metal hex bolt 3d model

A heavy-duty industrial hex bolt made of brushed stainless steel, highly detailed 3D model. The bolt has a large circular flat head with the letters "TR(just like the picture)" engraved deep into the surface — bold, angular typography, like a brand logo stamp. The shaft has precise machined threads running along the full length. Material is polished and brushed metal with realistic metallic reflections, slight scratches and machining marks on the surface. The head top face shows the "TR" monogram centered, with beveled edges on the engraving. Studio lighting, photorealistic, hard surface model, mechanical engineering style.
