Alloy Steel M5x11.5mm Disc Bolts

12-piece set of M5x11.5mm disc brake rotor bolts, each with thread length approx. 11.5 mm (0.5 in), total length approx. 14 mm (0.6 in), and thread diameter approx. 4.6 mm (0.2 in); total set weight approx. 34 g (1.2 oz). Made entirely from alloy steel — offering higher yield strength and better fatigue resistance than standard grade 8.8 fasteners. Finished with PVD vacuum coating, creating a dense, adherent oxide surface layer that improves hardness and retains rich purple colour without fading. Thread profile is fine-pitch and tightly toleranced for secure, repeatable engagement. Designed to remain firmly seated under vibration and thermal cycling. Certified functional from –40°C to +150°C. Compatible with disc rotors on mountain bikes, road bikes, and fixed-gear bicycles.
