How can we improve?

22,901 Products

Raw Materials

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments

Aluminum

Lightweight, easy to machine, and corrosion resistant in wet environments

Plastic

A lightweight alternative to metal and glass

Brass

More machinable than copper and bronze for making nuts, hinges, and locks

Copper

The most conductive of our metals, it excels in all types of electrical applications

Bronze

With better wear resistance than copper and brass, it’s used for bearings, gears, and pump parts

Rubber

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

Titanium

The most corrosion-resistant metal we offer, with very high strength relative to its weight

Garolite

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

Tungsten

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

Nickel

An upgrade from stainless steel that withstands harsh chemicals and acids at high temperatures

Foam

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

Glass

Clear and highly heat and chemical resistant; often used in sights, lighting, and lab equipment

Carbon Fiber

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

Ceramic

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

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

Fiberglass

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

Wax

Create seals and prototypes, lubricate tools, and polish equipment

Cobalt

Slides against other materials without wearing and sticking; resists impact and rapid temperature changes

Lead

A dense insulator often used to shield against radiation and absorb sound and vibration

Molybdenum

Retains its shape and strength in extreme temperatures and conducts heat and electricity

Hard Fiber

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

Gold

Softer than copper and nearly as conductive, form it into electronic components that won't corrode

Kevlar

Super tough for protection against prolonged wear and abrasion

Felt

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

Platinum

Conductive and formable, it resists extreme heat for use in parts such as thermocouple probes

Tantalum

Conductive with a higher melting point than most metals, it’s often used in heating elements

Niobium

Conductive, corrosion resistant, and strong, even at extremely high and low temperatures

Mica

An electrical insulator that resists high temperatures; use in circuit breakers and heating elements

Power Transmission

Shafts

Transmit power, motion, and speed between machine components

Sealing

Backer Rods

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

Fluid Handling

Pipe and Pipe Fittings

Pipe and Pipe Fittings

Generally thicker and more rigid than tubing for distributing liquids and gases through your facility

Tube and Tube Fittings

Tube and Tube Fittings

Typically more flexible than pipe for carrying liquids and gases in short runs around equipment

Mixer Shafts

Replace the shaft on mixers

Building and Machinery Hardware

Slip-On Framing and Fittings

Slip-On Framing and Fittings

Insert rails into fittings and tighten screws to make guards, railings, and racks

Clamp-On Framing and Fittings

Clamp-On Framing and Fittings

Two-piece fittings let you modify assembly stations, conveyors, and racks without dismantling them

Facility and Grounds Maintenance

Rebar

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

Grab Bars

Steady and support people with limited mobility in bathrooms

Safety Equipment

Handrails

Grab while using stairs to reduce risk of falls

Fastening and Joining

Set Screws

Exert pressure at the tip to hold parts in place, unlike screws that hold material together with threads

Lighting

Light Pipes

Concentrate and direct light from the bulb on a circuit board to a display
