Clamping and Workholding

Setup Blocks

Use these tight-tolerance blocks as mounting bases and supports to ensure accurate angles and spacing.

Setup Shims

Fine-tune height, spacing, and alignment when working with 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.

Economy V-Blocks

When high precision isn’t critical, choose these V-blocks to hold and position round workpieces.

V-Blocks

Precision ground to tight tolerances, these V-blocks help you accurately align and support round workpieces.

Miniature V-Blocks

Place into larger V-blocks to hold small shafts and cylinders. Sets include two clamps that fit different diameters.

Any-Size V-Blocks

To hold and support large or small round or cylindrical workpieces, position these two-piece V-blocks to accommodate any diameter.

V-Blocks for Magnetic Workholding

Set these V-blocks onto a magnetic chuck or plate to lock metal workpieces in place—no fussing with clamps or bolts.

Three-Way V-Blocks

With vees in three different sizes, these blocks can support rods and shafts in a wide range of diameters.

Step Blocks

Use these blocks to support step setup clamps. Fit the nonslip steps together for quick height adjustments.

Step Block Sets

Keep a variety of step blocks on hand to make quick height adjustments to your setups.

Slotted Support Blocks

Position T-slot side clamps at any angle you need to hold workpieces.

Measuring and Inspecting

Mitutoyo Gauge Block Sets
with Calibration Certificate

Use the Mitutoyo gauge blocks in these sets individually or together to take precise measurements or calibrate your measuring tools. All come with a certificate traceable to NIST to certify they were calibrated in a lab and meet tight tolerances.

Mitutoyo Gauge Block Sets

Use the Mitutoyo gauge blocks in these sets individually or together to take precise measurements or calibrate your measuring tools. They are often used to mark layouts, align machine components, and check that parts are within tolerance.

Starrett Gauge Block Sets with Calibration Certificate

Use the Starrett gauge blocks in these sets individually or together to take precise measurements or calibrate your measuring tools. All have been laboratory calibrated and include NIST traceable certification with the tested measurements.

Gauge Block Sets

Use the gauge blocks in these sets individually or together to take precise measurements or calibrate your measuring tools.

Angle Block Sets

Create and check angles with these precision-ground blocks. Each block is labeled with its angle.

Durometer Hardness Test Block Sets

Confirm your durometer hardness tester is taking accurate readings.

Granite V-Blocks

Made in pairs, these V-blocks are precision ground to tight tolerances for straight sides, square corners, and centered grooves.

Ball V-Blocks

Use these V-blocks to support rods, shafts, and other cylindrical workpieces for precise inspection or measuring tasks.

Granite 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.
