7,024 Products

Raw Materials

Aluminum

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

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Plastic

A lightweight alternative to metal and glass

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments

Glass

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

Rubber

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

Foam

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

Brass

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

Garolite

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

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

Tungsten

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

Ceramic

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

Lead

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

Titanium

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

Carbon Fiber

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

Fiberglass

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

Cobalt

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

Hard Fiber

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

Facility and Grounds Maintenance

Deodorizers

Eliminate odors in everything from trash cans and bathrooms to machine coolant and wastewater

Building and Machinery Hardware

Padlocks

Shackle objects together, such as a door and its frame, to prevent theft or unauthorized entry

Fluid Handling

RTD Transmitters

RTD Transmitters

Send temperature readings from RTD probes in containers, tanks, and pipes to switches and PLCs

Thermocouple Transmitters

Thermocouple Transmitters

Check system temperatures from your smartphone or tablet

Measuring and Inspecting

Micrometer Check Gauges

Micrometer Check Gauges

Confirm the anvil is parallel and measure the amount of wear on your micrometer

Fastening and Joining

Solder

Join pieces of metal without melting the base material
