Locators, Supports, and Stops

Economy V-Blocks

Hold 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.

Machinable V-Blocks

Easier to machine than hardened steel, these blocks can be customized to fit a workpiece.

Hardened V-Blocks

Use these pairs of blocks to support long, round workpiecesâ€”secure with the built-in clamps.

Magnetic V-Blocks

Magnetic surfaces on the bottom, back, and one V face of these blocks eliminate the need for mounting clamps and bolts.

Adjustable-Angle V-Blocks

Use this block to hold workpieces at precise angles.

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.

Setup Blocks

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

Fixture Keys

Sized to fit with precision in machine table T-slots, use these keys to locate fixtures and vises on your machine table.

Hole-Mount Fixture Keys

Install these keys in a drilled and reamed hole to locate fixtures and vises on your machine table. Also known as sine keys.

Pin Punch-Out Blocks

Remove pins from workpieces by positioning the pins over the holes in these hardened steel blocks and tapping them out using a punch and hammer.

Fixture Plates, Angles, and Tables

Angle Plates with Mounting Slots

Use these plates to ensure accurate right angles and hold workpieces and fixtures perpendicular to a machine table.

Angle Plates

Ensure accurate right angles and hold workpieces and fixtures perpendicular to a machine table by securing them to these plates with clamps.

Angle Plates with Mounting Holes

Mount workpieces in precisely located holes for repeatable setups.

Any-Which-Way Angle Plates

The handle extends the full length and height of these plates for use on any of their six sides.

Fixturing Squares

Build fixtures on multiple sides of these squares.

Magnetic Sine Plates

Turn the handle to switch the magnet on and secure steel partsâ€”no need for clamps or screws.

Sine Plates

Use the tapped holes to mount your work.

Sine Bars

Measure, mark, and inspect exact angles on dies and other precision parts.

T-Slot Blocks

Mount these versatile blocks to any flat surface for machine table-style T-slot clamping. They can also be used on a machine table to clamp parts at specific angles or add more total clamping points.

Step Blocks

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