​A vector-style catalog of individual, precisely-detailed technical and engineering primitives arranged in rows and columns on a flawless, solid black background. ​The object selection includes: ​Gears: Two individual large spur gears (exact, precise profile), two interlocking smaller sprockets, a worm gear. ​Hardware: Specific screw heads (Slotted, Phillips, Torx, Hex), a hex bolt, a carriage bolt, and a nut. All shown individually. ​Measurement/Physics: A precise compass rose, individual clock hands (hour, minute, second), a caliper, a pen. Short physical and mathematical formulas as clean text: "E=mc²", "∫f(x)dx", "∫dx=x+c", "ω=const", "t=d/v". Dimensional indicators like "15mm", "Ø8mm", "±0.1". ​Symbols/Tools: Hand drawing with a pen, a miniature sextant, electrical symbols (resistor, capacitor, battery, motor). ​Styling: All elements are rendered in clean, precise, dark sepia-brown (#5D4037) outlines and minimal fills. There is ample clear black space between every single object, ensuring zero overlap. The background is solid, pure black with no textures. All text and numbers are rendered in a clean, uniform, precise sans-serif typeface, optimized for vectorization.

The image shows a set of black and white gear icons on a white background. It includes various types of gears, nuts, bolts, a compass, and other objects.
