The SRAM Vierkantmutter is a small but essential hardware component designed to keep your bike’s components securely mounted and running quietly. "Vierkantmutter" translates to square nut, a shape commonly used in bicycle assemblies where a secure, non-rotating interface is needed, for example in brake mounts, cable guides, or accessory brackets. As a genuine SRAM part, it is engineered to precise tolerances so it fits correctly with matching SRAM bolts and hardware, helping to prevent loosening, rattling, or premature wear over time.
Using original SRAM hardware like the Vierkantmutter ensures compatibility with a wide range of SRAM-equipped bikes, from mountain and road to urban and trekking setups. It is ideal for mechanics and home tinkerers who want to replace lost or worn fasteners with reliable, brand-specific parts instead of generic substitutes. Whether you are completing a detailed rebuild, upgrading components, or simply solving an annoying rattle, this square nut offers a simple, durable solution that restores confidence in your bike’s structural connections.
