Choosing the Right Machined Washers for Your Project

Picking the ideal machined washer starts with identifying your mechanical requirements. Material choice is fundamental: stainless steel offers superior corrosion resistance, titanium delivers high strength-to-weight ratios, and alloy steel handles high-pressure scenarios at lower cost. For marine or chemical environments, opt for stainless steel machined washers with corrosion-resistant finishes.

Beyond material, size and thickness are paramount. Too thin, and the washer can deform under load; too thick, and clamping force stiffness may increase beyond spec. Measure bolt and bearing surfaces precisely, and specify tolerances that match or exceed component specifications. Finish treatments—like zinc plating, black oxide, or phosphate coatings—add protection and reduce friction. Knowing where the washer will operate (heat zones, acid exposure, or vibration range) guides your selection. Properly chosen washers minimize wear, reduce downtime, and enhance safety.
