Machined Flange Component Flange with Threaded Bolt Holes and Cylindrical Boss Central Bore

6061-T6 and 7075-T6 are the two alloy grades most specified for a machined flange with threaded bolt holes and cylindrical boss central bore; 6061-T6 provides M6 thread stripping torque above 12 Nm in the aluminium thread engagement length for standard energy storage module and drone frame applications, while 7075-T6 is specified when thread engagement torque above 18 Nm is required in automotive and high-load structural flange applications. Threaded bolt hole true position outside ±0.1 mm forces the mating bolt to enter at an angle, generates the first thread turn out of form during rundown, and reduces the thread engagement length below the minimum. Foshan Zhengshang Precision Hardware (Foshan, Guangdong, ISO 9001, ISO 14001, ISO 45001 certified) CNC-mills this machined flange with threaded bolt holes and boss central bore at their 2,500 m² of workshop space Foshan facility on CNC milling equipment and milling & turning, with threaded hole true position, boss bore diameter, and flange face flatness measured using your drawing as reference at the first article stage. Include hole true position, boss bore diameter, thread class, and alloy grade in your RFQ package.
