Elevn Cromo Disc Rotor Bolt ISO Torx T25

Overview

The Elevn Cromo Disc Rotor Bolts are chromoly fasteners designed for securing disc brake rotors to ISO-mount hubs. This pack of 8 bolts features Torx T25 heads and M5×8×0.8 specifications, providing secure, reliable rotor clamping without requiring specialty tools or adapters.

Key Features

• Chromoly Construction — Heat-treated chromoly steel resists stripping and provides superior strength compared to standard steel fasteners; maintains clamping force through repeated use
• ISO Mount Compatibility — Engineered specifically for ISO-mount disc brake rotors; ensures proper fitment and secure engagement with hub holes
• Torx T25 Head — Six-point internal drive resists stripping and allows precise torque application; provides better grip than Phillips or standard screwheads
• Precise Dimensions — M5×8×0.8 specifications ensure proper seating depth and thread engagement; prevents over-tightening or under-clamping
• Pack of 8 — Complete set covers both wheels plus spares for future maintenance or replacement
• Black Finish — Durable corrosion-resistant coating maintains appearance and protects against rust in wet conditions
• Reliable Clamping — Proper bolt torque maintains rotor concentricity and prevents rotor rub or warping during braking
