Ensure reliable, repeatable angles.

Also known as carpenters’ and framing squares, these have graduations on both blades for horizontal and vertical measurements.

These squares meet Fed. Spec. GGG-S-656-E, which establishes uniform standards for square accuracy to ensure reliable, repeatable angles.

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.

Blades are for use with High-Accuracy Combination Square Heads.

Also known as bevel protractors, set bevels and measure angles with the adjustable arm.

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

These sheets and bars are zinc galvanized for good corrosion resistance.

Coated with an aluminum-silicon alloy, these sheets resist corrosion while withstanding long-term exposure to high temperatures. Use in drying ovens, furnaces, and smokestacks.

A lead-free alternative to 12L14, 1215 carbon steel contains the same amount of sulfur and phosphorus for excellent machinability. It is often used for shaft couplings, studs, and pins.

Stronger than low-carbon steel with equally good machinability, 1045 carbon steel is widely used for bolts, studs, and shafts.

The nickel and molybdenum content gives AR400 carbon steel the ability to resist wear better than all other carbon steel. It's often used as wear strips, liners, and deflector plates.

Even in low temperatures, A516 carbon steel resists breaking upon impact. Also known as pressure-vessel-quality (PVQ) steel, it is mostly used for boilers, storage tanks, and pressure vessels.

These sheets and bars are hardened for increased abrasion and impact resistance. Also known as chrome-moly steel, 4140 alloy steel resists fracturing from repeated stress.

Also known as flat stock, the thickness on these sheets and bars is held to a tight tolerance.

The thickness is oversized for finishing to your exact requirements.

4130 alloy steel has a low carbon content that provides good weldability. It's often used for structural applications.

Also known as weathering steel, this high-strength steel develops a thin layer of rust over time in outdoor environments that protects the inner steel from corrosion.

The thickness, length, and width are oversized for finishing to your exact requirements.

These W1 bars have lower amounts of alloy elements than other tool steels for excellent machinability.

The thickness on these bars is precision ground to a tight tolerance.

Also known as flat stock, these bars have an oversized thickness, length, and width for finishing to your exact requirements.

With an oversized thickness, length, and width, these bars can be finished to your exact requirements.

These levels come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Rails are drilled with consistently spaced holes for multiple mounting options that do not require machining. Use this steel bolt-together framing to build guards, tables, and racks.
