Secure your automotive repairs and machinery projects with this 10-Set M6-1.0 x 12 mm Metric Flanged Hex Bolt Kit. Engineered from high-strength Grade 10.9 alloy steel, these fasteners offer superior tensile strength and wear resistance compared to standard Grade 8.8 bolts, making them ideal for high-stress applications like exhaust flanges, transmission pans, and motor mounts. The integrated flanged hex head distributes clamping pressure evenly across a wider area, eliminating the need for separate washers and preventing damage to the mating surface. Finished with a protective black oxide coating, these bolts blend seamlessly with dark machinery components while providing corrosion resistance. Each kit includes matching flange nuts and flat washers, offering a complete solution for furniture assembly, DIY repairs, or precision equipment maintenance. Precision-machined M6-1.0 coarse threads ensure a smooth installation and a secure, vibration-resistant fit.
