How can we improve?

17,980 Products

Raw Materials

Aluminum

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

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments

Plastic

A lightweight alternative to metal and glass

Brass

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

Bronze

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

Copper

The most conductive of our metals, it excels in all types of electrical 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, with very high strength relative to its weight

Rubber

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

Garolite

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

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

Foam

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

Nickel

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

Ceramic

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

Mica

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

Wood

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

Gold

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

Lead

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

Fiberglass

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

Graphite

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

Zinc

Draws corrosion away from nearby metal; an alternative to lead for sound barriers and vibration dampers

Molybdenum

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

Tantalum

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

Kevlar

Super tough for protection against prolonged wear and abrasion

Leather

Durable and long lasting; often used for belting, lacing, and sealing applications

Platinum

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

Hard Fiber

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

Cobalt

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

Niobium

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

Felt

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

Fastening and Joining

Shim Stock

Cut into custom shapes for leveling and aligning fasteners, machinery components, and more

Shims

Align and space components on shafts, or level machinery, cabinets, and doors

Machine Key Stock

Machine Key Stock

Cut a custom length to transfer torque from shafts to components such as gears and sprockets

Threaded Rods

Anchor, connect, or hang components in a wide variety of applications

Solder

Join pieces of metal without melting the base material

Fabricating and Machining

3D Printer Filaments

3D Printer Filaments

Run through filament 3D printers to form plastic parts

Casting Metals

Melt and pour into molds to make metal parts and prototypes

Dovetail Blanks

Dovetail Blanks

Machine a blank workpiece with precut dovetails and locating slots for easy setup

Communication

Tags

Hang throughout facilities to convey information

Message Plates

Fasten to doors, walls, and plate holders to identify locations and objects

Legend Plates

Mark switches and lights on control panels for easy identification

Signs

Everything from accident prevention to traffic control to exit signs

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

Sealing

Backer Rods

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

Fluid Handling

Perforated Sheets

Perforated Sheets

Filter, sort, separate, and strain liquid or dry material

Filter Mesh

Strain particles out of various substances

Power Transmission

Shafts

Transmit power, motion, and speed between machine components
