Spectre bolt caps cover and refresh the look of aged or degraded bolt heads with a high‑quality triple chrome‑plated finish. Engineered to fit over 7/16" and 10mm bolt heads, these caps install without special tools and are claimed to resist loosening, vibration and falling off. They provide a quick cosmetic upgrade while retaining functional fit for exposed fasteners.
