Fixture Plates, Angles, and Tables

Fixturing Squares

Build fixtures on multiple sides of these squares.

Fixturing Tables

Add components such as clamps, brackets, stops, rests, mounting plates, fixturing squares, risers, and V-blocks to build fixtures for welding and assembly.

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.

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.

Magnetic Sine Plates

Turn the handle to switch the magnet on and secure steel parts—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.

Locators, Supports, and Stops

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.

Economy V-Blocks

Hold and support round workpieces.

Adjustable-Angle V-Blocks

Use this block to hold workpieces at precise angles.

Miniature V-Blocks

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

Hardened V-Blocks

Use these pairs of blocks to support long, round workpieces—secure with the built-in clamps.

Machinable V-Blocks

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

Magnetic V-Blocks

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

Setup Blocks

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

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 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.

Step Blocks

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