254 Products

Raw Materials

Steel

Strong, machinable, and weldable—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

Stainless Steel

Stainless Steel

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

Bronze

Better wear resistance than copper and brass—all with material certificates for traceability

Copper

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

Garolite

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

Brass

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

Rubber

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

Graphite

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

Foam

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

Nickel

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

Glass

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

Ceramic

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

Zinc

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

Sealing

Backer Rods

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

Power Transmission

Lead Screws and Nuts

Lead Screws and Nuts

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

Rotary Shafts

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

Linear Shaft Supports

Linear Shaft Supports

Support linear shafts to prevent bending and rolling under loads
