Engineers, makers, and automation builders who need consistent tooth engagement and repeatable torque transfer rely on flat spur gears with tight dimensional tolerances — not generic hardware-store substitutes.\u003c\/p\u003e\n    \u003cp\u003eThis set includes 8 identical Module 1 flat spur gears machined from carbon steel. Each gear features 58 teeth with a standard Module 1 (1 mm\/tooth) pitch, an outer diameter of approximately 60 mm (2.36 in), and a bore diameter that accommodates common motor shaft sizes — typically 5–8 mm (0.20–0.31 in). The flat face profile and uniform tooth geometry ensure smooth meshing with any compatible Module 1 mating gear.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include DIY CNC gantry drives where consistent rack-and-pinion engagement is critical, small robotics joint actuators requiring compact metal cogwheels, and motor pinion assemblies in 3D printer extruder or conveyor systems where a 58-tooth module 1 spur gear delivers the right reduction ratio.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Meshes with any standard \u003cstrong\u003eModule 1\u003c\/strong\u003e spur gear, rack, or pinion.
