These innovative step screws solve complex fastening challenges by combining multiple diameters in one precision-machined component. The free-machining 303 stainless steel resists thread galling during installation, while the fully annealed condition allows custom modifications. Three essential uses: 1) Precision optical equipment requiring exact component spacing and vibration resistance. 2) Electronics enclosures with varied material thicknesses needing single-fastener solutions. 3) Medical device assemblies where sterile-compatible materials are mandatory. The screws are available with custom step configurations and can be supplied with Loctite pre-applied for permanent installations.
