Fastening and Joining

Tungsten Electrodes

Tungsten Electrodes

Heat in TIG torches to create welds

Tungsten Electrode Stick-Out Gauges

Tungsten Electrode Stick-Out Gauges

Measure the distance tungsten electrodes stick out from your nozzle for consistent TIG welding

Threaded Rods

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

Shim Stock

Cut into custom shapes to align, space, and level components on dies, presses, and machinery

Measuring and Inspecting

Water Test Strips

Water Test Strips

Dip into water and a color change indicates chemicals, pH, and other conditions

Fabricating and Machining

Taps

Cut internal threads for fasteners, pipe, conduit, and more

Lubricating

Grease

Thicker than oil to evenly lubricate surfaces and stay in place

Oil

Thinner than grease to flow in smaller gaps; dissipates heat and removes dirt and metal shavings

Assembly Lubricants

Assembly Lubricants

Lubricate tight-fitting parts before sliding them together to make assembly easier

Antiseize Lubricants

Antiseize Lubricants

Prevent threaded fasteners from sticking due to rust, dirt, and heat

Dry-Film Lubricants

Dry-Film Lubricants

Goes on wet and dries to form a nonstick film that lubricates surfaces without attracting dust

Penetrating Lubricants

Penetrating Lubricants

Cut through dirt, grease, and rust to protect tools and components from wear

Powder and Flake Lubricants

Powder and Flake Lubricants

Help locks, fasteners, and hinges to work smoothly

Mold-Release Lubricants

Mold-Release Lubricants

Apply to molds before casting parts to prevent sticking, stretching, and tearing

Fluid Handling

Heat Sink Compounds

Heat Sink Compounds

Bond heat sinks to surfaces, eliminating air gaps for maximum heat transfer

Filter Mesh

Strain particles out of various substances

Pipe and Pipe Fittings

Pipe and Pipe Fittings

Generally thicker and more rigid than tubing for distributing liquids and gases through your facility

Tube and Tube Fittings

Tube and Tube Fittings

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