How can we improve?

747 Products

Raw Materials

Steel

Strong, machinable, and weldable—all with material certificates for traceability

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments—all with material certificates for traceability

Plastic

A lightweight alternative to metal and glass

Aluminum

Lightweight, easy to machine, and corrosion resistant—all with material certificates for traceability

Copper

Our most conductive metal for electrical applications—all with material certificates for traceability

Brass

More machinable than copper and bronze—all with material certificates for traceability

Bronze

Garolite

A strong, machinable alternative to metal and plastic widely used in circuit boards and gears

Fiberglass

A lightweight alternative to metal and wood widely used in electrical and structural applications

Tungsten

Our densest metal resists wear and heat to make end mills, heat shields, electrodes, and more

Titanium

The most corrosion-resistant metal we offer—all with material certificates for traceability

Ceramic

Hard and wear resistant, it also withstands corrosion and high temperatures

Nickel

An upgrade from stainless steel to withstand harsh chemicals and acids—all with material certificates for traceability

Rubber

Compresses and bounces back to shape; often used for sealing, cushioning, and shock absorbing

Carbon Fiber

The strongest composite we offer; comparable in strength to 6061 aluminum but lighter in weight

Graphite

Compressible or conductive for making high-temperature seals, furnace parts, and crucibles

Wood

Commonly used to build ramps, crates, and prototypes or to make repairs

Foam

Pockets of air make it lighter in weight than rubber; good for packing, insulating, and sealing

Hard Fiber

Chemically treated to be hard and dense, this is the easiest composite to machine in our offering

Cobalt

Resists impact and rapid temperature changes—all with material certificates for traceability

Molybdenum

Retains its shape and strength in extreme temperatures—all with material certificates for traceability

Felt

Thicker and more absorbent than fabric for insulating, polishing, cushioning, and gasketing

Power Transmission

Linear Shafts

Pair with linear bearings to reduce friction in manual and automated systems

Rotary Shafts

Pair with gears, sprockets, and bearings to transmit rotary motion

Sleeve Splines and Bearings

Sleeve Splines and Bearings

Transmit rotary power or move loads along the length of splines

Fastening and Joining

Dowel Pins

Align parts before assembly or use as a pivot, shaft, or hinge to join moving components

Dowel Pin Stock

Dowel Pin Stock

Cut to the length you need for positioning and holding parts in place

Stick Electrodes

Stick Electrodes

Flux coated for stability and speed when welding most metals

Fluid Handling

Mixer Shafts

Replace the shaft on mixers

Corrosion-Inhibiting Rods and Pads

Corrosion-Inhibiting Rods and Pads

Protect tanks, water heaters, and heat exchangers from rust; also known as sacrificial anodes

Sealing

Backer Rods

Insert into gaps before caulking to reduce how much sealant you need and improve adhesion

Facility and Grounds Maintenance

Rebar

Reinforces concrete to reduce the chance it will crack from expansion and contraction

Measuring and Inspecting

Calibration Rods

Calibration Rods

Check and set micrometers and other measuring tools
