    Clamps for Parts Inspection

    Image of ProductInUse. Front orientation. Coordinate Measuring Machine Plates and Fixtures. Clamps for Parts Inspection.
    With a light yet sturdy hold, these clamps help you keep workpieces in place hands-free for measuring and inspecting. Thread them right into your fixturing surface, whether it’s a plate, tower, or table. Because they apply less pressure than machining clamps, they won’t distort your parts, so you can take accurate measurements. While these clamps aren’t sturdy enough for use in machining, you can still use them for light fabrication work, such as laser engraving.

    Hold-down clamps secure parts from the top.
    Tension Spring—Tension spring clamps are the most common type of clamp. Slide the arm down the shaft until it touches the top of your workpiece. Since you apply pressure directly, using too much force might move your part.
    Wire Tension Spring—Wire tension spring clamps have a slimmer profile than standard clamps, which means they don’t cover up as much of your workpiece. They’re often used to clamp small parts. Pull the wire arm away from the shaft, position your part, then release the arm so it moves back to cradle your part in place.
    Thumb Screw—Clamps with a thumb screw give you more control over the pressure you apply on a workpiece than tension spring clamps. Twisting the screw moves the clamp up or down in small increments, so they’re less likely to dent or scratch your workpiece. The knurled head on the screw is slip resistant, letting you make precise turns with reliable grip.
    Squeeze Tabs—Clamps with squeeze tabs on the back are best for supporting delicate parts. They have the lightest touch of any clamps we offer, because the tension is held in the tabs rather than the clamp itself. Press the tabs together like a clothespin and rotate the clamp where you need it.
    Rubber-Coated Tip—Clamps with a rubber-coated tip are less likely to scrape parts than clamps with an uncoated tip.

    Granite Inspection Parallels

    Image of Product. Front orientation. Inspection Parallels. Granite Inspection Parallels.
    Support and align workpieces for precise measuring and inspecting. Made of black granite, these inspection parallels won’t rust or warp from temperature changes, and they won’t scratch surfaces. Unlike metal inspection parallels, they’re also nonmagnetic, so they won’t interfere with sensitive electronic equipment. Made in pairs, these inspection parallels are precision ground to tight tolerances for matching flat surfaces on two or four sides. They come with a certificate traceable to NIST confirming their accuracy.
    2 Precision-Ground Sides—Inspection parallels with 2 precision-ground sides have a tight parallel tolerance on the top and bottom edges.
    4 Precision-Ground Sides—Inspection parallels with 4 precision-ground sides have a tight parallel tolerance on the top edge, bottom edge, and both faces.
    Inspection-Grade A Plate—Inspection Grade A inspection parallels are used for general inspections and quality-control work. They’re slightly less precise than Grade AA ones.
    Laboratory-Grade AA Plate—Laboratory Grade AA inspection parallels have the tightest tolerance for the highest level of accuracy. They’re best for inspections and quality-control work in calibration labs.

    Meters for Solar Power Systems

    Find the best spot for new solar panels or check the performance of existing ones. These tools measure solar power in different ways, helping you comply with IEC 62446-1, a standard for testing, documenting, and maintaining solar panels connected to the grid. The data hold function freezes a measurement on the screen, so you have time to write it down. CE marked, all meet European safety standards.
    Solar Irradiance Meter Kits
    Image of Product. Front orientation. Light Meters. Meters for Solar Power Systems, Solar Irradiance Meter Kits.
    Solar irradiance meter kits include tools to measure current and voltage, so you can check if your panels are generating the expected power. To test current, position your panel’s wiring within the jaws of the clamp meter. Or, if your wiring is hard to reach or clamp around, attach the flexible AC probe to the clamp meter and loop it around your wiring. Neither method will interrupt your circuit, making frequent measurements possible. To measure voltage, wire the clamp meter’s test leads to your solar panel or power station.

    Style D with Clamp (Side Orientation)

    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.

    Take current measurements from a distance with these high-quality, durable Fluke meters. They wirelessly transmit readings to a separate display. Because the jaws surround a cable, these meters are convenient for taking frequent measurements since you don't have to interrupt the circuit.
    The meters work with the Fluke 3000 FC multimeter, a computer with a Fluke pc3000 FC connector plugged in (not included), or a mobile device that has the Fluke Connect app.
    True RMS AC Calculation—These true RMS current meters take accurate AC measurements regardless of the load type or sine wave shape. This is important for testing electronic devices that draw current in short pulses that can distort the shape of the wave, such as computers and adjustable-speed drives.
    Display Count—Display count is an industry designation and not an actual value. For example, a 1,000-count meter shows numbers up to 999. A higher display count means the meter can give a more precise measurement.

    Granite Inspection Setup Blocks

    Image of Product. Front orientation. Inspection Setup Blocks.
    Machined in pairs, these blocks are precision ground to tolerances thinner than a sheet of paper to give you the flattest and squarest surface for positioning workpieces. Since they are perfectly aligned to one another, they’ll keep your workpieces level and parallel. Also known as 1-2-3 blocks, they're typically used to elevate, support, and align parts for measuring and inspecting. They're made from granite, so they won’t scratch the surface of your workpiece. They also won’t warp when temperatures fluctuate. Unlike metal blocks, these granite blocks are nonmagnetic, so they won’t interfere with sensitive electronic equipment. They come with a certificate of accuracy that's traceable to NIST.
    Inspection-Grade A Plate—Inspection-grade A blocks are your go-to for general inspections and quality-control work. These blocks are slightly less precise than grade AA blocks with double the tolerance.
    Laboratory-Grade AA Plate—Laboratory-grade AA blocks are best for precision inspections and quality-control work in calibration labs. These blocks have the tightest tolerance for the highest level of accuracy.

    Ball Support

    Ball Bearing Support

    Use these inspection V-blocks to support rods, shafts, and other cylindrical workpieces for precise inspection or measuring tasks. The round surfaces reduce pressure on your workpiece, which helps prevent damage.
    Ball Support—Inspection V-blocks with ball supports are used for detecting lobes and out-of-round conditions. The balls don’t rotate—instead, they distribute your workpiece’s weight across eight stable points of contact. They also absorb impact, which prevents marring and surface distortion.
    Ball Bearing Support—Inspection V-blocks with ball bearings are used to measure runout, straightness, and concentricity on shafts and other round parts. The bearings spin freely, which reduces friction and allows you to rotate your workpiece smoothly and consistently.
