15,813 Products

Raw Materials

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Aluminum

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

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments

Plastic

A lightweight alternative to metal and glass

Tungsten

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

Bronze

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

Ceramic

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

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

Lead

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

Nickel

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

Fastening and Joining

Shim Stock

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

Shims

Level, align, and adjust spacing on fasteners, shafts, and machine components

Fabricating and Machining

Core Pins

Add to molds and pour in plastic to form holes in finished parts

Ejector Pins

Push finished parts out of molds

Ejector Blades

Flat end pushes thin-walled parts out of molds better than ejector pins

Ejector Sleeves

Ejector Sleeves

Use with mold pins to form holes, bosses, and other features in parts

Punch Pins

Use with press dies to punch 1/8" and larger holes; modify to fit your application

Power Transmission

Shafts

Transmit power, motion, and speed between machine components

Springs

Apply and absorb force with compression, die, extension, torsion, and disc springs

Lead Screws and Nuts

Lead Screws and Nuts

Components travel along a screw with broad, square threads to clamp and lift heavy loads

Roller Screws and Nuts

Roller Screws and Nuts

More contact points to move heavier loads than ball and lead screw assemblies

Measuring and Inspecting

Surface Plates

Extremely flat to give an accurate reference plane for layout and inspection work

Surface Plate Stands

Surface Plate Stands

Hold up surface plates at precise support points to maintain accuracy

Fluid Handling

Filter Mesh

Strain particles out of various substances

Perforated Sheets

Perforated Sheets

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

Tube and Tube Fittings

Tube and Tube Fittings

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