Recently, we conducted Surface Roughness Testing on a screw sample in accordance with ISO 4287, a standard that defines surface texture parameters used to evaluate the quality of machined surfaces.
Surface roughness plays a critical role in the performance of threaded components. The surface finish of a screw can influence:
β Friction during assembly
β Wear resistance
β Coating adhesion
β Corrosion performance
β Overall product quality
During the test, a stylus-type roughness tester traverses across the surface and records the microscopic peaks and valleys present on the material. The measured profile is then used to calculate roughness parameters such as Ra (Average Roughness) and other surface texture characteristics defined by ISO 4287.
For precision-engineered components, surface roughness is more than just appearance—it directly affects functionality and long-term performance.
