How can we improve?

3,850 Products

Raw Materials

Steel

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

Power Transmission

Linear Shafts

Pair with linear bearings to reduce friction in manual and automated systems

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

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

Fastening and Joining

Shims

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

Fabricating and Machining

Lathe Tool Blanks

Lathe Tool Blanks

Machine custom lathe tool bits

Facility and Grounds Maintenance

Rebar

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