Multipurpose Low-Carbon Steel

Low-Carbon Steel 90° Angles

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.

Zinc-Galvanized Low-Carbon Steel 90° Angles

These 90° angles are zinc galvanized for good corrosion resistance.

Low-Carbon Steel U-Channels

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.

Low-Carbon Steel T-Bars

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.

Low-Carbon Steel H-Bars

Made of stiff low-carbon steel to deflect less under load, these H-bars are commonly used in machine bases, construction, platforms, and frames.

Low-Carbon Steel I-Beams

Made of rigid low-carbon steel, these I-beams are often used in construction, framing, lifting, and hoisting applications.

Brackets

Corner Brackets

Also known as angle brackets.

Corner-Reinforcing Brackets

Strengthen corners of cases and crates.

Offset-Surface Brackets

Flat-Surface Brackets

Crate-Building Brackets

Clamp these brackets to panel edges to quickly assemble crates.

Sensor and Switch Mounting Brackets

Position proximity, photoelectric, and light beam sensors and switches.

Side-Hook Lift-Off Panel-Hanging Brackets

Fit brackets together to assemble truck racks, gates, crates, and fences.

Angle Measuring

Starrett Protractors with Adjustable Arms

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

Starrett Protractors with Graduated Arm

Measure angles and dimensions with one tool.

High-Accuracy Squares

Ensure reliable, repeatable angles.

High-Accuracy Square Sets

Ensure reliable, repeatable angles.

Squares with Graduations on Both Blades

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

Squares with Adjustable Blade

Measure and mark material exactly where you need to with a sliding blade.

Starrett High-Accuracy Squares

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

Starrett High-Accuracy Combination Square Blades

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.

Starrett High-Accuracy Combination Square Heads

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

High-Accuracy Combination Square Blades

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

Angle Identifiers

These gauges have 18 leaves that swing out when you want to quickly check an angle. They're more convenient than a protractor when identifying 45° and smaller angles.

Angle Block Sets

Create and check angles with these precision-ground blocks. Each block is labeled with its angle.

Structural Framing

T-Slotted Framing Structural Brackets

Connect T‐slotted rails and reinforce joints for structural stability.

T-Slotted Framing Mounting Brackets

Attach sensors, tubes, and other components to T-slotted framing rails and structures.

Flat and L-Shaped Bolt-Together Framing and Fittings

Aluminum Bolt-Together Framing and Fittings

Half the weight of steel, this aluminum framing resists corrosion in wet environments.

Steel Bolt-Together Framing and Fittings

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.

Corner Strut Channel Brackets

Surface Strut Channel Brackets

Wraparound Strut Channel Brackets

Designed to wrap around the sides of strut channel, these brackets provide a stronger hold than other strut channel brackets.

Strut Channel Shelf Brackets

A tab on the end of these shelf brackets fits inside the strut channel for extra stability.

Strut Channel Pivots

Position two strut channels at a 30° to 60° angle, then tighten the bolt to secure.

Metal Panels

Close off openings in structures while allowing air to pass through.

Clamping and Workholding

Angle Plates with Mounting Holes

Mount workpieces in precisely located holes for repeatable setups.

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.

Fixturing Squares

Build fixtures on multiple sides of these squares.

Setup Blocks

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

Shelf Brackets

Multi-Position Heavy Duty Fold-Away Shelf Brackets

These brackets allow you to lower your shelf 10 or 20 degrees.

Heavy Duty Fold-Away Shelf Brackets

These brackets have greater weight capacities than standard duty fold-away shelf brackets.

Fold-Away Brackets for Drop-Leaf Shelves

Fold-Away Shelf Brackets

Heavy Duty Shelf Brackets

These shelf brackets have a 500-lb. capacity—twice the capacity of our other shelf brackets.

Shelf Brackets

Shelf Brackets with Garment Rod Holder

Threaded Rod Mounts

Fasten these brackets to ceilings, walls, beams, and joists to hang threaded rod.

Steel Hat Channel

In addition to creating space inside walls or ceilings—to prevent dampness or make room for insulation—these channels can also be used to level or resurface them.

Stacking Caps and Targets

Weld these caps and targets to the ends of posts to create stackable shelving and racking systems.
