GR660 A286 18-8 Plain Polishing M5 Good Quality Oxide 12 Point Flange Head Metal Bolt With Hex Nut DIN934

This precision fastening set combines a high-performance 12-point flange bolt with a standard DIN934 hex nut, offering a versatile solution for applications requiring specific material properties. The bolt is crafted from GR660 or A286 alloy, a premium iron-nickel-chromium-based superalloy known for its exceptional strength and oxidation resistance at high temperatures. It features an 18-8 stainless steel (typically 302/304) component or characteristic, providing excellent general corrosion resistance. The bolt head is meticulously polished for a smooth, clean appearance, and features a 12-point flange drive. This offering provides a bolt of exceptional quality, paired with a standard, easily sourced hex nut, allowing for flexibility in assembly.

This bolt is engineered for the most demanding applications in the aerospace, power generation, and high-performance automotive sectors. The GR660/A286 material is specifically designed for service at elevated temperatures, making it ideal for fastening turbine components, exhaust systems, and engine parts that experience extreme thermal cycling. The polished M5 size is perfect for smaller, precision assemblies where aesthetics and reliability are both important, such as in medical devices, electronic instrumentation, or custom mechanical linkages. The combination with a standard DIN934 hex nut allows the user to select a nut material that best suits the specific application, whether it be a matching high-temperature alloy or a standard stainless steel for cost-effectiveness.

The primary advantage is the GR660/A286 material, a high-temperature superalloy that maintains excellent strength and resists oxidation well beyond the capabilities of standard stainless steels. This makes the bolt suitable for critical applications involving intense heat. The polished finish provides a superior aesthetic appearance and reduces surface irregularities that could trap contaminants. The 12-point flange head allows for secure, high-torque installation in a compact package. Pairing it with a standard DIN934 hex nut offers purchasing flexibility, allowing the user to match the nut precisely to the thermal and mechanical demands of the application or to standardize on a common nut type for inventory purposes.
