Ensure reliable, repeatable angles.

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

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

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

Use these squares in place of your try square, miter square, depth gauge, height gauge, center-point finder, and level.

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.

The galvannealed coating allows these steel sheets to be painted without prepping the surface. They're easier to weld and more scratch resistant than zinc-galvanized steel sheets. Use them for outdoor signs, cabinets, and doors.

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.

Easy to forge, grind, and heat treat, these 1084 high-carbon steel bars offer high strength and resist wear and abrasion.

This UHSS (ultra high-strength steel) allows you to fabricate high-strength parts using thinner material than you could with other types of steel. It is formable, weldable, and more economical than alloy steel.

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.

Combining strength with weldability and formability, A572 alloy steel is an economical choice for structural components, such as channels, beams, and framing. It has a low carbon content, making it easy to weld with a variety of welding methods.

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

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

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

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

The thickness, length, and width are oversized for finishing 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.
