How can we improve?

3,783 Products

Raw Materials

Steel

Strong, machinable, and weldable—all with material certificates for traceability

Fluid Handling

Tube and Tube Fittings

Tube and Tube Fittings

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

Power Transmission

Shafts

Transmit power, motion, and speed between machine components

Fastening and Joining

Shims

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

Measuring and Inspecting

Plug Gauges

Verify the diameter or threads of machined holes in finished parts; also called pin gauges

Bore Gauges

Insert into a hole and expand the contacts to measure diameter

Facility and Grounds Maintenance

Rebar

Reinforces concrete to reduce the chance it will crack from expansion and contraction

Fabricating and Machining

Lathe Tool Blanks

Lathe Tool Blanks

Machine custom lathe tool bits
