Professional Applications & Engineering Value
This 3/8" spherical washer solves critical alignment challenges in industrial assemblies where surface irregularities cause uneven load distribution. The black-oxide steel construction combined with Rockwell C48 hardness ensures exceptional resistance to corrosion and deformation under heavy loads. Engineered with precise 0.406" female ID and 0.688" female OD dimensions, it maintains secure fastening while accommodating 3° angular misalignment - preventing bolt bending and thread damage in machinery, structural steel connections, and automotive applications. The spherical design compensates for manufacturing tolerances and thermal expansion, extending component life in demanding environments where vibration and dynamic loads are common.
Specification Summary & Compliance
Manufactured to inch system standards with precise dimensional control: Female ID 0.406", Female OD 0.688", Male ID 0.386", Male OD 0.625", Male Radius 0.094", and Thickness 0.407"-0.438". Compliant with RoHS 3 (2015/863/EU) under exemption 6(a)-I for lead as steel alloying element and REACH (EC 1907/2006) regulations. The Rockwell C48 hardness ensures consistent performance across industrial applications requiring reliable angular correction capability.
