T-Slot Fixture Plates

These plates have T-slots for fastening components with T-slot nuts, bolts, and setup studs.

Inch

These plates have three T-slots on top and a straight slot along each side for mounting with clamps.

Iron—Iron plates are heavy duty for long-term use.

Welding Fixture Squares


2 Axes With Leveling Tabs	2 Axes with Joint Access Cutouts and Leveling Tabs	3 Axes

Position your workpieces at the correct angle prior to welding. These squares have an extra-wide head, so you can clamp them in place.

Joint Access Cutouts—Squares with joint access cutouts make it easier to reach joints, such as when welding and gluing.

Leveling Tabs—Leveling tabs are for aligning workpieces with one another.

Cast Iron—Cast iron squares are durable and difficult to dent or scratch. They resist weld spatter, but they’re more likely to corrode than aluminum.

Fixture Columns

Clamp multiple parts or fixtures to these columns to speed up your machining process. Also known as tombstones, they have multiple faces for building dense, efficient setups. Each face is precision-machined for accurate positioning. Made from cast iron, these columns are rigid enough to limit vibration and stabilize your workpieces during machining.

Blank


Square	Rectangle	Cross

Blank columns can be customized to fit your application. Machine them with your own holes, T-slots, or other mounting surfaces.

Square—Square columns have four equal faces for balanced machining on each side.

Rectangle—Rectangle columns have two wide faces for larger setups and two narrow faces for smaller ones. The narrow faces can also help reduce tool interference.

Cross—Cross columns have four equal faces, similar to square columns, but cutouts at each corner give you more tool clearance.

Grid


Square	Rectangle	Cross

Grid columns have industry-standard hole patterns. The holes are lined with a precision bushing and a threaded insert to help locate fasteners, so you can clamp parts accurately and securely. Both are hardened to resist wear. These columns also come with a plastic chip plug for each hole—plug unused holes to keep debris from clogging them or causing damage.

Square—Square columns have four equal faces for balanced machining on each side.

Rectangle—Rectangle columns have two wide faces for larger setups and two narrow faces for smaller ones. The narrow faces can also help reduce tool interference.

Cross—Cross columns have four equal faces, similar to square columns, but cutouts at each corner give you more tool clearance.
