Power Transmission

Shafts

Transmit power, motion, and speed between machine components

Lead Screws and Nuts

Lead Screws and Nuts

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

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

Bronze

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

Fiberglass

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

Garolite

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

Brass

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

Ceramic

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

Titanium

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

Tungsten

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

Copper

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

Nickel

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

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

Fastening and Joining

Dowel Pins

Align parts before assembly or use as a pivot, shaft, or hinge to join moving components
