Identify threads per inch on external threads and find the center of your workpiece to line up thread cutting tools.

Install these gauges onto the jaws of electronic, dial, and vernier calipers to measure the center-to-center distance between two holes.

Attach to electronic, dial, and vernier calipers to measure slots, inside pockets, shoulders, and holes.

Replace the tip of your machine tool indicator.

Replace your try square, miter square, depth gauge, marking gauge, 90° level, ruler, and scriber with one tool.

Replace your try square, miter square, depth gauge, height gauge, center-point finder, and level. The blade on these squares meets Fed. Spec. GGG-R-791H, which establishes uniform standards for accuracy, graduations, and size.

Use these blades with Starrett High-Accuracy Combination Square Heads. They meet Fed. Spec. GGG-R-791H, which establishes uniform standards for accuracy, graduations, and size.

Attach to High-Accuracy Combination Square Blades with the included lockbolts.

Center your work by mounting these into your drill chuck or collet and lining up the pointer with the mark on the shaft.

Locate edges, shoulders, center points, and lines on your workpiece with more precision than standard edge finders.

Locate edges, shoulders, counter points, and lines on your workpiece.

Mark and transfer distances from the outer edge of an object.

A wing joint opens wide for marking and transferring large circles, arcs, and measurements.

Fit these through existing holes and mark the center of the hole in a second workpiece.

Also known as blind-hole spotters, these punches fit into closed-end holes and mark the center of a complementary hole.

Insert these punches into an existing hole and twist the handle to open the end of the punch. The point automatically centers once the punch has fit the hole size.

Push down on the spring-loaded cone to center the punch in a variety of round and square hole sizes.

Also known as transfer screws, these punches have a uniform shoulder height so you can quickly transfer multiple hole locations at once.

Also known as transfer screws, the punches in these sets can be used in any threaded hole to transfer the hole location. Use the handle to screw a punch into a hole.

Align the level to find and mark the vertical center of curved surfaces.
