Both of them are plum knobs, one with a nut at the bottom and the other with a screw at the bottom. These knobs are designed for sanitary environments and are commonly used in pharmaceutical and food processing facilities. Install them on the studs to locate, tighten and fix the equipment. Available in two materials: aluminum alloy and stainless steel, and the surface treatment is matte frosted finish; the assembly method has standard H7 reamed blind holes, threaded through holes and threaded blind holes. Stainless steel has good corrosion resistance and can be used under special sanitary, climatic and environmental conditions or in environments where the use of corrosion-resistant materials is mandatory by law; their edges are highly polished and have rounded edges, no horizontal ledges, and no gaps. Bacteria cannot grow. Therefore, it is widely used in chemical, food equipment and testing instruments.
