust these two-piece parallels to your exact height requirements. Loosen the one or two screws and slide the pieces in and out. When the desired height is achieved, tighten the screws. Parallels are precision ground and often used in pairs. Place a parallel against each vise jaw and rest your workpiece on top to raise it within the vise, allowing more clearance for cutting tools. Parallels also function as adjustable gauges for layout, setup, and inspection tasks.

    Parallels for Magnetic Workholding

    Image of Product. Front orientation. Parallels. Parallels for Magnetic Workholding.
    Use with magnetic workholding chucks and plates to extend their holding power above the working surface. These parallels are laminated with 1/16"-thin layers of iron and stainless steel for a strong, consistent hold. Compared to parallels made from aluminum or brass, these are harder and more dent resistant, so they hold their shape over time. Each layer is entirely fused together with copper brazing, so you can machine these parallels without the layers separating. Note: Parallels are not magnetic on their own.
    Sold as Matched Pair—Manufactured and ground together to ensure they are parallel and square to each other with a tolerance of 0.0002".
